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.

PB04 – Dual AA Intelligent Battery Power Pack xChip (AAT1217, INA199, MAX11647

This xChip is a power module that houses 2 x AA batteries to supply power to other connected xChips. The PB04 makes use of the INA199A2 current sensor and MAX11647 Analog to Digital Converter. These two low-cost precision sensors allows for accurate power measurement usage, battery voltage and current draw.

The PB04 features an AAT1217, which is a highly efficient, synchronous, fixed frequency (1.2 MHz), step-up converter designed for battery-powered applications. The high switching frequency and integrated control circuitry maintains excellent regulation, ripple, and transient response throughout the full load range.

Light load operation and low quiescent current allow the AAT1217 to maintain high efficiency performance for light load conditions. A 1.2A peak inductor current limit, allow for the AAT1217 is capable of delivering 400mA from dual AA cells batteries.
