From the project
OpenSourceHardware - going to MRI
1 dual PMOD, 12ADCbits+1clk + 1SPI (without MISO): based on the AD8331+ADC+DAC from https://github.com/kelu124/lit3rick/ (altium source in hardware folder) . Connector in: SMA, with MD0100 to protect. Possible elements: AD8331 ADC: AD9629BCPZ-65: 12bits, DAC: MCP4812-E/MS
Only logic through PMOD: positivepulse, negativepulse, damp. Expose remaining IOs on a 2.54" rail on the PMOD board (with 3.3V and GND as well) External GPIOs for +HV, -HV, GND. Internal : Positive: 3.3V -> 5V booster ; Negative: -5V rail for example (not mandatory if simpler exists)…
