About the Orion - Control Board

Orion - Control Board is an open source STM32 PCB design by AshishA26, published on GitHub. It is a 2-layer board measuring 70 × 82.4 mm, with 69 components from 34 distinct parts.

Its main chip is the C2286, from the STM32 family. Other key parts include the BNO055, INA3221, DFR0753 5V BUCK and PCA9685_PWM_SERVO_DRIVER_IC. By type, the board carries 33 resistors, 10 connectors, 9 capacitors, 6 ICs, 5 jumpers and 4 diodes.

It belongs with the robotics & motion, power & battery and sensors designs in this gallery.

From the project

🐕 Orion is a ROS2-driven, 12-DOF quadruped robot dog that I designed, built, and programmed from scratch.

Orion - Control Board: common questions

What microcontroller does the Orion - Control Board use?

The Orion - Control Board is built around the C2286, from the STM32 family.

How big is the Orion - Control Board?

The Orion - Control Board measures 70 × 82.4 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Orion - Control Board?

69 components, from 34 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 Orion - Control Board design files?

From the AshishA26/Orion-Quadruped 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 Orion - Control Board design in my own project?

The repository has no license, so all rights stay with AshishA26. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Orion - Control Board 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.
