stm32g030k6t6 is a pretty good-looking development board

A very normal stm32g030k6t6 development board (verified).
Because a friend wanted to get involved, I honestly made a general stm32 development board for the first time (previous ones were all for specific purposes), using Xiaozhengtai The dcdc power supply solution (mt3520b), onboard ch340c for serial port download, onboard ws2812 if you want to use spi or pwm driver, you can use
rev0
to use dcdc power supply
. The serial port module has no isolation. If you use pins for uart, there may be some problems (
VCC is not led out, If other power supply solutions cannot be used,
please use the second drawing if you need direct proofing. The first drawing is only for secondary modification.
 
 
The picture shows
 
the serial port download tutorial.
Different series of stm chips have different serial port download methods. For details, please see the official RM manual. This is only a teaching warning for the g0 series
: you must follow the tutorial for the first time, otherwise subsequent serial port downloads will no longer be available. You can only re-enable the serial port download function through various downloaders
. First, connect the development board via USB and open STM32CubeProgrammer software, select the device on the right (if not found, just click the refresh button), click connect
, then uncheck the nBOOT_SEL option in OB, and click apply to confirm,
then select the firmware in the download page to download, and you will be happy It's fun
