This ESP32 based WEMOS Lolin32 Lite compatible WiFi enabled Development Board comes with MicroPython Firmware (Interpreter) installed. 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).

This is a good ESP32 clone dev board that adds the ability to charge a LiPo battery as well as run off the battery; makes a great built-in UPS system for field-mounted sensors.

It worked. I did not smoke it like the previous one I received. Hint: Don't hook up 3.3 volts while the USB is connected to your computer.
