Sensor board: common questions
What microcontroller does the Sensor board use?
The Sensor board is built around the RP2040, from the RP2040/RP2350 family.
How big is the Sensor board?
The Sensor board measures 40 × 70 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the Sensor board?
205 components, from 61 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 Sensor board design files?
From the TrendBit/SMBR-hardware 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 Sensor board design in my own project?
Yes, under the terms of its GPL-3.0 license, which TrendBit chose for the repository.
Can I test firmware for the Sensor board 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.
