Cyro plunger transmissive photogate: common questions

What microcontroller does the Cyro plunger transmissive photogate use?

The Cyro plunger transmissive photogate is built around the ATTINY1614, from the AVR/Arduino family.

How big is the Cyro plunger transmissive photogate PCB?

The Cyro plunger transmissive photogate measures 122 × 70 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Cyro plunger transmissive photogate?

50 components, from 25 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 Cyro plunger transmissive photogate design files?

From the Llamero/Cryo_Plunger_LED_Array 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 Cyro plunger transmissive photogate design in my own project?

Yes, under the terms of its Apache-2.0 license, which Llamero chose for the repository.

Can I test firmware for the Cyro plunger transmissive photogate 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.
