Sun2UsbAdapter
Adapter for using Sun Keyboards (4/5/6) as USB devices, with macro support, using the excellent Alexander Vollschwitz's suniversal adapter. This repo includes the specific pinout for the OEM 8pin connector, and how to wire it to the arduino pro micro (clone).
Parts
Cheap Ebay 8Pin MiniDin, model N8Pin (3,60€ / 5 units).
Ardunio Micro Clone Any model will work.
Connector Pinout and wiring
After reverse engineer the wiring, I get the following table:
| Connector PIN | Base PIN | Wiring color | Description | Arduino PIN |
|---|---|---|---|---|
| 1 | E | Red | VCC +5V | VCC |
| 2 | F | White/Black | - | |
| 3 | H | Green | From Keyboard | D10 (RX) |
| 4 | A | White | To Keyboard | D9 (TX) |
| 5 | G | Black | From Mouse | |
| 6 | D | Yellow | VCC +5V | |
| 7 | B | Yellow/Black | GND | GND |
| 8 | C | Grey | GND |
Software Install
See the guide on Alexander Vollschwitz's suniversal adapter. Just download the sketch, select your board (arduino micro or leonardo) and download it. Just edit the
config.h file and select your options (mine where don't use mouse, and don't debug)
