About the Pico hx PCB

Pico hx is an open source RP2040/RP2350 PCB design by dan-rodrigues, published on GitHub. It is a 4-layer board measuring 80.8 × 65.8 mm, with 67 components from 27 distinct parts.

Its main chip is the Pico, from the RP2040/RP2350 family. Other key parts include the ICE40HX1K-TQ144, PSRAM and MIC5504-1.2YM5. By type, the board carries 21 resistors, 20 capacitors, 9 connectors, 9 diodes, 4 ICs and 4 switches.

From the project

PCB combining Raspberry Pi Pico and iCE40 FPGA

This is an FPGA board that combines an iCE40 HX FPGA with the Raspberry Pi Pico. The Pico can program the FPGA over USB using a script included in this repo and then interact with it using GPIO.

Pictured is an included DVI demo. First, the RP2040 was programmed with the USB software which then exposes a USB programmer device to the host. Then, the FPGA configuration containing the DVI test pattern config was uploaded from the host to the RP2040, which then programmed the FPGA, which then displayed the test pattern on screen. This DVI PMOD was used.

Pico hx: common questions

What microcontroller does the Pico hx use?

The Pico hx is built around the Pico, from the RP2040/RP2350 family.

How big is the Pico hx PCB?

The Pico hx measures 80.8 × 65.8 mm, has 4 copper layers and is 1.6002 mm thick.

How many components are on the Pico hx?

67 components, from 27 distinct parts. The full bill of materials is listed on this page.

Where can I download the Pico hx design files?

From the dan-rodrigues/pico-hx repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the Pico hx design in my own project?

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

Can I test firmware for the Pico hx 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.
