TIAO GBoard / GIMX Adapter
For system connection diagram as GIMX adapter, please refer to TIAO GIMX System Connection Diagram. For loading the firmware, please refer to How to Install GIMX Firmware on TIAO GBoard/GIMX Adapter
The TIAO GBoard / GIMX adapter is a combined all in one board for serial and AVR development. It also provides jumper connections for easy and quick GIMX connectoion (to be used as a GIMX Game Input MultipleXer or Game Input MatriX adapter. For more information on GIMX, please check it out here.
The TIAO GBoard/GIMX Adapter features:
- All in one board contains USB to COM adapter and ATMEVA32U4 for AVR development.
- Bootloader is installed on the ATMEGA32U4, so you don't need a programmer to load the firmware.
- Quick connection jumpers to convert the GBoard to a GIMX adapter
- RX/TX LED, enable LEDs or use the pins for IO ports
