Cw lite main: common questions
What microcontroller does the Cw lite main use?
The Cw lite main is built around the 8444-11B1-RK-TP, from the Microchip SAM family.
How big is the Cw lite main PCB?
The Cw lite main measures 117 × 60 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the Cw lite main?
324 components, from 86 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 Cw lite main design files?
From the nikitalita/cw-kicad-conversions 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 Cw lite main design in my own project?
The repository has no license, so all rights stay with nikitalita. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Cw lite main 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.
