Igniter: common questions
What microcontroller does the Igniter use?
The Igniter is built around the Arduino_Mega2560_Shield, from the AVR/Arduino family.
How big is the Igniter PCB?
The Igniter measures 124.9 × 69.6 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Igniter?
54 components, from 26 distinct parts. The full bill of materials is listed on this page.
Where can I download the Igniter design files?
From the AndrewHauck/RDT repository on GitHub, which has the KiCad layout; the links under Design files point to each one.
Can I use the Igniter design in my own project?
The repository has no license, so all rights stay with AndrewHauck. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Igniter without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug AVR/Arduino firmware against it before you order a PCB.
