Tijuana: common questions

What microcontroller does the Tijuana use?

The Tijuana is built around the rp2040-zero, from the RP2040/RP2350 family.

How big is the Tijuana PCB?

The Tijuana measures 304.4 × 98.8 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Tijuana?

170 components, from 8 distinct parts. The full bill of materials is listed on this page.

Where can I download the Tijuana design files?

From the digitarhythm/TIJUANA repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Tijuana design in my own project?

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

Can I test firmware for the Tijuana 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.
