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.

CR03 – LoRa with Uno Core (868 MHz) (RFM96W/RFM96, ATmega328P/ATmega328)

This xChip is a core radio module, based on the ATmega328P, which is a single-chip microcontroller. This xChip also features an on-board RFM96W LoRa module. The ATmega328P is the same architecture as Arduino Pro / Pro Mini, allowing users to program in the Arduino IDE and other IDEs supporting the Arduino Pro, such as PlatformIO and Mbed.

The ATmega328P is Atmel’s 8-bit AVR RISC-based microcontroller that combines 32 kB flash memory, 1 kB EEPROM and 2 kB internal SRAM, running at 16 MHz. This xChip can communicate using I2C, and UART.

This xChip also features an on-board RFM96W LoRa™ module that provides ultra-long range spread spectrum communication and high interference immunity whilst minimizing current consumption.

The LoRa™ module on this xChip is the 915 MHz version, which forms part of the license-free ISM band for ITU region 2 (North and South America).
