SenseEle SMA rev1: common questions

What microcontroller does the SenseEle SMA rev1 use?

The SenseEle SMA rev1 is built around the MDBT42Q, from the Nordic nRF family.

How big is the SenseEle SMA rev1 PCB?

The SenseEle SMA rev1 measures 49 × 45 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the SenseEle SMA rev1?

51 components, from 37 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 SenseEle SMA rev1 design files?

From the Appiko/sense_snap_hw repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the SenseEle SMA rev1 design in my own project?

Yes, under the terms of its CERN-OHL-1.2 license, which Appiko chose for the repository.

Can I test firmware for the SenseEle SMA rev1 without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug Nordic nRF firmware against it before you order a PCB.
