SAO stick sideways: common questions
What microcontroller does the SAO stick sideways use?
The SAO stick sideways is built around the Pico, from the RP2040/RP2350 family.
How big is the SAO stick sideways PCB?
The SAO stick sideways measures 153.4 × 25 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the SAO stick sideways?
8 components, from 4 distinct parts. The full bill of materials is listed on this page.
Where can I download the SAO stick sideways design files?
From the davedarko/Simple-Add-ons-SAO repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the SAO stick sideways design in my own project?
The repository has no license, so all rights stay with davedarko. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the SAO stick sideways 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.
