STC/IAP15W4K61S4 development board

Overview

The STC/IAP15W4K61S4 development board is a microcontroller development board based on the STC/IAP15W4K61S4-30I-PDIP40 main control core. It has an automatic cold start function, all IO pins are doubled, and the board has 5V and 3.3V power supplies. The USB to serial port uses the ch340G design and is compatible with CH340C. Installing CH340C can save the crystal oscillator and peripheral capacitors. The main control retains the external crystal oscillator circuit, and the ADC reference voltage is based on the 2.5V provided by TL431 as a reference. You can enable the external crystal oscillator according to personal needs. If not, you do not need to solder the crystal oscillator and peripheral devices.
