FAQ

Technical Highlights

915MHz ExpressLRS Receiver

RadioMaster identifies the Bandit BR3 as an ExpressLRS receiver in the FCC915 regulatory domain. It receives RC control signals; it does not transmit FPV video.

Adjustable Telemetry Power

Telemetry RF power is LUA-adjustable from 100mW to 500mW. The 500mW figure is the specified maximum, not a continuous fixed setting or a video-transmitter rating.

Dual T-Antenna Arrangement

The BR3 uses two 915/868MHz T antennas connected through IPEX1 antenna interfaces. Its CRSF bus interface supports connection to a suitable flight-control system.

Built-In TCXO

A temperature-compensated crystal oscillator is integrated into the compact 24 × 14.2mm receiver board.

Selection and Installation Notes

Specify Bandit BR3, not BR1, when the 100–500mW adjustable telemetry-power specification is required.
For a conservative installation based on both supplied and current manufacturer specifications, use a regulated 5.0V DC supply. Verify the delivered batch before using a wider input-voltage range.
Use the CRSF interface for the intended flight-controller connection and confirm ExpressLRS frequency and configuration before installation.
The 915/868MHz label describes the specified T antennas; the product listing identifies this receiver as the FCC915 version.

FAQ

Is the Bandit BR3 a video transmitter?

No. It is a 915MHz ExpressLRS RC receiver. Its 100–500mW specification refers to adjustable telemetry RF power, not FPV video transmission.

Is 500mW the receiver's fixed telemetry setting?

No. RadioMaster specifies LUA-adjustable telemetry RF power from 100mW to a maximum of 500mW.

What interface does the BR3 use?

The receiver uses a CRSF bus interface and has two IPEX1 antenna connections.

What supply voltage should be used?

The supplied graphic states 5.0V DC, while RadioMaster's current listing states 4.5–8.4V DC. A regulated 5.0V supply is within both specifications; verify the delivered batch before using the wider range.

B2B Procurement FAQ

What should be specified in a purchase inquiry?

Specify RadioMaster Bandit BR3, the FCC915 version, required quantity and the intended CRSF installation. Request confirmation of the delivered batch's input-voltage specification.

How can BR3 be distinguished from BR1 during sourcing?

Request the exact BR3 model. RadioMaster specifies 100–500mW LUA-adjustable telemetry power, dual T antennas and a 24 × 14.2mm board for BR3; do not apply BR1 specifications to it.

Are price, MOQ and lead time guaranteed?

Price, minimum order quantity, availability and lead time must be confirmed during quotation.
