Palm: common questions

What microcontroller does the Palm use?

The Palm is built around the 3406, from the Nordic nRF family.

How big is the Palm PCB?

The Palm measures 29.8 × 70.5 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Palm?

11 components, from 8 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 Palm design files?

From the hutscape/palm repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the Palm design in my own project?

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

Can I test firmware for the Palm without the hardware?

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