# Connecting Anet A8 to ESP Boards ## Anet boards up to v1.5 ### Step 1 You will also have to unsolder the resistors R52 and R53 – they are zero ohm resistors, and serve no other purpose than connecting the atmega chip directly to the onboard USB to UART converter (the CH340 chip). Do it VERY careful – you don’t want to damage your board. If you don’t feel confident – don’t do it. ![R52 and R53 position](http://lokspace.eu/wp-content/uploads/2017/01/image08-300x300.jpg) ### Step 2 Now prepare the printer’s motherboard. It requires a simple modification, that does not interfere with it’s operation afterwards – just solder 3 pin x 2 row male header on J8, and add 2 jumpers (or jumper wires) as shown on the picture: ![Header and jumper position](http://lokspace.eu/wp-content/uploads/2017/01/image05-300x300.jpg) ### Step 3 Connect the ESP to J3 repsecting pinout ![J3 connector pinout](http://lokspace.eu/wp-content/uploads/2017/01/image00-232x300.jpg) |ESP|J3| |:---:|:---:| |Tx|Rx| |Rx|Tx| |GND|GND| |VCC|3.3V| |CH_PD|3.3V| For more Info check ## For connecting version 1.7 Anet boards Unlike older boards this board does not require you to remove any resistors. You will have to solder two wires from number 9 and number 10 its recommender to connect these to pin 1 and 2 of J3 connector. ![ANET A8 v1.7 board](https://raw.githubusercontent.com/wiki/luc-github/ESP3D/images/Anet/board.jpg)
