Haptic bracelet: common questions

What microcontroller does the Haptic bracelet use?

The Haptic bracelet is built around the RaspberryPi_Pico_W, from the RP2040/RP2350 family.

How big is the Haptic bracelet PCB?

The Haptic bracelet measures 21.3 × 52.5 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Haptic bracelet?

47 components, from 28 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 Haptic bracelet design files?

From the plerros/Haptic-Bracelet 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 Haptic bracelet design in my own project?

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

Can I test firmware for the Haptic bracelet 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.
