The LoLin32 Lite Wemos is a more compact version of the LoLin32 which has been very often cloned by many other chinese development board manufacturers. It is more compact (about 45x22mm) but it provides the I/O assemblies of the ESP32. Two 13-pin connectors connect 21x I/O (3V3 operation), 1x 3V3, 1x GND and the EN/VP/VN pins. The LiPo battery connector type JST XH2-2.54mm is always present. It is now positioned in the axis of the card next to the RESET button.
It has a corrected version of the Espressive SoC, the ESP32-DOWD6Q 28017 (marked as Rev.1). It comes with pre-installed micropython firmware but you can run Arduino code or Lua programs as well.
