Wand: common questions

What microcontroller does the Wand use?

The Wand is built around the ESP32-PICO-D4, from the RP2040/RP2350 family.

How big is the Wand PCB?

The Wand measures 17.5 × 32 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Wand?

52 components, from 33 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 Wand design files?

From the adeboni/math-camp-synth 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 Wand design in my own project?

Yes, under the terms of its GPL-3.0 license, which adeboni chose for the repository.

Can I test firmware for the Wand 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.
