Wireless LCD Streaming for the ANENG AN870 Multimeter
2 min read
A project streams the ANENG AN870 multimeter's LCD display wirelessly by tapping its multiplexed LCD signals. An RP2040 Zero and HC-12 433 MHz transceiver inside the meter send data to an ESP32-C3 receiver, making the display available via WiFi for OBS overlay. A custom PCB reads the LCD segment lines.
