Wemos S2 Mini

Cheap purple ESP32-S2 board: just enough GPIO and speed to drive a display for pocket change.

Good to know

  • Native USB only – if the port "disappears", hold the GPIO0 button and tap RST for download mode.
  • Strapping: GPIO0, 45, 46 – leave them alone at boot.
  • Built-in LED on GPIO15.
  • No Bluetooth (S2), and every pin is 3.3V.
