Grove sensor: common questions
What microcontroller does the Grove sensor use?
The Grove sensor is built around the Teensy_3.1, from the NXP family.
How big is the Grove sensor PCB?
The Grove sensor measures 50.8 × 50.8 mm and is 1.6 mm thick.
How many components are on the Grove sensor?
43 components, from 25 distinct parts. The full bill of materials is listed on this page.
Where can I download the Grove sensor design files?
From the samuelclay/grove repository on GitHub, which has the KiCad layout; the links under Design files point to each one.
Can I use the Grove sensor design in my own project?
The repository has no license, so all rights stay with samuelclay. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Grove sensor without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug NXP firmware against it before you order a PCB.
