Holybro Microhard Telemetry Radio Set V2
Price range: £229.00 through £929.00 Inc. VAT
Long-range, high-speed wireless data link for reliable drone and robotic communication – available in P900, and P400 versions to suit different frequency and range needs.
Holybro Microhard Telemetry Radio integrates a Microhard Pico Series RF module, which is capable of delivering high-performance wireless serial communications in robust topologies, such as Point to Point, Point to Multipoint, and secure Mesh (Mesh only available on P900).
It uses frequency hopping spread spectrum (FHSS) technology, providing reliable wireless asynchronous data transfer between most equipment types that employ a serial interface. The radio can be configured using AT commands through the Data port or using the PicoConfig application through the USB. V2 design now does not require a UART to USB adapter for configuration; a dedicated switch enables easy mode change to change firmware parameters.
P900 Radio operates within the 902-928 MHz ISM frequency band and P400 operates within 410-480MHz. You can select your radio based on your region’s legal frequency band.
