SensebenderGW: common questions

What microcontroller does the SensebenderGW use?

The SensebenderGW is built around the ATSAMD21J, from the Microchip SAM family.

How big is the SensebenderGW PCB?

The SensebenderGW measures 50 × 50 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the SensebenderGW?

70 components, from 46 distinct parts. The full bill of materials is listed on this page.

Where can I download the SensebenderGW design files?

From the mysensors/SensebenderGW repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the SensebenderGW design in my own project?

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

Can I test firmware for the SensebenderGW 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.
