A single-design board going up to 64Msps, with a 2000 lines capacity, will be made available soon. Don't hesitate to drop me a message if you are curious.

Who doesn't need a quick and dirty ADC pHAT for her/his pi, especially these small wireless marvels? I know I need one, for trigger-based, burst action.
It's a ADC pHAT ... 2x ADC interleaved.
Testing the module with the signal emulator module, which yields a signal at 1.9MHz, it well seen at 1.9MHz, with a sampling speed equal to two times this freq, ie 24Msps ! See the results here.
The two interleaved ADCs are connected to the GPIOs of the ADC.
On the clock generated by GPIO4, one ADC samples and extracts 9 bits of info, the other half a cycle later, again on 9 bits. This info is extracted through a /dev/ device, managed by a kernel module.
I needed a fast ADC for ultrasound imaging -- full doc here.
Nothing similar had been done so far for the Raspberry Pi.
See the quickstart guide beforehand =)
