Servo tester: common questions

What microcontroller does the Servo tester use?

The Servo tester is built around the ATTINY13A-SS, from the AVR/Arduino family.

How big is the Servo tester PCB?

The Servo tester measures 39.6 × 23.9 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Servo tester?

10 components, from 8 distinct parts. The full bill of materials is listed on this page.

Where can I download the Servo tester design files?

From the ironiron/servo-tester repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the Servo tester design in my own project?

Yes, under the terms of its Unlicense license, which ironiron chose for the repository.

Can I test firmware for the Servo tester 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.
