Note: if you are looking for an 'out of the box' ready to be used Gateway, please select the Lorank 8 gateway.
The 915 MHz type is available. Please check out the IC980A. The 433 MHz wil follow soon.
The iC880A is able to receive packets of different end devices send with different spreading factors on up to 8 channels in parallel. Due to the fact that the combination of spreading factors and signal bandwidths results in different data rates the use of “Dynamic Data-Rate Adaption” becomes possible. That means that LoRa™ nodes with high distances from the concentrator must use higher spreading factors and therefore have a lower data rate. LoRa™ nodes which are closer to the concentrator can use lower spreading factors and therefore can increase their data rate. This allows to build easy to handle star or multiple star networks without the need of routers or repeaters.
The LoRa™ MAC specification is currently driven by the LoRa Alliance . Currently all available software, firmware and documentation can be found and downloaded from the open source project LoRa-net. It is highly recommended to fully re-use the latest HAL as provided by Semtech on https://github.com/Lora-net
The iC880A is the RF frontend of a LoRa™ gateway. It is able to receive on different frequency channels at the same time and is able to demodulate the LoRa™ signal without knowledge of the used spreading factor of the sending node.

The board has an u.fl-connector (male) at the antenna port. To connect the SMA-antenna accessory, a pigtail (cable) is required. Ideetron can modify the board so it is supplied with a SMA connector. Please contact us for more information about modifications and options.
Powering the iC880A-SPI board is through a 20+3+3-pin row header, powering is through pin 21 & 22. Please refer documentation for details.
