Snap badge hardware: common questions

What microcontroller does the Snap badge hardware use?

The Snap badge hardware is built around the TPS61070, from the NXP family.

How big is the Snap badge hardware PCB?

The Snap badge hardware measures 63.5 × 127 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Snap badge hardware?

138 components, from 37 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 Snap badge hardware design files?

From the synapse-wireless/snap-badge-hardware repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the Snap badge hardware design in my own project?

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

Can I test firmware for the Snap badge hardware without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug NXP firmware against it before you order a PCB.
