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.
