Beginner friendly
As someone new to ARM development, this board was easy to set up. Plenty of tutorials available online specifically for the F103 series. Very satisfied.

Reliable and fast
I've used several STM32 boards, and this DRG version is very stable. The 72MHz clock speed handles my sensor data logging without any lag. Highly recommended for prototyping.

Solid performance
Works well with FreeRTOS. The flash memory size is adequate for most medium-complexity applications. Shipping was fast too.

Perfect for embedded projects
This core board is exactly what I needed for my robotics project. The pinout is standard, and it works flawlessly with the STM32CubeIDE. Great value for the price.

Great minimal system board
No unnecessary components cluttering the board. Just the MCU and essential passives. Makes it easy to integrate into custom PCB designs later.

Good learning tool
Bought this for my university microcontroller course. It's compact and easy to breadboard. Only wish it came with a detailed pinout diagram in the box, but the online docs are sufficient.
Q: Can I power this directly from a 9V battery?
A: It is not recommended to connect 9V directly to the 5V input pin as it may exceed the regulator's maximum input voltage. Please use a 5V source or a regulated supply between 3.3V and 5V depending on your connection point.
Q: Does this board come with a built-in programmer?
A: No, this is a core board and does not include an onboard ST-Link programmer. You will need an external ST-Link V2 or similar debugger to program the device.
Q: What is the current limit for the 3.3V output pin?
A: The onboard regulator can typically supply up to 200mA, but we recommend keeping the load under 100mA for stability when powering external peripherals.
Q: Does it support floating point operations?
A: The STM32F103RCT6 uses a Cortex-M3 core which does not have a hardware Floating Point Unit (FPU). Floating point math is handled in software, which is slower than hardware acceleration.
Q: Is this compatible with Arduino IDE?
A: Yes, you can use this board with the Arduino IDE by installing the appropriate STM32 board support package (BSP) via the Board Manager.
