Introduction

This document provides detailed information on DSPWorks’ India band standalone LoRa module named IdIoT, offering high transmit power at lower power consumption. The IdIoT is a naïve module without any integrated MCU, allowing easy and seamless connections with any host like Arduino, Raspberry Pi etc. to create a LoRaWAN gateway or any powerful node.

Features

  • LoRa and FSK technology supported
  • Can be configured for Class A and Class C LoRa mode operations
  • Compatible with RPi3, Arduino and wide range of MCUs
  • Open source codes available for Raspberry Pi3 and Arduino
  • 30dBm Transmit Power
  • -136 dBm Receiver sensitivity
  • Low Receiver current consumption : <20mA
  • Standby mode current consumption : <100uA
  • Sleep mode current consumption : 2uA
  • Available for India free band, 865MHz to 867 MHz

Description

DSPWorks’ IdIoT uses Semtech’s SX1276 chip for LoRa along with additional PA and LNA to boost power for even longer range. The IdIoT can also be used in FSK mode.

IdIoT is a perfect radio card for LoRa/LoRaWAN Gateways made on powerful boards like Raspberry Pi3 or Olimex A10/A20 etc. This radio card also makes a powerful node when configured with high performance host likes Arduino.

Designed in an optimum 35mm x 50mm size, it ensures all your IoT applications are fulfilled with best performance and cost.

 

Applications

LoRa Gateway

End Node for LoRaWAN

Simple LoRa Radios for peer to peer communications

Physical Dimension

Available Applications

  • R-Pi based LoRa Gateway

An IdIoT mounted on Raspberry Pi with the help of a Pi-Hat can be configured for LoRa or LoRaWAN Gateway. The Open Source code for this kind of LoRaWAN gateway is available on internet. Please visit DSPWorks’ web shop at dspworks.in/shop for product details and availability.

Notes

  • Ensure there is no polarity swap at input voltage
  • Link Budget calculation will depend on mode and configuration
  • IdIoT is only a Radio module, MCU is needed for it to work

Warnings

  • TX Power of SX1276 should never exceed 8dBm. Power higher than this can damage RF front End and/or IdIoT
  • Never power up IdIoT without antenna connected to it. The RF reflection can damage radio transceiver
  • Power supply less than 4.5V can cause performance issues
  • Make sure power supply is able to supply a peak current of 1A to achieve maximum TX Power and maximum range
