Magnetometer node mainboard: common questions
What microcontroller does the Magnetometer node mainboard use?
The Magnetometer node mainboard is built around the TPS25210LRPWR, from the ESP32 family.
How big is the Magnetometer node mainboard PCB?
The Magnetometer node mainboard measures 193 × 110 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Magnetometer node mainboard?
297 components, from 165 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 Magnetometer node mainboard design files?
From the Benjamin-girard-1/magnetometer-node-old 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 Magnetometer node mainboard design in my own project?
The repository has no license, so all rights stay with Benjamin-girard-1. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Magnetometer node mainboard without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug ESP32 firmware against it before you order a PCB.
