Scalenode cm4-baseboard: common questions
What microcontroller does the Scalenode cm4-baseboard use?
The Scalenode cm4-baseboard is built around the BSS138-7-F, from the Raspberry Pi family.
How big is the Scalenode cm4-baseboard PCB?
The Scalenode cm4-baseboard measures 128.5 × 40 mm, has 4 copper layers and is 1.586 mm thick.
How many components are on the Scalenode cm4-baseboard?
125 components, from 58 distinct parts. The full bill of materials is listed on this page.
Where can I download the Scalenode cm4-baseboard design files?
From the antmicro/scalenode-cm4-baseboard repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the Scalenode cm4-baseboard design in my own project?
Yes, under the terms of its Apache-2.0 license, which antmicro chose for the repository.
Can I test firmware for the Scalenode cm4-baseboard without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug Raspberry Pi firmware against it before you order a PCB.
