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

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. There's a section for both the EspressIF Flash Download tool and a section describing how to use the script file.

You can download the Flash Download Tools here: https://www.espressif.com/en/support/download/other-tools 

The CTR2-Micro_install.sh file is a script that you can use to install the firmware on your CTR2-Micro without the need of the EspressIF Flash Download tool. This file is most useful on Linux and Mac PC.
