Simple interface to run my Anet A8 using ESP3D and an ESP-01 module. A TTL gate keeps startup serial data out of the printer. Requires removing 2 zero ohm resistors and installing a 6 pin header on the Anet controller in the BLE/USB position. You will also need to add code to the ESP3D sketch’s setup() function to set GPIO 0 as an output and write a logic LOW to that pin in order to enable transmit data to go out of the ESP-01 to the printer. This board should plug in to the connector next to the LCD connector. Power should be taken from the 12v board power (or a separate wall-wart might be used). I wasn’t sure if the on-board regulators would handle the extra load of an ESP8266.
Later edit, after getting boards built and tested: Going from 12v to 3.3v generates a lot of heat. I recommend to either use an external 5v supply (not 12v) or replace the regulator at U1 with a Recom R-78E3.3-1.0 (though the pinout will be different!! Watch how you wire it!)
