About the Driverino PCB

Driverino is an open source AVR/Arduino PCB design by weirdgyn, published on GitHub under the GPL-3.0 license. It is a 2-layer board measuring 26 × 41 mm, with 73 components from 39 distinct parts.

Its main chip is the ATmega32U4, from the AVR/Arduino family. Other key parts include the ADM3101E and MCT8316ZR. By type, the board carries 26 capacitors, 22 resistors, 7 connectors, 7 diodes, 3 ICs and 2 fuses.

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

From the project

BLDC motor driver based on Arduino Micro Pro and TI MCT8316ZR

Driverino is a pretty simple, low power, driver for BLDC sensored motors. The project target was to create a very small unit capable of driving a motor rated about 50-100W. The board is fitted with ATmega32U4 micro the same of Arduino Micro Pro commercial boards, once the correct bootloader has been burned-in the board should act as an Arduino board (at least for programming/debugging task) and also spin a motor. The project includes: 1. Fully designed 2 layers PCB board (KiCAD); 2. Driverino firmware sources; 3. MCT8316Z library sources.

Driverino: common questions

What microcontroller does the Driverino use?

The Driverino is built around the ATmega32U4, from the AVR/Arduino family.

How big is the Driverino PCB?

The Driverino measures 26 × 41 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Driverino?

73 components, from 39 distinct parts. The full bill of materials is listed on this page.

Where can I download the Driverino design files?

From the weirdgyn/Driverino repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Driverino design in my own project?

Yes, under the terms of its GPL-3.0 license, which weirdgyn chose for the repository.

Can I test firmware for the Driverino 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.
