LO Necklet: common questions
What microcontroller does the LO Necklet use?
The LO Necklet is built around the SAMD20G18A-A, from the Microchip SAM family.
How big is the LO Necklet PCB?
The LO Necklet measures 82.6 × 85.1 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the LO Necklet?
24 components, from 8 distinct parts. The full bill of materials is listed on this page.
Where can I download the LO Necklet design files?
From the gatechipdl/GameOfLight repository on GitHub, which has the KiCad layout; the links under Design files point to each one.
Can I use the LO Necklet design in my own project?
Yes, under the terms of its MIT license, which gatechipdl chose for the repository.
Can I test firmware for the LO Necklet without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug Microchip SAM firmware against it before you order a PCB.
