Alleycat right: common questions
What microcontroller does the Alleycat right use?
The Alleycat right is built around the nRF52840_holyiot_18010, from the Nordic nRF family.
How big is the Alleycat right PCB?
The Alleycat right measures 139.8 × 136.9 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Alleycat right?
116 components, from 32 distinct parts. The full bill of materials is listed on this page.
Where can I download the Alleycat right design files?
From the hextral/alleycat repository on GitHub, which has the KiCad layout; the links under Design files point to each one.
Can I use the Alleycat right design in my own project?
The repository has no license, so all rights stay with hextral. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Alleycat right 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.
