Signal Processing Fun (in the sun)
Instead of simulations we can collect real world data by moving several rovers around autonomously in a field. Some rovers will transmit and others will listen and collect data.
- Pre-field acceptance checklist — mandatory release-level, per-Rover, real-radio Zarr, fake-drone, SITL, and restrained physical gates. - Full Rover operational runbook — provisioning, operation, safety, troubleshooting, and recovery details. - Direct-USB gain/RSSI firmware runbook — experimental RAM-boot firmware build, smoke, capture, validation, and rollback. - loaddirectusbfirmware.sh` — downloads the published…

Power board v1: common questions
What microcontroller does the Power board v1 use?
The Power board v1 is built around the ATTINY1616-SN, from the AVR/Arduino family.
How big is the Power board v1?
The Power board v1 measures 100 × 65 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the Power board v1?
133 components, from 97 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 Power board v1 design files?
From the misko/spf 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 Power board v1 design in my own project?
The repository has no license, so all rights stay with misko. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Power board v1 without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug AVR/Arduino firmware against it before you order a PCB.
