- The pic0rick is a microcontroller-based board replacing FPGA designs in the un0rick family, offering similar ultrasound acquisition performance with lower cost and complexity.
- It features an RP2040/RP2350 microcontroller, a 60 Msps 10-bit ADC, an AD8331 TGC amplifier, and uses PIO state machines for precise timing instead of an FPGA.
- The system is modular with three boards: main board, pulser board, and HV board, and supports PMOD extensions like VGA output, MUX, and PSRAM.
- Compared to legacy boards (un0rick, lit3rick), it is cheaper, easier to program in C/C++, and recommended for new projects, education, and fast prototyping.
- All hardware and firmware are open source, available on GitHub and Tindie, with licenses including TAPR OHL for hardware, GPL for software, and CC BY-SA 3.0 for documentation.
