Nsumo hardware: common questions
What microcontroller does the Nsumo hardware use?
The Nsumo hardware is built around the MSP430G2553IPW28, from the TI MSP430/CC family.
How big is the Nsumo hardware PCB?
The Nsumo hardware measures 50 × 65 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Nsumo hardware?
73 components, from 55 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 Nsumo hardware design files?
From the artfulbytes/nsumo_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 Nsumo hardware design in my own project?
Yes, under the terms of its MIT license, which artfulbytes chose for the repository.
Can I test firmware for the Nsumo hardware without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug TI MSP430/CC firmware against it before you order a PCB.
