Farlock3-hw: common questions

What microcontroller does the Farlock3-hw use?

The Farlock3-hw is built around the MDBT50Q, from the Nordic nRF family.

How big is the Farlock3-hw PCB?

The Farlock3-hw measures 58 × 22.5 mm, has 2 copper layers and is 1.6256 mm thick.

How many components are on the Farlock3-hw?

43 components, from 26 distinct parts. The full bill of materials is listed on this page.

Where can I download the Farlock3-hw design files?

From the frazieje/farlock3-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 Farlock3-hw design in my own project?

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

Can I test firmware for the Farlock3-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.
