Okgo2mini: common questions

What microcontroller does the Okgo2mini use?

The Okgo2mini is built around the STM32F051K6T7, from the STM32 family.

How big is the Okgo2mini PCB?

The Okgo2mini measures 67.4 × 39.8 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Okgo2mini?

43 components, from 26 distinct parts. The full bill of materials is listed on this page.

Where can I download the Okgo2mini design files?

From the cuspaceflight/OkGo repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the Okgo2mini design in my own project?

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

Can I test firmware for the Okgo2mini 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.
