Compact and powerful
Don't let the size fool you; this little board packs a punch. The STM32F103 handles my multitasking logic without breaking a sweat. Highly recommended.

Great value STM32 board
Solid build quality from Du Yang Studio. The pinout is clearly labeled. Only minor issue is the documentation could be more detailed in English, but the schematic is clear enough.

Good board, fast shipping
Arrived quickly and well packaged. The USB-C port is a nice modern touch. Flashing firmware via SWD was instant. Would recommend for intermediate users.

Excellent for learning CAN bus
I bought this to learn about automotive communication protocols. It works flawlessly with Keil and STM32CubeIDE. The price point is unbeatable for these features.

Reliable for control systems
We used several of these for a small conveyor belt controller project. The stability over RS485 has been excellent even in a noisy electrical environment.

Perfect for industrial prototyping
The built-in RS485 and CAN interfaces saved me so much time. No need for external modules. The screw terminals are robust and easy to wire up for testing.
Q: What is the maximum baud rate supported on the RS485 interface?
A: The hardware UART supports standard high-speed baud rates up to 4.5 Mbps, though typical industrial RS485 applications usually run between 9600 and 115200 bps for reliability.
Q: Does this board support Arduino IDE?
A: Yes, the STM32F103 core is supported by the Arduino IDE using the STM32duino package. You can program it just like a standard Arduino board.
Q: Can I power this board directly from a 24V industrial supply?
A: No, the input voltage range is 5V to 12V. Connecting 24V directly may damage the onboard regulator. Please use a step-down converter if your source is 24V.
Q: Is an external debugger included in the package?
A: No, the board features an SWD header for debugging, but you will need to provide your own ST-Link V2 or compatible debugger separately.
Q: Are the CAN transceiver pins accessible via headers?
A: Yes, the CAN_TX and CAN_RX lines are broken out to standard 2.54mm pin headers in addition to the screw terminals, allowing for flexible connection options.
