About the PICO ADC TEST PCB

PICO ADC TEST is an open source RP2040/RP2350 PCB design by kelu124, published on GitHub under the TAPR-OHL-1.0 license. It is a 4-layer board measuring 85 × 54 mm, with 55 components from 24 distinct parts.

Its main chip is the Pico, from the RP2040/RP2350 family. Other key parts include the ADC10065CIMT/NOPB, AD8331ARQZ, MCP4812-E/MS and MD0100N8-G. By type, the board carries 26 capacitors, 11 resistors, 7 connectors, 5 ICs, 5 inductors and 1 diode.

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…

PICO ADC TEST: common questions

What microcontroller does the PICO ADC TEST use?

The PICO ADC TEST is built around the Pico, from the RP2040/RP2350 family.

How big is the PICO ADC TEST PCB?

The PICO ADC TEST measures 85 × 54 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the PICO ADC TEST?

55 components, from 24 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 PICO ADC TEST design files?

From the kelu124/pic0rick 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 PICO ADC TEST design in my own project?

Yes, under the terms of its TAPR-OHL-1.0 license, which kelu124 chose for the repository.

Can I test firmware for the PICO ADC TEST without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug RP2040/RP2350 firmware against it before you order a PCB.
