Updog: common questions

What microcontroller does the Updog use?

The Updog is built around the MDBT40-256RV3, from the Nordic nRF family.

How big is the Updog PCB?

The Updog measures 22.9 × 62.2 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Updog?

46 components, from 25 distinct parts. The full bill of materials is listed on this page.

Where can I download the Updog design files?

From the stevenpetryk/updog repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the Updog design in my own project?

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

Can I test firmware for the Updog 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.
