Elrocket: common questions

What microcontroller does the Elrocket use?

The Elrocket is built around the ATSAMD21G18A-A, from the STM32 family.

How big is the Elrocket PCB?

The Elrocket measures 36 × 64 mm, has 4 copper layers and is 1.600198 mm thick.

How many components are on the Elrocket?

80 components, from 49 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 Elrocket design files?

From the broskicodes/elrocket 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 Elrocket design in my own project?

The repository has no license, so all rights stay with broskicodes. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Elrocket 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.
