ServoShield: common questions

What microcontroller does the ServoShield use?

The ServoShield is built around the ARDUINO_SHIELD, from the AVR/Arduino family.

How big is the ServoShield PCB?

The ServoShield measures 68.6 × 53.3 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the ServoShield?

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

Where can I download the ServoShield design files?

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

Can I use the ServoShield design in my own project?

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

Can I test firmware for the ServoShield 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.
