Perfect for Blue Bridge Prep
This board matches the competition requirements exactly. All peripherals work out of the box, and the example code provided helped me understand the register-level programming quickly.

Great hardware, documentation could be better
The build quality is solid and the STM32RBT6 chip is powerful enough for complex projects. However, some of the English translations in the manual are a bit rough. Still highly recommended for students.

Standard competition platform
If you are participating in the Blue Bridge Cup, this is the mandatory platform. It arrived well-packaged and all sensors were calibrated correctly. Very satisfied with the purchase.

Robust design for industrial training
We use these in our university lab for industrial control courses. They withstand frequent plugging and unplugging. The only minor issue is the USB cable included feels a bit flimsy.

Excellent value for learning embedded systems
I bought this to learn ARM Cortex-M4 architecture. The integrated ST-Link saves money on extra debuggers. The joystick and OLED screen make it fun to create interactive projects.

Fast shipping and works perfectly
Received the board in three days. Loaded the first demo project within an hour using Keil MDK. The pinout diagram on the back of the board is very helpful for wiring external circuits.
Q: Are the schematic diagrams available for download?
A: Yes, detailed schematic diagrams and datasheets for the peripheral components are available in the 'Downloads' section of our product page or upon request via email.
Q: Can I power this board using a standard phone charger?
A: Yes, you can power the board via the USB Type-C port using any standard 5V USB charger or computer USB port. It also supports external 5V input through the header pins.
Q: Is this board compatible with the standard Blue Bridge Cup competition rules for 2024?
A: Yes, the CT117E with the STM32RBT6 microcontroller is the official standard platform designated for the recent Blue Bridge Cup Embedded Software Design competitions.
Q: Does this come with pre-installed firmware or do I need to flash it myself?
A: The board comes with a basic demo firmware pre-flashed to test hardware functionality. However, for development, you will need to install your own IDE (like Keil or IAR) and flash your custom code.
Q: What software environments are supported for programming this board?
A: This board supports major ARM development environments including Keil MDK-ARM, IAR Embedded Workbench, and GCC-based toolchains like STM32CubeIDE or PlatformIO.
