Payload gimbal: common questions

What microcontroller does the Payload gimbal use?

The Payload gimbal is built around the ATMEGA32U4-AU, from the AVR/Arduino family.

How big is the Payload gimbal PCB?

The Payload gimbal measures 94 × 94 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Payload gimbal?

59 components, from 33 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 Payload gimbal design files?

From the icl-rocketry/payload_gimbal repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the Payload gimbal design in my own project?

Yes, under the terms of its MIT license, which icl-rocketry chose for the repository.

Can I test firmware for the Payload gimbal 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.
