This is a simple GPIB interface design using an ESP32 board as main controller. It can (optionally but highly recommanded) use a couple of driver ICs (SN75160 and SN75161/162).
The design consist in 2 boards coupled together: one with the IEEE488 connector and driver ICs, and one with the Arduino or ESP32 board.
Doing so, the common GPIB board can be used with several Arduino/ESP32 boards.
