LaunchController: common questions
What microcontroller does the LaunchController use?
The LaunchController is built around the ATMEGA2560-16A, from the AVR/Arduino family.
How big is the LaunchController PCB?
The LaunchController measures 150 × 100 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the LaunchController?
153 components, from 76 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 LaunchController design files?
From the tokai-student-rocket-project/Gen6-GSE-Elec 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 LaunchController design in my own project?
Yes, under the terms of its MIT license, which tokai-student-rocket-project chose for the repository.
Can I test firmware for the LaunchController 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.
