Is anyone thinking about building a Radio/Repeater Cape for the BBB?
ie: a URI or RB-USB-RIM re-spun as a cape
I would be interested in a cape with these attributes.
Cape Form Factor which attaches to BBB headers (daughter board)
-12 VDC power input (power pole?) which then regulates 5 VDC for BBB supply.
-Reverse polarity protection on power input
-USB interface to BBB via usb cable (because USB is not on header)
-CM119 audio chip
-buffers for more GPIOs than URI/RB-USB-RIM
-Similar features as RB-USB-RIM
-USB/Host Heartbeat with capability to trigger in cabinet repeat in case
of BBB fail
Longer term, with different audio drivers, the BBB has I2C audio driving
the HDMI interface.
A repeater cape could have an I2C Audio DAC as an alternative to USB Audio.
Currently available analog Audio Capes for BBB take this approach.
