I used a logic analyser to decode the serial protocol and a boost converter to power the ESP32 from the multimeter's batteries, resulting in a Wi-Fi multimeter that hosts its own web server. 🏷️ Tags #diy #electronics #esp32 #project #maker #hacking #multimeter #wifi #bluetooth #iot #reverseengineering #logic #analyzer #esp32project #teardown #serialprotocol #pulseview #aliexpress #jlpcb #webserver #tps61023
