About the TixClock PCB

TixClock is an open source RP2040/RP2350 PCB design by vinnesttree, published on GitHub under the MIT license. It is a 2-layer board measuring 38.1 × 133.4 mm, with 85 components from 35 distinct parts.

Its main chip is the RP2040, from the RP2040/RP2350 family. Other key parts include the AMS1117-3.3, W25Q32JVSS, SN74LV1T34DBV, DW01A and 8205A. By type, the board carries 31 diodes, 23 resistors, 11 capacitors, 9 ICs, 4 switches and 2 connectors.

It belongs with the power & battery designs in this gallery.

From the project

The Tix Clock was originally sold in 2006 by ThinkGeek. Unfortunately, these are no longer sold. This project hopes to try to recreate this iconic clock in a miniature format.

TixClock: common questions

What microcontroller does the TixClock use?

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

How big is the TixClock PCB?

The TixClock measures 38.1 × 133.4 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the TixClock?

85 components, from 35 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 TixClock design files?

From the vinnesttree/TixClock 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 TixClock design in my own project?

Yes, under the terms of its MIT license, which vinnesttree chose for the repository.

Can I test firmware for the TixClock 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.
