The SparkFun Thing Plus STM32 provides you with an economical and easy-to-use development platform if you're needing more power with a minimal working space.

The STM32 Thing Plus provides a 3.3V regulator and LiPo charger as well as 16MB of Flash and MicroSD slot for expandable memory.

This Thing comes flashed with the DFU bootloader, and to make the Thing Plus even easier to use, a few pins have been moved around to make the board Feather compatible. In addition, it utilizes the handy Qwiic Connect System which means no soldering or shields are required to connect it to the rest of your system!

Customer Reviews

Disappointing compared with Sparkfun ESP32 Thing Plus

Again, I was looking for more program memory, but I had so much difficulty programming with Arduino IDE and it has fewer GPIO pins. It also had a USB-C socket which I didn't have handy.
