This is an ESP32 development board made using the ESP32-C3-MINI Chip. It has features like lipo battery charging and programming through computer. This looks simple but i had spent approximately 13 hour to make this dev board myself. It hs tp4056 ic inbuilt for charging and esd diodes for protection. The battery could be even charged while programming the devboard because there are diodes to prevent backflow of the current. This was fully developed by me with the help of kicad.
