TIAO GBoard / GIMX Adapter
For system connection diagram as GIMX adapter, please refer to TIAO GIMX System Connection Diagram.
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
