As discussed in a previous blog post the iC880a is a LoRaWAN concentrator that can be used to create a gateway. The iC880a only provides the LoRaWAN hardware, it does not provide any processing capabilities, for this we use a Raspberry Pi. However, the Raspberry Pi and the iC880a have different pin layouts for their

EMF camp 2018 Air Quality LoRaWAN workshop
At EMF camp 2018 we ran three workshops in order to improve people’s understanding of air quality. The workshop details can be found at https://www.emfcamp.org/line-up/2018/180-air-quality-sensor-devices-build-program-and-test. Here are the details needed to recreate the workshop. The workshop was designed to be suitable for anyone with no prior experience using a Raspberry Pi, however, the setup steps

Mapping LoRaWAN coverage in Southampton
Having setup some LoRaWAN base stations to provide coverage of the Southampton area we wanted to see if there are any black spots without coverage, and therefore where new basestations should be deployed. We are also looking to do more work with positioning of LoRaWAN devices so need transmissions from known locations. Rather than developing

Using the Adafruit Ultimate GPS with the iC880A
In an earlier post our experience of adding a uBlox GPS receiver directly onto the PCB of the iC880A, and commented that whilst it was doable it required a tricky soldering, even with the most challenging component needing to be omitted, so we looked into ways of adding a GPS module without needed surface mount

Adding a GPS Receiver to the iC880A LoRaWAN concentrator
Hardware setup The iC880A is a popular PCB for creating a multichannel LoRaWAN base station. It is supplied with pads for the addition of a u-blox LEA-6T. As well as adding the GPS receiver module several other components have to be added including a power supply, USB connector and associated passives / TVS protection diodes.
