Using apf27 for a custom hobbyist project is very expensive. Because it's necessary to buy a big and expensive extension card named APF27-dev (152€ min) with the base module apf27 (127€ min), very few hobbyist use it.
The aim of this project is to make a little PCB with minimum extension devices to have an extension card that cost 50€ max. The apf27dev PCB design will be reused; surface will be divided by 2 to speed development.
Maximum of I/Os and ports must be available on light-apf27dev :
- 1 USB OTG (Only host ar real OTG TBD)
- 1 ethernet
Header that correspond on apf27Dev to :
- Wireless connector J8 and J9
- FPGA connector J19 and J20
- User extension interface J22
- 1 power circuit
- 1 reset button
- 3-pin header for debug uart
And maybe but not sure:
- SD connector
- second USB host
