Smart-Arrow: common questions

What microcontroller does the Smart-Arrow use?

The Smart-Arrow is built around the NRF52840, from the Nordic nRF family.

How big is the Smart-Arrow PCB?

The Smart-Arrow measures 50 × 13 mm, has 4 copper layers and is 1.600198 mm thick.

How many components are on the Smart-Arrow?

50 components, from 29 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-Arrow design files?

From the artandtechspace/Smart-Arrow 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-Arrow design in my own project?

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

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

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