ESP8266 adapter


The adapter method places the ESP8266 very close to the TiVo5725 scaler chip, which exposes it to electromagnetic interference.
As a result, the ESP8266 can have issues with its WiFi, resulting in limited access to the web interface.
As such, I don't recommend using this adapter method.
Instead, place the ESP8266 module right next to the GBS 8200 board, near the I2C connection headers.

This is a method of mating a GBS board with a common ESP8266 development board, using a socket to attach to the original MCU.
It provides all the required signals for the ESP8266 to take over control of the scaler.
