SenseBe rev2: common questions
What microcontroller does the SenseBe rev2 use?
The SenseBe rev2 is built around the TLV8802, from the Nordic nRF family.
How big is the SenseBe rev2 PCB?
The SenseBe rev2 measures 60 × 40 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the SenseBe rev2?
43 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 SenseBe rev2 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 SenseBe rev2 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 SenseBe rev2 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.
