HolidayExpress: common questions

What microcontroller does the HolidayExpress use?

The HolidayExpress is built around the ESP32-PICO-MINI-02, from the RP2040/RP2350 family.

How big is the HolidayExpress PCB?

The HolidayExpress measures 50 × 50 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the HolidayExpress?

17 components, from 14 distinct parts. The full bill of materials is listed on this page.

Where can I download the HolidayExpress design files?

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

Can I use the HolidayExpress design in my own project?

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

Can I test firmware for the HolidayExpress 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.
