Because the hardware uses an Atmel AVR microcontroller (usually an or similar, though some clones use non-standard chips), it can be flashed with the open-source code. There are two main branches of this project maintained by the community:

: Successfully identifies Darlington transistors and sensitive SCRs/Triacs that used to trip up the old version. Advanced Features

Most LCR-T7 units require an external programmer (like a CH341A or an Arduino as ISP).

Refined algorithms for ESR and capacitance.
