Octoray VFD: common questions
What microcontroller does the Octoray VFD use?
The Octoray VFD is built around the MSP430G2553_PW20, from the TI MSP430/CC family.
How big is the Octoray VFD PCB?
The Octoray VFD measures 160 × 112.4 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Octoray VFD?
121 components, from 78 distinct parts. The full bill of materials is listed on this page.
Where can I download the Octoray VFD design files?
From the slomkowski/octoglow repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the Octoray VFD design in my own project?
Yes, under the terms of its MIT license, which slomkowski chose for the repository.
Can I test firmware for the Octoray VFD 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.
