Low-Power Wide-Area Network (LPWAN) or Low-Power Network (LPN) is a type of wireless telecommunication network designed to allow long range communications at a low bit rate among things (connected objects), such as sensors operated on a battery.
Being a communication technology born to satisfy the distributed sensors and IoT devices needs in terms of data streams and internet connectivity, Raspberry Pi couldn’t miss its own LoRa board!
LoraBerry V 1.0 is an extension board for Raspberry Pi. It is an Open Hardware Design. It has two functionalities: a RFM module and an on board Real Time clock powered by a 12 mm battery.
The RF Module is based on SX127x a SPI controlled single chip wireless ISM transceivers. The SX127x transceivers feature the LoRa long range modem that provides ultra-long range spread spectrum communication and high interference immunity whilst minimising current consumption.
The SX127x features:
The real time clock is based on DS3231 with internal oscillator I2C controller. It is full compatible with linux too. The spiral antenna is present, but not welded to reduce the dimensions and cost of shipping. It is possible to connnect an external antenna on X1 RF connector in order to increase the radio coverage.
