At present core boaed onboard Flash,LED,NRST and BOOT0 keys,Reserved serial interface of LDC,Need
0.8mm wire the connection
Commander have used
0.8mm
BTB_2x20P,Not connected to Expansion
Download program can use reserved SW bonding pad to connectedCable
orTest probe
Download program
Commander
none 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 one
CP2102
USB can be connected for serial communication.STM32G431CBU6 supportUCPD
so 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 R
0402
bonding pad,it's recommended to weld pull-down R for CC1 and CC2🔌
Expansion the type of embedded stud is
M2x4x5.0x2.5x1.0
,BTB combined height is5.0mm
I/O Pin header is 2.54mmSMT
.Optionally add baseplate for Expansion,Baseplate fileeffect maps
⚠️ Please read the PCB Engineering Instructions pdf file- 👓The whole project uses a two-layer process. If you don't have kicad installed, you can directly view Bom for welding. Gerber files are also in HDK
