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-01S module, 2.54mm pitch breakout pins, a 50-Ohm antenna trace, and a single M2 mounting hole 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.
