• This project used STM32G431 to master chip.A complete board to be made up of Commaner+Expansion

STM32G431CBU6 Core Board

Top	Bottom

At present core boaed onboard Flash,LED,NRST and BOOT0 keys,Reserved serial interface of LDC,Need0.8mm wire the connection

Commander have used 0.8mmBTB_2x20P，Not connected to ExpansionDownload program can use reserved SW bonding pad to connected CableorTest probeDownload program

Commandernone the LDO and DC-DC to buck,to the extent that core board power only give3.3V❗ ❗ ❗

• 1 USB support PD
• 1 USART to USB port
• 1 IMU(BMI270)
• 1 40P header

Expansion have oneCP2102USB can be connected for serial communication.STM32G431CBU6 support UCPDso the USB plug support PD and have one DC-DC buck module⚡

Consider that newbies may be less likely to use the STM32's built-in USB hardware controls,so i reserved USB_D+ pull-up R CC1,CC2 pull-down R0402bonding pad,it's recommended to weld pull-down R for CC1 and CC2🔌

Expansion the type of embedded stud isM2x4x5.0x2.5x1.0,BTB combined height is5.0mm I/O Pin header is 2.54mmSMT.Optionally add baseplate for Expansion,Baseplate fileeffect maps
