Solid performance
Very stable connection over long distances. The only reason for 4 stars is that the case needs to be purchased separately, but the board itself is top-notch.

Great hardware, minor docs issue
The nRF52840 chip provides plenty of power for custom development. Documentation could be slightly more detailed for beginners, but the community support fills the gap.

Best value dev board
Incredible value for money. Having Bluetooth, LoRa, and GPS on one compact board simplifies my prototype designs significantly.

Easy to flash and configure
Flashing custom firmware via USB-C was seamless. Great tool for learning about LoRaWAN networks without breaking the bank.

Perfect for Meshtastic Projects
This board works flawlessly out of the box with Meshtastic firmware. The GPS lock is fast, and the battery life is impressive for a device this size.

Excellent range and stability
Tested this in an urban environment and the LoRa range exceeded my expectations. The OLED display is bright and easy to read outdoors.
Q: Can I use a standard 18650 battery with this board?
A: Absolutely. The board features a built-in charging circuit designed specifically for standard 3.7V 18650 Li-ion batteries.
Q: What voltage does the USB-C port provide for charging?
A: The USB-C port accepts standard 5V input for charging the connected battery and powering the device.
Q: Does this board come pre-flashed with Meshtastic firmware?
A: Yes, most units ship with the latest stable version of Meshtastic firmware pre-installed, ready to use immediately.
Q: Is this compatible with Arduino IDE?
A: Yes, since it uses the nRF52840, you can develop using the Arduino IDE by installing the appropriate nRF52 board package.
Q: Is the antenna included or do I need to buy it separately?
A: The board includes a small internal ceramic antenna, but for optimal range, we recommend connecting an external antenna via the IPEX connector (sold separately).
