Remotely-operated quadcopter hardware, firmware and software
You don't have to, but using a venv for the following steps is a good idea. To create one, run:
Then to activate it, run the following. You'll need to do this each time you open a new shell, but you can put it in your shell's dotfile to automate this.
Open PowerShell as an administrator and install chocolatey using these instructions.
Still using an administrator shell, install dependencies with:

Low power: common questions
What microcontroller does the Low power use?
The Low power is built around the RP2040, from the RP2040/RP2350 family.
How big is the Low power PCB?
The Low power measures 128.5 × 45 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the Low power?
183 components, from 91 distinct parts. The full bill of materials is listed on this page.
Where can I download the Low power design files?
From the ShaneTWilliams/capstone repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the Low power design in my own project?
The repository has no license, so all rights stay with ShaneTWilliams. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Low power 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.
