MSBE V3 BGA 6-layer: common questions
What microcontroller does the MSBE V3 BGA 6-layer use?
The MSBE V3 BGA 6-layer is built around the MPR121QR2, from the Nordic nRF family.
How big is the MSBE V3 BGA 6-layer PCB?
The MSBE V3 BGA 6-layer measures 55.9 × 8.7 mm, has 6 copper layers and is 1.6 mm thick.
How many components are on the MSBE V3 BGA 6-layer?
85 components, from 68 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 MSBE V3 BGA 6-layer design files?
From the Monty103/MSBE_v3 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 MSBE V3 BGA 6-layer design in my own project?
The repository has no license, so all rights stay with Monty103. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the MSBE V3 BGA 6-layer 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.
