STC8A8K64S4A12-LQFP-48 core board

Overview

STC8A8K64S4A12-LQFP-48 core board, USB online automatic downloader, STC15W4K58S4 core board, with simulation function, can be used as the minimum system board, or the board can be broken to make the minimum system board and automatic downloader! I did this because I didn't want to have to toggle the switch to cold start the download, which is too annoying.

I won't introduce the principle of the online download circuit anymore, you can refer to this link:

picture shows the STC8A8K64S4 core board:
the TL431 regulator is used as the voltage reference, and the circuit is designed for high-precision reference.
