About the GPSDO DIP PCB

GPSDO DIP is an open source RP2040/RP2350 PCB design by pwengel, published on GitHub. It is a 2-layer board measuring 126.1 × 87.1 mm, with 86 components from 38 distinct parts.

Its main chip is the Pico, from the RP2040/RP2350 family. Other key parts include the 74HC14, U1, DAC8571IDGK, PIC12F675-xP and LM7805_TO220. By type, the board carries 37 resistors, 23 capacitors, 9 ICs, 7 inductors, 6 relays and 2 diodes.

GPSDO DIP: common questions

What microcontroller does the GPSDO DIP use?

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

How big is the GPSDO DIP PCB?

The GPSDO DIP measures 126.1 × 87.1 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the GPSDO DIP?

86 components, from 38 distinct parts. The full bill of materials is listed on this page.

Where can I download the GPSDO DIP design files?

From the pwengel/DIY-GPSDO repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the GPSDO DIP design in my own project?

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

Can I test firmware for the GPSDO DIP 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.
