STC8H3K64S4 development board

Overview

STC8H3K64S4-LQFP48 development board
main control chip STC8H3K64S4-45I-LQFP48, all pins are doubled, vref reference voltage adopts TL431, reference input voltage of 2.5V, USB to serial port, based on CH340G design, compatible with CH340C, use CH340C, no need Welding crystal oscillator and peripheral devices, program burning method: adopt manual-free cold start automatic download method to realize one-click download of program. Anti-static ESD devices are added to the D+, D- and serial port 1 (P10, P11) lines, which can be welded according to personal needs. No welding will not affect the circuit. The board has 5V and 3.3V power supply interfaces and a physical button. Used to reset the microcontroller hardware.
