Philly Node: common questions

What microcontroller does the Philly Node use?

The Philly Node is built around the MDBT50Q-U1MV2, from the Nordic nRF family.

How big is the Philly Node PCB?

The Philly Node measures 22 × 39 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Philly Node?

68 components, from 35 distinct parts. The full bill of materials is listed on this page.

Where can I download the Philly Node design files?

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

Can I use the Philly Node design in my own project?

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

Can I test firmware for the Philly Node 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.
