The LCR-T7 multi-function tester uses open-source firmware based on the AVR Transistor Tester
The is a popular, low-cost multi-function tester. It is an evolution of the original "Mega328" transistor tester design, capable of measuring resistors, capacitors, inductors, diodes, transistors, MOSFETs, and even thyristors. It features a color display and a rechargeable battery, making it a staple for hobbyists. lcr t7 firmware link
The EEVblog community has massive threads dedicated to "TC-1" and "T7" clones. Users often share custom-compiled firmware optimized for the T7's specific color screen and pin layout. Requirements for Flashing The EEVblog community has massive threads dedicated to
