About the Phial hw PCB

Phial hw is an open source Nordic nRF PCB design by golioth, published on GitHub under the CERN-OHL-P-2.0 license. It is a 6-layer board measuring 22.1 × 22.1 mm, with 86 components from 40 distinct parts.

Its main chip is the NRF54L15-QFAA-R, from the Nordic nRF family. Other key parts include the NPM2100-CAAA-R, LIS2DH, WLA.04, ATECC608B-MAHDA and LF21115TMR. By type, the board carries 26 resistors, 23 capacitors, 13 diodes, 8 ICs, 6 inductors and 4 LEDs.

It belongs with the iot & wireless and sensors designs in this gallery.

From the project

Bluetooth sensor, 22 mm

A small (~22 mm diameter, round) battery-powered Bluetooth LE sensor board from Golioth. Rev B.

[UNKNOWN] The schematic also references an nRF52840-CKAA-F-R (WLCSP) symbol and a BME280. It is unclear whether these are an alternate/deprecated variant, DNP on Rev B, or planned future population. Needs a pass against the Rev B BOM.

- The only boards ever built were assembled without the nPM2100. A zero-ohm resistor selects the function and bypasses that section of the circuit, so the built variant runs without the Nordic PMIC. - Consequence: the nPM2100 power path (battery management via…

Phial hw: common questions

What microcontroller does the Phial hw use?

The Phial hw is built around the NRF54L15-QFAA-R, from the Nordic nRF family.

How big is the Phial hw PCB?

The Phial hw measures 22.1 × 22.1 mm, has 6 copper layers and is 0.8464 mm thick.

How many components are on the Phial hw?

86 components, from 40 distinct parts. The full bill of materials is listed on this page.

Where can I download the Phial hw design files?

From the golioth/phial-hw repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Phial hw design in my own project?

Yes, under the terms of its CERN-OHL-P-2.0 license, which golioth chose for the repository.

Can I test firmware for the Phial hw 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.
