N32G430C8L7 core board

Overview

The N32G430 core board
is made according to the layout of BluePill, which is a circle larger than BluePill.
It uses the N32G430C8L7 chip, which has three more IOs than STM32, and the extra IOs are placed next to SWD.
Version two uses xc6206 LDO to power the ADC, etc.
Version three uses a voltage reference to power the ADC, etc.
The hex file is a lighting program that uses an external 8Mhz crystal oscillator to test the chip operation.
The production cost is ￥9.2, and all are front components for easy patching. There are three versions of

precautions
. The first version has some minor problems, but it does not affect the use.
Versions two and three use LDO and voltage reference as the power supply and reference voltage for the ADC.
There is a 0R resistor as a switch to switch the ADC power supply. After welding, it shares 3v3 with the MCU.
