Source code and KiCad PCB design files for AR488 with Arduino Mega 2560

This board is capable to communicate IEEE-488 protocol between the instrument and a PC. The communication can be with a USB cable or battery-power Bluetooth communication. The firmware is from https://github.com/Twilight-Logic/AR488. Thanks to his help for this hardware project.

You can find the chips here: SN75160BN and SN75161BN.

The GPIB connector I use: 112-024-213R001. Please note that this is a female connector, so you will need a GPIB male-male cable.
