Learn about Zener diodes and build your own tester.
The battery checker uses a gen4-uLCD-28DT, which uses the Diablo16 Graphics LCD Processor.
The measured voltage is up to 60V, and the measured current is up to 30A. The device is based on the Renesas DA14585 SoC
This tutorial shows how to use the INA226 Voltmeter with a GC9A01 Display in Visuino to measure and display voltage in real time.
