LOLIN32 Lite ESP32 MicroPython, Battery Charger

ESP32-based WEMOS Lolin32 Lite ESP32 MicroPython compatible WiFi enabled Development Board. All you need to program it is a USB or serial (RX/TX) connection to the host (computer) and a terminal program. Programming is a lot simpler than Arduino (based on C) and can be done without the need for a special development environment (like Arduino IDE or AVR Studio).

Fits our Universal Screw Terminal Adapter (SKU 26162)

* - not all of the interface pins of the ESP32 MicroPython module are accessible through the development board
* - this is a 3.3V device, make sure you use level shifter to connect I/O ports to higher logic level like 5V
