Nrf54 promicro: common questions

What microcontroller does the Nrf54 promicro use?

The Nrf54 promicro is built around the NRF54L15-QFAA-R, from the Nordic nRF family.

How big is the Nrf54 promicro PCB?

The Nrf54 promicro measures 18 × 35 mm, has 4 copper layers and is 1.1382 mm thick.

How many components are on the Nrf54 promicro?

54 components, from 36 distinct parts. The full bill of materials is listed on this page.

Where can I download the Nrf54 promicro design files?

From the brendose/nrf54_promicro repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Nrf54 promicro design in my own project?

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

Can I test firmware for the Nrf54 promicro 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.
