Reliable for industrial prototyping

Used this for a quick proof-of-concept before moving to a custom PCB. The stability at 72MHz is impressive, and the peripheral support (ADC, UART, SPI) is robust.

Solid hardware, minor documentation gaps

The board itself is high quality with good soldering. However, the included PDF manual was a bit sparse. I had to look up the datasheet online for specific register details, but that is standard for these chips.

Fast shipping and genuine chip

I was worried about getting a clone, but this appears to be a genuine STMicroelectronics chip based on the marking and performance. It handled my PWM motor control test without heating up.

Bought 10 for our science club

We purchased a bulk pack for our high school robotics team. Every single board worked out of the box. The compact size makes it easy to integrate into small robot chassis.

Great board, needs external programmer

Just a reminder for newbies: this board does not have an onboard USB-to-Serial converter. You will need an ST-Link V2 or similar debugger to program it. Once set up, it runs perfectly.

Perfect for beginners and pros alike

This board is exactly what I needed for my university project. The pinout is clearly labeled, and it works flawlessly with the Arduino IDE using the STM32 core. Great value for the price.

5 FAQ

Q: Does the package include headers pre-soldered?

A: This depends on the specific option selected at checkout. Our standard kit usually comes with loose header pins for you to solder, allowing flexibility for breadboard or direct wiring usage.

Q: Is this compatible with the Arduino IDE?

A: Yes, you can use the Arduino IDE by installing the STM32duino board package via the Board Manager. Select the 'Generic STM32F1 series' and choose the correct variant.

Q: Does this board come with a USB cable for programming?

A: No, this is a minimum system board and does not include an onboard USB interface. You will need a separate ST-Link V2 programmer to upload code.

Q: Can I use this for 5V logic sensors?

A: The GPIO pins are 5V tolerant in input mode, but they output 3.3V logic. For 5V output sensors, you may need a logic level shifter to ensure reliable communication.

Q: What is the maximum input voltage tolerance for the VIN pin?

A: While the board operates at 3.3V, the VIN pin typically accepts 5V if your specific module revision includes a regulator. However, for safety, we recommend powering directly via the 3.3V pin if using an external regulated supply.
