CTR2-Micro Firmware Update
v1.08.00 - July 4, 2026

This zip file contains a single firmware .BIN file that is used to program CTR2-Micro, in addition to the Micro's Operation Manual.

To flash this .BIN file to your device, extract it into a folder then use the instructions in the Update Firmware section in the CTR2-Micro Operation Manual. I highly recommend using the ESPConnect option to flash your CTR2-Micro.
