About the I2C Splitter PCB

I2C Splitter is an open source PCB design by Accessible-AAC, published on GitHub. It is a 2-layer board measuring 25.2 × 23.4 mm, with 3 components from 1 distinct parts.

From the project

Augmentative and alternative communications device design files based on inexpensive and open source technologies.

These directories contain design files for an i2c bus splitter, for use with an i2c (green) controller input.

This splitter can be used to connect two i2c (green base) peripherals to the same i2c (green) input port.

(Multiple splitters can be daisy-chained together to accommodate more i2c peripherals, subject to i2c bus limitation with respect to peripheral addressing.)

I2C Splitter: common questions

How big is the I2C Splitter PCB?

The I2C Splitter measures 25.2 × 23.4 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the I2C Splitter?

3 components, from 1 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 I2C Splitter design files?

From the Accessible-AAC/AAC-Devices repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the I2C Splitter design in my own project?

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