This simple spring antenna matches great with any of our 433MHz RFM and LoRa breakouts, bonnets and Feathers. They're made of copper-clad wire so you can solder them easily.
They are compact, only ~38mm / 1.5" long, and have 2.5dBi of gain and 50Ω impedance, so it will work fantastically with just about any 400~450MHz wireless receiver/transmitter.
Jargon buster
Plain-language definitions for the technical terms used above.
- LoRa
- LoRa is a long-range, low-power radio technology often used for telemetry and remote sensors. It matters here because the connector and pinout are compatible with some LoRa telemetry products, even though this module uses Bluetooth instead.
