RbServo design files

The KiCad project lives in the RasmusB/rbServo repository on GitHub; these links point at the commit this page was built from.

RbServo: common questions

What microcontroller does the RbServo use?

The RbServo is built around the ATMEGA32M1_QFN32, from the AVR/Arduino family.

How big is the RbServo PCB?

The RbServo measures 17.8 × 28.5 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the RbServo?

31 components, from 22 distinct parts. The full bill of materials is listed on this page.

Where can I download the RbServo design files?

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

Can I use the RbServo design in my own project?

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

Can I test firmware for the RbServo 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.
