STC51-NUCLEO

Overview

This is an STC offline downloader that integrates STC8A8K's strongest 51 microcontroller and 18650 lithium battery power supply. It can realize offline downloading of external STC51 microcontrollers, supply power to external target boards, and can also use the STC8A8K on the board to simulate 51 microcontrollers in real time. . The principle is introduced in several other open source projects: STC51 MCU offline downloader [https://diy.szlcsc.com/p/583703056a/stc51-dan-pian-ji-tuo-ji-xia-zai-qi ](https://diy.szlcsc.com/p/583703056a/stc51-dan-pian-ji-tuo-ji-xia-zai-qi) 18650 boost 5V board [https://maker.lceda.cn/ p/583703056a/18650-sheng-ya5v-ban](https://maker.lceda.cn/p/583703056a/18650-sheng-ya5v-ban) STC8A8K microcontroller emulator board [https://maker.lceda.cn /p/583703056a/stc8a8k-dan-pian-ji-ban](https://maker.lceda.cn/p/583703056a/stc8a8k-dan-pian-ji-ban) PCB soldering products and empty boards![New version of soldering Rear side.jpg]
