BL54L15μ Hygrometer: common questions

What microcontroller does the BL54L15μ Hygrometer use?

The BL54L15μ Hygrometer is built around the 453-00223R, from the Nordic nRF family.

How big is the BL54L15μ Hygrometer PCB?

The BL54L15μ Hygrometer measures 48 × 48 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the BL54L15μ Hygrometer?

19 components, from 14 distinct parts. The full bill of materials is listed on this page.

Where can I download the BL54L15μ Hygrometer design files?

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

Can I use the BL54L15μ Hygrometer design in my own project?

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

Can I test firmware for the BL54L15μ Hygrometer 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.
