From the project
An rp2040-based acquisition board for pulse-echo ultrasound
The pic0rick is a very central board for an ultrasound pulse-echo system. It is composed of a main board, based on the RP2040 (or RP2350) 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…
