Hi! I made a development board based on the ESP32 for wearable and textile projects. The reason I created this is that, on the one hand, current round development boards like Lilypad lack wireless capabilities, which are very important for wearable projects; on the other hand, sewing is quite troublesome, especially when issues are discovered after the sewing is done.

So, in making this development board, I used the ESP32-PICO-D4 as the core for performance reasons, and I also included other sensors on board; to solve the quick connection and fixing problems, I found buttons that fit in size to create button connection wires, and I embedded magnets on the PCB, which, together with corresponding magnetic fixing pieces, can secure the PCB to clothing like a sandwich.
