RC-MultiSwitcher: common questions

What microcontroller does the RC-MultiSwitcher use?

The RC-MultiSwitcher is built around the Teensy3.1_Minimal, from the NXP family.

How big is the RC-MultiSwitcher PCB?

The RC-MultiSwitcher measures 33 × 45.1 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the RC-MultiSwitcher?

30 components, from 13 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 RC-MultiSwitcher design files?

From the juepi/RC-MultiSwitcher 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 RC-MultiSwitcher design in my own project?

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

Can I test firmware for the RC-MultiSwitcher 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.
