Ble sensor: common questions

What microcontroller does the Ble sensor use?

The Ble sensor is built around the NRF52832-QFAA-R, from the Nordic nRF family.

How big is the Ble sensor PCB?

The Ble sensor measures 50 × 30 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Ble sensor?

22 components, from 12 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 Ble sensor design files?

From the MrMarble/ble-sensor 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 Ble sensor design in my own project?

The repository has no license, so all rights stay with MrMarble. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Ble sensor 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.
