About the OWL - Rotor v2 PCB

OWL - Rotor v2 is an open source RP2040/RP2350 PCB design by sedlak477, published on GitHub under the CERN-OHL-P-2.0 license. It is a 4-layer board measuring 60 × 60 mm, with 104 components from 54 distinct parts.

Its main chip is the 781715006, from the RP2040/RP2350 family. Other key parts include the USB2422-I/MJ, AP2112K-3.3TRG1, LM66200DRLR, DRV8311HRRWR and RP2354B. By type, the board carries 43 capacitors, 33 resistors, 7 ICs, 7 connectors, 7 diodes and 3 switches.

It belongs with the robotics & motion and iot & wireless designs in this gallery.

From the project

Hardware design files and build instructions for the OWL platform

ENIG surface finish is recommended. Minimum track width and clearance are 0.15 mm, minimum drill is 0.25 mm (controller) or 0.3 mm (stator, sensor).

The easiest way to get the files is the latest release: owl--jlcpcb.zip has the JLCPCB files and owl--generic.zip the generic files and schematics, each with one folder per board.

Order each board (controller, stator, sensor-ma600a) separately. Download and unzip owl--jlcpcb.zip, then for each board:

OWL - Rotor v2: common questions

What microcontroller does the OWL - Rotor v2 use?

The OWL - Rotor v2 is built around the 781715006, from the RP2040/RP2350 family.

How big is the OWL - Rotor v2 PCB?

The OWL - Rotor v2 measures 60 × 60 mm, has 4 copper layers and is 1.579 mm thick.

How many components are on the OWL - Rotor v2?

104 components, from 54 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 OWL - Rotor v2 design files?

From the sedlak477/owl-hardware 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 OWL - Rotor v2 design in my own project?

Yes, under the terms of its CERN-OHL-P-2.0 license, which sedlak477 chose for the repository.

Can I test firmware for the OWL - Rotor v2 without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug RP2040/RP2350 firmware against it before you order a PCB.
