* Fits Wemos Lolin D32 (not Lolin32, Lolin D32 pro or Lolin 32 lite!)
* Outer diameter: 53 x 81mm
* JST-PH 2.0-connectors for buttons, rotary encoder, Neopixel, RFID and reset (not 2.54mm pitch!)
* JST-PH 2.0-connectors for buttons (2 pins), rotary encoder (5 pins), Neopixel (3 pins), RFID (6 pins) and reset (2 pins). Please note: all of them are NOT 2.54mm pitch but 2.0mm!)
* 2.54mm-connectors for MAX98357a and uSD-card-reader. In contrast to my pictures: better solder them directly onto the PCB without having a female-connector (as socket) in between. In turned out that especially plugging MAX98357a into a female connector can lead to connectivity-issues!
* Mosfet-circuit that switches off MAX98357a, Neopixel, headphone-pcb and uSD-card-reader automatically when deepsleep is active
* All peripherals are solely driven at 3.3V! Keep this especially in mind when choosing uSD-reader. If in doubts use one without voltage-regulator (link below).
