LQFP-48 packaged STM32/GD32/AT32 microcontroller chips, including but not limited to the following models:

• STM32F103C8T6
• STM32F030C8T6
• GD32F103C8T6
• GD32F130C8T6
• GD32F150C8T6
• GD32F330C8T6
• GD32F303CCT6
• GD32E103C8T6
• GD32E230C8T6
• GD32VF103C8T6
• AT32F415CBT7
• AT32F413CBT7
• AT32F421C8T7
• AT32F425C8T7

The pin arrangements of these models are compatible and can all use this development board.

Compared with other versions on the market, the improvements are as follows:

• USB replaced with direct plug MicroUSB, strong and durable
• The BOOT0 selection is changed to a button. Press and hold BOOT0 and then press NRST to enter the built-in Bootloader.
• The 32.768 crystal oscillator is replaced with a 3×8 package and is not soldered by default.
• The VBAT pin uses a 0R resistor to connect to the onboard 3.3V power supply
• The SWD interface sequence is changed to CLK, DIO, GND, 3V3
