Kimpok ELRS RX-720MHz Receiver

Kimpok RX-720MHz ELRS Receiver – Compact Long-Range Control Link for FPV Drones

The Kimpok RX-720MHz is a compact ExpressLRS receiver designed for reliable digital control data reception in FPV drones, RC models, and lightweight UAV builds. It is made for control link communication only, which means it does not receive video or audio. Its main job is to maintain a stable, responsive connection between your radio transmitter and flight controller.

Operating at 720MHz, this receiver is a great choice for hobbyists looking for solid signal penetration, dependable control performance, and improved resistance to interference often found in more crowded frequency bands used in FPV setups. Thanks to its small footprint and low weight, it fits easily into tight drone frames where every gram and every millimeter matters.

Reliable ExpressLRS 720MHz Control Performance

The Kimpok RX-720MHz uses the popular ExpressLRS system, well known in the FPV world for its low latency, high refresh rates, and flexible configuration options. The 720MHz band helps provide a stable RC link in environments where more common frequencies may be more affected by interference.

• ExpressLRS protocol – a trusted RC link standard for FPV drones and radio-controlled models.
• 720MHz operating frequency – designed for stable communication and strong signal penetration.
• Low latency – helps your model respond quickly to stick inputs.
• High refresh rate – smoother, more precise control in the air.
• 15/23MHz band support – compatible with matching ELRS transmitter modules.

Compact Size and Easy Flight Controller Integration

Designed with small FPV builds in mind, the Kimpok RX-720MHz receiver measures just 22 x 11 x 3mm and weighs around 6g. That makes it easy to install in compact frames without adding unnecessary bulk. Connection to the flight controller is handled through a practical 4-pin SH1.0 connector with RX, TX, power, and ground lines.

• Compact dimensions – easy to install in small and mid-size FPV drones.
• Approx. 6g weight – minimal impact on total build weight.
• SH1.0 4-pin connector – quick and convenient wiring to the flight controller.
• RX and TX lines – standard serial communication for easy setup.
• 3.6–5V input voltage – compatible with common FPV power configurations.

SX1276 + ESP8285 Hardware and IPEX1 Antenna Connector

This receiver is based on the SX1276 radio chip and ESP8285, providing the hardware platform needed for dependable ExpressLRS operation. The antenna connects via an IPEX1 connector, giving you the flexibility to use a compatible antenna matched to your frame layout, installation style, and range goals.

• SX1276 + ESP8285 chipset – optimized for ExpressLRS receiver operation.
• IPEX1 antenna connector – a common standard for compact FPV receivers.
• Control data reception only – built for RC link use, not video transmission.
• Easy frame integration – small PCB helps with neat wire and antenna routing.
• Great for custom builds – suitable for FPV, RC, and compact UAV projects.
