Compact powerhouse
Using this for a low-power sensor node project. The sleep modes work as expected, and the compact size allowed me to fit it into a very tight housing. Fast shipping too!

Good price-to-performance ratio
For the price, you cannot beat the specs. The Cortex-M4 core handles floating-point math efficiently. I deducted one star because the soldering pads are quite small for beginners.

Great learning tool
Bought this for my university embedded systems course. It works well with STM32CubeIDE. Only minor issue is the pinout diagram could be clearer in the documentation, but otherwise excellent value.

Robust and reliable
We bought ten of these for our makerspace. They have survived multiple student wiring errors thanks to decent protection. The form factor fits perfectly into our custom enclosures.

Genuine chip confirmed
I was worried about counterfeit chips, but this one is definitely original. Readout confirms the full 256KB flash and runs at stable 84MHz. Highly recommended for serious projects.

Perfect for custom flight controllers
This board is incredibly small yet powerful. I used it to build a custom drone flight controller and the performance is flawless. The USB download feature makes flashing firmware very convenient.
Q: Does this board support Arduino IDE?
A: Yes, this board can be programmed using the Arduino IDE by installing the appropriate STM32 board package (e.g., STM32duino). You may need to select the generic STM32F401RC variant.
Q: Is a JTAG/SWD programmer included?
A: No, a separate programmer is not included. However, this board features a built-in USB bootloader, allowing you to upload code directly via the Micro USB cable without an external ST-Link programmer for most use cases.
Q: What is the input voltage range for the VIN pin?
A: The onboard regulator typically accepts an input voltage between 3.6V and 10V on the VIN pin, which is then regulated down to 3.3V for the MCU. Please check the specific schematic provided in the download section for exact limits.
Q: Can I use this for a Betaflight drone setup?
A: Yes, many users successfully run Betaflight on this board. Since it uses the STM32F401RCT6, it is compatible with many flight controller targets. You will need to configure the pins according to your specific build.
Q: Does it come with header pins pre-soldered?
A: No, the board is shipped without header pins soldered to allow for flexible mounting options and lower profile installation. You will need to solder your own headers or wires.
