One of our in-house breakout boards designed for the Ra LoRa series of Ai-Thinker modules. This board features an original Ai-Thinker Ra-02 module, 2.54mm pitch breakout pins, a 50-Ohm antenna trace, and two M2 mounting holes just in case.
We are continuously looking to update and improve our designs, and we’d love to get your feedback on this board – please let us know what you think through any of our available contact channels.
