From the project

RP2040 RTC Module, highly compatible with JLCPCB's basic SMT components.

The Hummingbird RP2040 Clock Module is designed for crafting artisan clocks by pairing it with different clock faces. Its modular design allows this project to be shared across various display technologies.

The KiCad project lives in the MitchellStride/Hummingbird-RP2040-Clock-Module repository on GitHub; these links point at the commit this page was built from.

Clock module v2.0: common questions

What microcontroller does the Clock module v2.0 use?

The Clock module v2.0 is built around the RP2040, from the RP2040/RP2350 family.

How big is the Clock module v2.0?

The Clock module v2.0 measures 161.2 × 119.9 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Clock module v2.0?

107 components, from 65 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 Clock module v2.0 design files?

From the MitchellStride/Hummingbird-RP2040-Clock-Module 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 Clock module v2.0 design in my own project?

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

Can I test firmware for the Clock module v2.0 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.
