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.

ESP32 Lolin D32 Pro

I finally got around to testing this device. I bought it to try out micropython as I have been using C and the Arduino IDE for some time and wanted to try another language.

I used the micropython Thonny IDE and loaded the latest CH340 serial driver and everything worked like a charm.

It was my first purchase from SmallDevices and wont be my last. Much better experience than buying from the big Chinese websites and much faster delivery!

Great product and very efficient service

I purchased the Lolin D32 Pro. It is a great little board. My project is still a work in progress. But so far everything is working nicely, including utilsation of the deep-sleep mode to extend battery life when power is not connected.The device was shipped quickly and efficiently. And the price was very competitive for an Australian supplier. No doubt I could have got it cheaper in China, but this was delivered in a couple days. Great value. Will certainly look to SmallDevices for other gear.

Very satisfied with product and service

I bought the Lolin D32 ESP32 and Lolin D32 Pro ESP32 boards because they have very low deep-sleep current, so it is ideal for projects that need extended battery life. I was able to get it to work very easily in Arduino IDE. The order was Shipped by SmallDevices very quickly after the order was placed. Thank you!
