PicoRF Blk2B: common questions
What microcontroller does the PicoRF Blk2B use?
The PicoRF Blk2B is built around the NRF52833-QDAA-R7, from the Nordic nRF family.
How big is the PicoRF Blk2B PCB?
The PicoRF Blk2B measures 15 × 30 mm, has 4 copper layers and is 1 mm thick.
How many components are on the PicoRF Blk2B?
60 components, from 39 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 PicoRF Blk2B design files?
From the madkoding/slimestuff 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 PicoRF Blk2B design in my own project?
The repository has no license, so all rights stay with madkoding. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the PicoRF Blk2B 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.
