Sense debug: common questions

What microcontroller does the Sense debug use?

The Sense debug is built around the ATtiny1626-MFR, from the AVR/Arduino family.

How big is the Sense debug PCB?

The Sense debug measures 65 × 40 mm, has 4 copper layers and is 0.786 mm thick.

How many components are on the Sense debug?

44 components, from 29 distinct parts. The full bill of materials is listed on this page.

Where can I download the Sense debug design files?

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

Can I use the Sense debug design in my own project?

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

Can I test firmware for the Sense debug without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug AVR/Arduino firmware against it before you order a PCB.
