About the Revo servo PCB

Revo servo is an open source AVR/Arduino PCB design by ratmuds, published on GitHub under the MIT license. It is a 4-layer board measuring 41 × 44 mm, with 49 components from 28 distinct parts.

Its main chip is the ATTINY3216-S, from the AVR/Arduino family. Other key parts include the THVD1420D, INA219AXD and HT7333. By type, the board carries 12 resistors, 10 test points, 7 capacitors, 5 connectors, 4 ICs and 4 diodes.

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

Revo servo: common questions

What microcontroller does the Revo servo use?

The Revo servo is built around the ATTINY3216-S, from the AVR/Arduino family.

How big is the Revo servo PCB?

The Revo servo measures 41 × 44 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Revo servo?

49 components, from 28 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 Revo servo design files?

From the ratmuds/revo 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 Revo servo design in my own project?

Yes, under the terms of its MIT license, which ratmuds chose for the repository.

Can I test firmware for the Revo servo 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.
