UniversalNode: common questions
What microcontroller does the UniversalNode use?
The UniversalNode is built around the Teensy3.6, from the NXP family.
How big is the UniversalNode PCB?
The UniversalNode measures 121.5 × 127.9 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the UniversalNode?
76 components, from 32 distinct parts. The full bill of materials is listed on this page.
Where can I download the UniversalNode design files?
From the DPIclimate/ag-node repository on GitHub, which has the KiCad layout; the links under Design files point to each one.
Can I use the UniversalNode design in my own project?
Yes, under the terms of its MIT license, which DPIclimate chose for the repository.
Can I test firmware for the UniversalNode 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.
