Reliable development board
I've bought five of these for my students. Consistent quality and the SWD interface makes debugging easy. Highly recommended.

Works but needs care
One of the capacitors looked slightly loose upon arrival, but it functions. Just be careful when handling the pins.

Perfect for learning ARM
Great little board. Works straight out of the box with the Arduino IDE after installing the STM32 package. Pin headers were straight and soldering was clean.

Good value, minor issue
Board works well for my robotics project. Had to update the bootloader via ST-Link initially, but otherwise functions as expected.

Compact and powerful
Love the form factor. Fits perfectly into my custom enclosure. Voltage regulation seems stable during testing.
Q: Is this compatible with Arduino IDE?
A: Yes, you can use the Arduino IDE by installing the STM32duino bootloader and core support.
Q: Can I power this with 5V?
A: Yes, you can supply 5V to the VIN pin, the onboard regulator will step it down to 3.3V.
Q: Is the APM32 chip identical to STM32?
A: Yes, the APM32 is pin-to-pin compatible and functionally equivalent for most standard applications.
Q: Does it come with pin headers soldered?
A: This version typically comes with pin headers included but unsoldered for flexible mounting options.
Q: What debugger do you recommend?
A: We recommend using an ST-Link V2 debugger for the SWD interface for best compatibility.
