Beetle ESP32 Microcontroller [Sewable]

This little beetle can be sewn into your wearables!

The Beetle-ESP32 is only 35 × 34 mm in size — a simplified version of the FireBeetle-ESP32, specially designed for electronic engineering fans and DIY lovers. It has large-scale gold-plated I/O ports that are easy to twist wire onto or sew directly into clothing without soldering.

Note: the holes are small, so you do need a thin needle. It can also be soldered with wires that you sew into your circuits.
