pic0rick

Description

The pic0rick is a very central board for an ultrasound pulse-echo system. It is composed of a main board, based on the famous rp2040 and easy to solder SMD, to which a single, and a double PMOD connector can connect to addons:
- The main board is equipped with a 60Msps, 10bit ADC. Front end is protected against high-voltage pulses, and features a proven time-gain compensation system consisting in a AD8331 (7.5 dB to 55.5dB) with a controlling (MCP4812) SPI DAC.
- The single PMOD connector can plug to the Pulser board, which can be equipped with a simple +-25V generation board. Together, they generate the pulse on behalf of the pic0rick main board. The setup can generate three-level pulses ( with a pair of MD1210 + TC6320 ).
- The double PMOD connector can be used for virtually anything. The current code allows for a VGA to be connected, which displays acquisitions from the board.

I've also been recently working on some more work..
- A pHAT to get a fast ADC running
- A FT600Q board, where I try connecting a FT600 directly to a 100Msps ADC
- An SDR board, based on the MSI001 / MSI2500 combo
Now seems to work!

After some soldering (thanks OSHPark, again ;) )... with some 2-layer and 4-layer boards (you know which is which, you recognize the "after dark" style)..

The three boards once assembled look like this

Example of acquisitions

This is pretty much on part with the un0rick or the lit3rick boards.. so .. success !!
