About the Sangaboard PCB

Sangaboard is an open source AVR/Arduino PCB design by kitspace-test-repos, published on GitHub under the Custom license license. It is a 2-layer board measuring 65 × 56.5 mm, with 85 components from 48 distinct parts.

Its main chip is the ATMEGA32U4-AU, from the AVR/Arduino family. Other key parts include the MCP1700T-3302E/TT, ULN2003ADR and CAT24C32WI-GT3. By type, the board carries 22 resistors, 15 connectors, 15 capacitors, 8 transistors, 5 ICs and 5 fuses.

It belongs with the robotics & motion designs in this gallery, and the repository also holds 1 earlier revision of it.

From the project

The Sangaboard is a motor controller for unipolar stepper motors such as the cheap 28BYJ-48 motors. The custom board (v0.3) can be programmed as an Arduino Leonardo in the Arduino IDE. Versions 0.1 and 0.2 were based on an Arduino Nano and a couple of Darlington pair ICs. It owes

The Sangaboard is a motor controller for unipolar stepper motors such as the cheap 28BYJ-48 motors. The custom board (v0.3) can be programmed as an Arduino Leonardo in the Arduino IDE. Versions 0.1 and 0.2 were based on an Arduino Nano and a couple of Darlington pair ICs. It owes quite a bit to Fergus Riche's motor board, the hardware developed by OpenScope and the Arduino-based motor controller used by a number of summer students working with Richard Bowman in Cambridge, particularly James Sharkey. It is currently the motor board used by the OpenFlexure Microscope. It was formerly known as…

Sangaboard: common questions

What microcontroller does the Sangaboard use?

The Sangaboard is built around the ATMEGA32U4-AU, from the AVR/Arduino family.

How big is the Sangaboard PCB?

The Sangaboard measures 65 × 56.5 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Sangaboard?

85 components, from 48 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 Sangaboard design files?

From the kitspace-test-repos/Sangaboard repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the Sangaboard design in my own project?

It is published under Custom license, which limits how it may be reused; read the license before building on it.

Can I test firmware for the Sangaboard 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.
