UTILITY TIME MODULE: common questions

What microcontroller does the UTILITY TIME MODULE use?

The UTILITY TIME MODULE is built around the ATtiny45, from the AVR/Arduino family.

How big is the UTILITY TIME MODULE?

The UTILITY TIME MODULE measures 13 × 14 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the UTILITY TIME MODULE?

53 components, from 8 distinct parts. The full bill of materials is listed on this page.

Where can I download the UTILITY TIME MODULE design files?

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

Can I use the UTILITY TIME MODULE design in my own project?

Yes, under the terms of its GPL-3.0 license, which CodapopKSP chose for the repository.

Can I test firmware for the UTILITY TIME MODULE 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.
