V4 Development Board: The LoRa 32 V4 is a brand-new upgraded version of the classic LoRa development board. While maintaining the powerful features of its predecessor, the V4 version features comprehensive optimizations in hardware design, power management, and scalability. Suitable for IoT applications such as smart cities, agricultural monitoring, smart homes, industrial control, security systems, and wireless meter reading, it provides developers with a more efficient and flexible development experience.
Powerful Connectivity: Our development board is equipped with dedicated 2.4GHz metal spring antennas and rubber rod antennas for Wi-Fi and Bluetooth, and a reserved LoRa U.FL interface ensures stable, long-range wireless communication. A new SH1.25-8-pin GPS interface facilitates positioning expansion. It also features a rich set of peripheral interfaces. The development board’s form factor and pinout are compatible with LoRa 32 V2 and V3 versions, and additional external pins enhance scalability.
Hardware Upgrade: Our V4 development board utilizes the ESP32-S3R2 and SX-1262 chipsets, but removes the CP2102 serial port chip. It features a 0.96-inch display with a fully protected screen structure, ideal for displaying debugging information and battery status. It also includes 2MP of internal SRAM and 16MB of external SRAM. The flash memory easily handles complex firmware. The high-power version of the LoRa system boasts an increased transmit power of 27±1dBm, ensuring stable communication. The GNSS interface consumes less than 20uA, maintaining its low-power design. The PC case fully encloses the screen and integrates a 2.4GHz antenna, enhancing overall strength and integration.
Upgraded power management: The development board features a built-in 3000mAh battery and a unique N39 protective case. The N39 case is compatible with both V3 and V4 development boards. You can easily charge via the Type-C port, which integrates voltage regulation, ESD protection, and short-circuit protection. Alternatively, you can use the SH1.25-2P solar connector, compatible with solar panels up to 4.4-6V/540mA. This innovative design ensures your WiFi LoRa 32 (V4) remains powered and ready for use. Supporting charge and discharge management, overcharge protection, battery level detection, and automatic USB/battery power switching, this ESP32 kit is the ideal choice.
Strong compatibility and developer-friendly design: This ESP32 LoRa Ar duino development board supports Ar duino. The development environment can be easily integrated with existing projects and compatible devices such as for Raspberry Pi. With 2MP of internal SRAM and 16MB of external Flash, it can easily handle complex firmware and facilitate program download and debugging, making it an ideal choice for both novice and experienced developers.
Note: The securing screw in the upper left corner of the screen is a special plastic screw, unlike the other three. This screw prevents interference with the 2.4GHz radio frequency and is not a product defect.If you encounter a black screen or motherboard malfunction: This is because the stable system does not support firmware V4. You can try using version 2.7.11 or 2.7.12. Please flash the firmware first. This issue is most likely caused by flashing the wrong firmware.
Note:Regarding firmware updates, the ESP32 requires the use of BOOT mode in some cases; this is a chip characteristic. This is mentioned in the FAQ on the official website and online documentation. Regarding the battery interface, it is a standard size. Meshtastic’s 2.7.12 Bluetooth connectivity had flaws; these issues have been fixed in 2.7.13, which also removed power limitations in most regions. The downgraded version 2.7.11 imposed numerous restrictions on RF power.

Great little mesh radio
So, this was my introduction to Meshtastic. Kind of like a gateway drug, you get started and can’t quit. Build quality is great. Everything lines up and fits tightly. The display is a bit small but useful. It works as expected and shows more than 80 nodes in my area when connected. Battery life is as expected for a v4 LoRa. I get about a day of use between charges. Great value for the money.

Decent kit
V4 board is nice for the most part, I agree with others that the placement of the power connectors was very poorly planned. Known to be power hungry, battery is down to 50% after 10-12 hours. My T1000 only loses about 25% in the same time, and has a much smaller battery.N39 case – the purple color was kinda neat. Dimensionally it’s not half-bad, but the SMA antenna connector doesn’t extend far enough to put the nut on it and still get an antenna on. I’ll be sanding it down until it fits properly. Aside from that the form factor is decent, well laid out, fairly easy to assemble but I would recommend putting some glue on the nuts to hold them in place, they like to vanish if you take the screws out. Attach all cables and test the layout and routing before final assembly. You could 3D print your own, I’m sure it would be much better if it were injection molded.

Good overall quality and performance. 4.5 Stars
Work well. Fun to play with and the simple buttons work so much better than the lousy “joystick” on the other model that I had to return. After looking up on Reddit and Meshtastic the GPS function, apparently it is a feature not a bug that they show up in a different place on the map, with the default setting obfuscating the exact location for privacy. Assembly based on the photos from this page were good overall, but I had to back up a step to loosen the circuit board to get space to attach the battery.

just put the pressure ring and the antenna will fit
I’ve had no issues with the antenna — it fits perfectly when using only the pressure ring. The range is much better now: with the V3 I couldn’t find a single node in my area, and now I’m detecting more than three. I love the design and it’s definitely worth the money.Assembly was very intuitive. Just remember to connect the LoRa antenna before inserting the battery. I also checked the battery polarity and it was correct.

Excellent LoRa radio node 👌
This node is great! The kit is like a setup kit, the antenna isn’t anything special, but the case and the whole setup is just excellent! Keep in mind that the Heltec V4 board comes with all hardware that normally comes with THE BOARD itself. The nut and washer is not necessary! If you choose to use the nut, it broadcasts, but the antenna barely makes contact. If you just remove the nut and also exclude the washer, it will have a much better mechanical connection. I couldn’t be happier with my purchase! I hope more people get into LoRa radio and support open-source-friendly companies like Meshnology. I am going to be getting more of their kits in the future for sure. Great work Heltec, Meshnology, and Meshtastic.

Antenna fitment issues.
I like the form factor of this case. My only complaint is where the antenna connector fits into the case. It is a little too tall for the antenna to make a good/reliable connection. It is an easy fix to just sand it down a little. I have included a photos with one sanded down and one that isn’t.

HelNOPE! Stay away from this kit.
What a massive disappointment!This physical design is wildly counterintuitive. The components are arranged so that the cables are unnecessarily twisted, and what should be a simple assembly is beyond tedious.The boards are flashed with a nasty mishmash of busted firmware. Plan to spend several hours straightening it out.The batteries are rated at 3000mAh, but can barely sustain three hours of uptime.I haven’t been so profoundly let down by a product since I can remember.Steer clear.

Tight fit
the Lora antenna adapter thread is too short for the case if the nut is attached. Screwing the antenna in without the nut will assure solid connection. The housing holding the adapter is too thick. The battery connector is very tight to the edge. The v4 connectors for battery and solar are mounted so the cable exits to outside edge causing a short squeeze Against the case edge. Solved by routing one lead upwards and one downwards. This also requires the battery to be connected and activating the board so make sure the antenna is connected before or turn of transmit before any mechanical work. One also has to be careful one using the screws to not drop them on the boards while affixing it into the case. Looks like oversights by the board or case designer. But otherwise a nice case

Exactly what I needed, this case fitted my HELTEC V4 and 3000mah pillow battery. No messing around with fitment. Easy to put together.

Antenne passt nicht, wie in der Anleitung beschrieben. Die Firmware, die vorinstalliert ist, endet mit einem Reset und ist nutzlos. In der Anleitung fehlt der Link, wo man die richtige Firmware findet. Batterie hält ohne W-Lan nur 24 Stunden, was für ein low-power device echt nicht viel ist. Sonst bin ich mit dem Empfang und der Verarbeitung ganz zufrieden. Reichweite in der Stadt zwischen 2 Geräten ohne viele Gebäude dazwischen ca. 1,2km.

Auch ohne Anleitung leicht zu montieren, wenn man einigermaßen geschickte Finger hat und etwas technisches Verständnis.Ärgerlich ist, dass der Antennensockel, also das Gewinde für die Antennenbefestigung, welcher mit dem Gehäuse zu verschrauben ist entweder zu kurz, oder das Gehäuse an der Aufnahme zu dick ist. Benutzt man nur die beiliegende Mutter um das Teil mit dem Gehäuse zu verschrauben, also nicht auch die beiliegenden Scheiben, reicht das Gewinde nicht mehr, um auch die Antenne aufzuschrauben. Also muß man die Mutter weglassen. Dann wird das ganze aber nicht fest und die Antenne wackelt im Gehäuse! Das is eindeutig auf einen Konstruktions-, oder einen Fertigungsfehler zurückzuführen. In Kommentaren wurde das schon vor längerer Zeit bemängelt. Da es die Geräte längere Zeit nich gab, nahm ich an, dass in der Zeit dieser Mangel behoben wurde, aber nein. Jemand schrieb in den Kommentaren, dass er etwas vom Gehäuse abgeschliffen hat und dann passte es. An der Stelle ist das Gehäuse geschätzt 5…6 mm dick, so dass man durchaus 3 mm abschleifen könnte. Das habe ich versucht. Bereits nach einem Millimeter zeigte sich ein“Lunker“ im Gehäusematerial, so dass ich nicht mehr abschleifen konnte, ohne die Gehäusestabilität zu beeinträchtigen. Also wackelt die Antenne weiter! Das ist einfach Murks und sollte so nicht verkauft werden, schon gar nicht bei dem Preis! Nun bin ich mal gespannt, wenn ich das Gerät in Betrieb nehme, ob da wenigstens alles funktioniert! Ich werde dazu später meinen Negativkommentar noch ergänzen.

Also das Gerät ist schon nicht schlecht, aber jetzt kommt es die Reichweite vom GPS ist nicht gut
