3DR Radio 2 kit

$155.90

The 3DR Radio 2 is a professional, cost-effective connectivity bridge developed and manufactured by 3DR in collaboration with Nimbus Robotics AI. It enables HaLow (Wi-Fi IEEE 802.11ah) connectivity for drones and robotics applications.

Operating in the Sub-1 GHz band, 3DR Radio 2 offers long-range communication, low power consumption, and strong signal penetration — ideal for industrial, UAS, energy, and robotic applications. Features an RF switch and integrated Power Amplifier (PA) in the SoC, delivering up to 23 ± 2 dBm output power.

The device can be powered through a USB connection or via the +5V and GND pins using any Telemetry port connector.
