What is it?

The ESP32-S2 mini is a top microcontroller (MCU) with many possibilities:

• Type-C USB
• 4MB Flash
• 2MB PSRAM
• 27x IO
• ADC, DAC, I2C, SPI, UART, USB OTG
• Compatible with LOLIN D1 mini shields
• Compatible with MicroPython, Arduino, PlatformIO, CircuitPython and ESP-IDF

The 'blink' program is pre-installed, so the correct functioning of the board can be checked immediately by connecting an USB-C power supply. The 32 header pins are already soldered.

Compatible with Wemos / Lolin ESP32-S2 hardware and software in the Arduino IDE and PlatformIO.

Why did you make it?

I made this ESP32-S2 mini myself because I needed it for a customer and also because all of the 60(!) ESP32-S2 mini's (likely clones) I ordered at 4 different shops at Aliexpress did not work. This ESP32-S2 mini works, guaranteed! It has a genuine Espressif chip and is professionally (machine) made in Hong Kong.

What makes it special?

It does work :) and it is good quality.
