GEPRC ELRS Nano DUAL 2.4G C3 True Diversity Receiver (ExpressLRS) TCXO, WiFi Firmware Upgrade, 1000Hz

Overview

The GEPRC ELRS Nano DUAL 2.4G C3 True Diversity Receiver is a receiver based on the ExpressLRS open source project, featuring true dual-antenna diversity, low latency operation, and up to 1000Hz refresh rate. Dual independent RF receiving links and an optimized antenna layout provide omnidirectional reception for a more stable control link than typical single-antenna receiver systems.

It uses a temperature-compensated crystal oscillator (TCXO) to reduce frequency shift from temperature changes, and supports firmware upgrade via Wi-Fi.

Key Features

• True diversity receiver with two independent RF receiving links
• Dual SX1281 chips; ESP32-C3 chip
• Integrated TCXO crystal oscillator
• Compact size: 17 x 13 mm; weight: 1.1 g (RX only)
• Refresh rate: 25Hz-1000Hz
• RGB indicator light for status
• SH1.0 connector support or soldering installation
• Firmware upgrade via Wi-Fi
• Supports true diversity mode and Gemini mode

Specifications

RX Operating Bands

Wiring

• Standard FC wiring: GND to GND, 5V to 5V, TX (RX side) to RX (FC), RX (RX side) to TX (FC)
• Betaflight standard connector wiring is different from the ELRS standard; always verify the FC-to-RX connection order before plugging in to avoid damage caused by reversed polarity.

What’s Included

• 1 x ELRS Nano DUAL 2.4G True Diversity Receiver
• 2 x 2.4G T-Antennas (ipex1 80mm)
• 1 x Receiver silicone cable (SH1.0 4pin 100mm)
• 1 x Heat shrink tube
• 1 x User manual

Details

The GEPRC ELRS Nano DUAL 2.4G true diversity receiver pairs a compact board with dual ANT1/ANT2 antennas and integrated TCXO.

The GEPRC 2.4G ELRS nano receiver uses a dual-antenna true diversity layout with ANT1 and ANT2 connections for more stable reception.

The ELRS Nano Dual receiver is listed as 17×13mm and 1.1g, supports up to a 1000Hz refresh rate, and can be connected via SH1.0 plug or solder pads.

The built-in TCXO helps maintain stable frequency operation across changing temperatures.

The GEPRC ELRS Nano Dual 2.4G C3 receiver features an RGB status LED, an SH1.0 connector, and Wi‑Fi firmware upgrade support.

The GEPRC ELRS Nano Dual receiver connects to the flight controller with GND, 5V, TX, and RX, and the Betaflight connector pin order differs from the standard wiring.

The ELRS Nano Dual receiver supports 2.4GHz operation, with no 915MHz or 915MHz+2.4GHz Gemini dual-band mode listed.

The GEPRC ELRS Nano DUAL 2.4G receiver measures 17×13mm, runs on 5V input, and supports a 25–1000Hz refresh rate.

GEPRC’s ELRS Dual 2.4G C3 nano receiver uses two antenna ports and clearly labeled G, 5V, T, and R pads for straightforward wiring.

Dual ANT1/ANT2 antenna connectors and clearly labeled G, 5V, T, and R pads make wiring this 2.4G ELRS nano receiver straightforward.

The GEPRC 2.4G TD receiver uses two antennas on ANT1 and ANT2 to support true diversity placement in compact FPV builds.

The GEPRC ELRS Nano Dual 2.4G receiver kit includes two 2.4G T-antennas, a 4-pin SH1.0 receiver cable, and heat shrink tubing for installation.
