DOOOPE: common questions

What microcontroller does the DOOOPE use?

The DOOOPE is built around the xiao-ble, from the Nordic nRF family.

How big is the DOOOPE PCB?

The DOOOPE measures 129.9 × 98.7 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the DOOOPE?

37 components, from 6 distinct parts. The full bill of materials is listed on this page.

Where can I download the DOOOPE design files?

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

Can I use the DOOOPE design in my own project?

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

Can I test firmware for the DOOOPE 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.
