Digit in board: common questions

What microcontroller does the Digit in board use?

The Digit in board is built around the STM32G070RBTx (LQFP-64), from the STM32 family.

How big is the Digit in board?

The Digit in board measures 91.6 × 64.5 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Digit in board?

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

Where can I download the Digit in board design files?

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

Can I use the Digit in board design in my own project?

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

Can I test firmware for the Digit in board without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug STM32 firmware against it before you order a PCB.
