Smart coaster-: common questions

What microcontroller does the Smart coaster- use?

The Smart coaster- is built around the RaspberryPi_Pico, from the RP2040/RP2350 family.

How big is the Smart coaster- PCB?

The Smart coaster- measures 69 × 77 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Smart coaster-?

19 components, from 13 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 Smart coaster- design files?

From the EveyKay/Smart-coaster- 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 Smart coaster- design in my own project?

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

Can I test firmware for the Smart coaster- without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug RP2040/RP2350 firmware against it before you order a PCB.
