While older models used the Atmel ATmega328P microcontroller, newer iterations of the LCR-T7 often use alternative or clone microcontrollers due to chip shortages and cost-cutting measures. Common Microcontrollers inside the LCR-T7:
If you want the absolute latest , look for compiled for the 644PA chip. This version includes: lcr t7 firmware
You cannot update the LCR-T7 firmware via USB. It requires direct access to the ATmega328P chip. lcr t7 firmware
