LaunchController2.0: common questions
What microcontroller does the LaunchController2.0 use?
The LaunchController2.0 is built around the ATMEGA2560-16A, from the AVR/Arduino family.
How big is the LaunchController2.0 PCB?
The LaunchController2.0 measures 150 × 100 mm, has 2 copper layers and is 1.6062 mm thick.
How many components are on the LaunchController2.0?
180 components, from 77 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 LaunchController2.0 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 LaunchController2.0 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 LaunchController2.0 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.
