WEMOS LOLIN D32 Pro

Regular price $18.95

The LOLIN D32 Pro uses the ESP32 Microcontroller with the ESP-WROVER chip, adding 4MB psRAM. This board also comes with I2C and TFT ports.

If you just wanted the plain ESP32-WROOM-32 chip version, we also have that here.

By default, the board comes with MicroPython firmware, and includes headers (requires soldering). For support for the 4MB psRAM via SPI, you can either download a pre-built binary to flash, or compile your own to allow a custom RAM configuration.

Of course, you can also program this board with Arduino.
