Happymodel ExpressLRS Nano 2.4GHz EP1 RX Receiver — Compact and Reliable

Happymodel EP1 RX — a miniature receiver for FPV systems, built on the ExpressLRS protocol. This model combines minimal weight and compact dimensions, making it ideal for small drones, particularly Tiny Whoop. Thanks to its modern hardware platform, the receiver ensures stable communication and low signal latency, essential for quick reactions during racing or acrobatic flights.

Technical Specifications and Features

The receiver operates in the 2400–2500 MHz frequency range, ensuring compatibility with standard 2.4GHz systems. Support for signal refresh rates up to 500 Hz provides ultra-fast transmission of control commands and minimal latency. To save energy and increase communication range, the refresh rate can be reduced to 25 Hz.

Inside, a powerful ESP8285 microcontroller and an SX1280IMLTRT radio frequency chip are installed, responsible for the receiver's stability and accuracy. One of the key advantages is the ability to update firmware via Wi-Fi (OTA), which simplifies maintaining up-to-date software without disassembling the equipment.

Antennas and Package Contents

The kit includes two omnidirectional antennas: one 40 mm long and the other 90 mm long. The combination of different antenna lengths ensures reliable signal reception regardless of the drone's orientation in space, which increases communication stability during maneuvers.

Package Contents:

• 1 x Happymodel ELRS EP1 2.4GHz
• 1 x 40 mm omnidirectional antenna
• 1 x 90 mm omnidirectional antenna

Who It's For

The Happymodel EP1 RX is suitable for both beginner and experienced FPV pilots. The receiver combines ease of integration, small size, and flexible refresh rate settings. Recommended for miniature drones, Tiny Whoop, and other models where weight and communication efficiency are critical.
