BLE Gauge: common questions

What microcontroller does the BLE Gauge use?

The BLE Gauge is built around the nRF54L15-QFXX, from the Nordic nRF family.

How big is the BLE Gauge PCB?

The BLE Gauge measures 65 × 65 mm, has 4 copper layers and is 1.6062 mm thick.

How many components are on the BLE Gauge?

55 components, from 41 distinct parts. The full bill of materials is listed on this page.

Where can I download the BLE Gauge design files?

From the N4TH4NB/BLE_Gauge repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the BLE Gauge design in my own project?

The repository has no license, so all rights stay with N4TH4NB. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the BLE Gauge 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.
