About the PMOD2VGA PCB

PMOD2VGA is an open source PCB design by kelu124, published on GitHub. It is a 2-layer board measuring 47.3 × 16.3 mm, with 7 components from 4 distinct parts.

By type, the board carries 6 resistors and 1 connector.

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)…

PMOD2VGA: common questions

How big is the PMOD2VGA PCB?

The PMOD2VGA measures 47.3 × 16.3 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the PMOD2VGA?

7 components, from 4 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the PMOD2VGA design files?

From the kelu124/oshmri repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.

Can I use the PMOD2VGA design in my own project?

The repository has no license, so all rights stay with kelu124. Use it as a reference, and ask the author before reusing the design.
