Flow controller: common questions

What microcontroller does the Flow controller use?

The Flow controller is built around the MSP430FR5994IPNR, from the TI MSP430/CC family.

How big is the Flow controller PCB?

The Flow controller measures 76.2 × 44.5 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Flow controller?

59 components, from 35 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 Flow controller design files?

From the NOAA-PMEL/ASVCO2 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 Flow controller design in my own project?

Yes, under the terms of its BSD-3-Clause license, which NOAA-PMEL chose for the repository.

Can I test firmware for the Flow controller 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.
