TopHAT modules are secondary HAT (Hardware attached on top) modules that mount on the MaplePi and MapleDroid FPGA modules to provide additional functionality.
These modules are concepts only at this stage, but further work will be done when time and demand permits.
- Additional port with Digital I/O
- Quad port adder with Digital I/O
- TKR901 repeater PLL interface
- C4FM transceiver for 400 MHz MMDVM hotspots using ADF7201 chip
- SDR transceiver 900MHz and 2.4GHz using AT86RF215 OFDM chip
They are described further on their own pages.
