xChip Boards

xChips are a rapid electronics development ecosystem to help reduce development time and simplify making custom products as well as aiding learning. Without soldering, wiring, breadboarding, or hardware knowledge you can assemble a circuit in minutes, and concentrate on coding.

xChips are compatible with the platform you want to use and bridges are available for the most popular pltatforms; Raspberry Pi, Minnowboard, Beaglebone, Micro:bit, Pixhawk and 96 boards. Rather than bridging to Ardunio, we offer compatible cores for Arduino Uno, the CC01, and for Arduino Zero, the CC03.

xChips utilise I2C, and due to this bus architecture, unlimited expansion of circuits is possible. Limitations of I2C addresses have been negated by development multiplexers.

Because of its simple connection method, it is easy to build quickly - for prototyping and small product runs

xChips connect to each other using an xBus connector, available from RS 174-4977.

Some xChips need an xPDI connector (RS 174-4974) to connect to programming interfaces, such as the IP02 or IP03.

AI04 – I2C Extender (P82B715DR / P82B715)

This xChip is an interface module, based on the P82B715DR by Texas Instruments, that is a bipolar device intended for I²C bus systems applications and supports bidirectional data transfer via the I²C bus. The P82B715DR buffers both the serial data (SDA) and serial clock (SCL) signals on the I²C bus and allows expansion of the I²C bus, while retaining all the operating modes and features of the I²C system.

3.3 volt from are also transmitted from one AI04 to another AI04, eliminating the need for separate power on the receiving end.
No specific coding is required to use a pair of AI04 as the I²C signal is transmitted transparently between the 2 sides.

A pair of AI04 are interconnected using patch cable (straight) version of the well-known RJ11 telephone style cable and plug points.

Product Features

● Supports bidirectional data transfer of I²C bus signals and 3.3 volt power.


● Long I²C communications
● Industrial communications
● Specific location or facing of sensors of other xChips

Product Specifications

● Dual bidirectional unity-voltage-gain buffer with no external directional control required.
● Drives 10x lower-impedance bus wiring for improvised noise immunity.
● Multi-drop distance of I²C signals using low-cost twisted-pair cables.
● I²C bus operation over 50 meters of twisted-pair wire.
