LCD Receiver Mini Kit
This is a mini kit to build the LCD Receiver. The receiver has been designed primarily as a LoRa GPS tracker receiver, it’s easy to build and with minimal components. You will need to source some components yourself, the kit does not include an Arduino Pro Mini 3.3V, LCD Display, GPS, UHF antenna or battery. A full list of parts supplied in the mini kit is here;£18.00 Price Each

What is different about LoRa ?
Unlike other methods of radio communication, LoRa receivers operate below noise level. Thus they can receive signals that are much weaker and have travelled for much greater distances.
So how good is LoRa ?
LoRa devices can typically receive signals at 10 times the distance of other simple tranceiver modules. In addition LoRa can operate at very low data rates which extends range even further.
Semtech SX1280 2.4ghz LoRa Ranging Tranceivers
The Semtech SX1280 LoRa devices bring long range LoRa technology to the 2.4ghz bands. The devices allow for much higher data throughput than the lower frequency LoRa devices, data transfer speeds are up to 203kbps.
The SX1280 also has a...
LoRa Signal Quality – RSSI or SNR?
It’s helpful to know how good the LoRa signals you are receiving are, or perhaps more importantly how close the are to failure.
The LoRa device measures two things during packet reception, the received signal strength indicator (RSSI) measured...
LoRa – does CAD work at weak signal levels ?
The SX127x data sheet defines CAD as;
When in CAD mode, the device will check a given channel to detect LoRa preamble signal
Principle of Operation
The channel activity detection mode is designed to detect a LoRa preamble on the radio channel...
