Liquid-Engine-Controller: common questions
What microcontroller does the Liquid-Engine-Controller use?
The Liquid-Engine-Controller is built around the STM32H750VBTx, from the STM32 family.
How big is the Liquid-Engine-Controller PCB?
The Liquid-Engine-Controller measures 116.8 × 56.7 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the Liquid-Engine-Controller?
114 components, from 58 distinct parts. The full bill of materials is listed on this page.
Where can I download the Liquid-Engine-Controller design files?
From the SunDevilRocketry/Liquid-Engine-Controller repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the Liquid-Engine-Controller design in my own project?
The repository has no license, so all rights stay with SunDevilRocketry. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Liquid-Engine-Controller without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug STM32 firmware against it before you order a PCB.
