M2-smart iot module: common questions
What microcontroller does the M2-smart iot module use?
The M2-smart iot module is built around the NRF52840-QIAA-R, from the Nordic nRF family.
How big is the M2-smart iot module?
The M2-smart iot module measures 80.2 × 22.2 mm, has 4 copper layers and is 0.746 mm thick.
How many components are on the M2-smart iot module?
210 components, from 77 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 M2-smart iot module design files?
From the antmicro/m2-smart-iot-module 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 M2-smart iot module design in my own project?
Yes, under the terms of its Apache-2.0 license, which antmicro chose for the repository.
Can I test firmware for the M2-smart iot module 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.
