Ssense lte: common questions
What microcontroller does the Ssense lte use?
The Ssense lte is built around the nRF9160-SICA-B1A-R7, from the Nordic nRF family.
How big is the Ssense lte PCB?
The Ssense lte measures 113 × 25.1 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the Ssense lte?
105 components, from 53 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 Ssense lte design files?
From the fredriknk/ssense-lte 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 Ssense lte design in my own project?
Yes, under the terms of its MIT license, which fredriknk chose for the repository.
Can I test firmware for the Ssense lte 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.
