Bit v5.0.0: common questions

What microcontroller does the Bit v5.0.0 use?

The Bit v5.0.0 is built around the ATmega328P-P, from the AVR/Arduino family.

How big is the Bit v5.0.0 PCB?

The Bit v5.0.0 measures 97 × 75 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Bit v5.0.0?

39 components, from 30 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the Bit v5.0.0 design files?

From the alazifi/baby-incubator-tester repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.

Can I use the Bit v5.0.0 design in my own project?

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

Can I test firmware for the Bit v5.0.0 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.
