Pycom LoRa Sigfox Antenna Kit

Jargon buster

Plain-language definitions for the technical terms used above.

IoT

Short for Internet of Things, meaning physical devices that connect to networks or the internet to send data or be controlled remotely. It matters if you want projects such as connected sensors, remote controls or classroom data-logging activities.

LoRa

LoRa is a long-range, low-power wireless radio technology often used for telemetry, remote sensors and other links that send small amounts of data over long distances. It is distinct from Bluetooth and WiFi, so sharing a connector or pinout with LoRa hardware does not mean a device actually uses LoRa.

RF

RF means radio frequency, referring to signals used for wireless communication and other high-frequency electronics. A low-noise, stable power supply is important for RF circuits because power noise can affect signal quality and measurements.

SMA

SMA is a small threaded coaxial (RF) connector widely used to attach antennas and other radio-frequency cables. A device with SMA antenna ports needs antennas or pigtails with matching SMA connectors, or a suitable adapter, to connect to them.

u.FL

u.FL is a tiny snap-on antenna connector often used on compact wireless boards. A board with u.FL usually needs an external antenna, which matters if the product will be inside an enclosure or needs better antenna placement.
