XinaBox xCHIP LoRa Radio Module RL02

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.

RL02 – LoRa Radio xChip (868 MHz) (RFM95W/RFM95, SC18IS602B)

This xChip is a LoRa radio module that features an SC18IS602B SPI/I2C converter for handling radio operations. The on-board RFM96W LoRa™ module provides ultra-long range spread spectrum communication and high interference immunity whilst minimizing current consumption.

This is the 868 MHz LoRa radio version. We also sell a 433.92 MHz (RS 174-3728) LoRa and 915 MHz (RS 174-3730) LoRa version of the same radio xChip.
