NRF-MCU module: common questions
What microcontroller does the NRF-MCU module use?
The NRF-MCU module is built around the NRF52840-QIAA-R7, from the Nordic nRF family.
How big is the NRF-MCU module?
The NRF-MCU module measures 69.8 × 30.8 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the NRF-MCU module?
76 components, from 45 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 NRF-MCU module design files?
From the AnotherBuildCorner/Hyper_Wheel repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.
Can I use the NRF-MCU module design in my own project?
The repository has no license, so all rights stay with AnotherBuildCorner. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the NRF-MCU 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.
