The Qwiic Iridium 9603 allows you to send and receive short messages. It works anywhere in the world, far beyond the reach of WiFi and GSM networks. Maybe you want to transmit weather information from a weather station on top of a mountain? Or use it to send data from a travelling balloon sat? Perhaps you need to communicate in an emergency, when other networks might not be available?
At the heart of our product is an Iridium 9603 modem. The Qwiic module hosts the 9603 and provides it with an antenna, and its power supply requirements. The modem’s serial interface is translated into I2C commands by the ATtiny841 microcontroller.
Sending and receiving messages to the Iridium network is as easy as sending I2C commands from your RedBoard over a Qwiic connector. The Arduino library walks you through sending messages to the Iridium network using your Qwiic Iridium 9603. An online portal allows you to send messages from the Iridium satellite network to your modem.
