GEPRC ELRS Nano DUAL 2.4G C3 True Diversity Receiver
GEPRC ELRS Nano DUAL 2.4G C3 True Diversity Receiver — Two Antennas, a Solid Link in Any Orientation
The GEPRC ELRS Nano DUAL 2.4G C3 True Diversity Receiver is a new generation dual-antenna diversity receiver built on the open-source ExpressLRS protocol. Two independent SX1281 RF chips and a top-tier ESP32-C3 processor run two separate 2.4GHz receiving links at once, so the GEPRC ELRS Nano DUAL 2.4G C3 True Diversity Receiver keeps a stable connection even when one antenna's line of sight is blocked. A built-in TCXO temperature-compensated oscillator keeps the signal frequency rock solid regardless of temperature swings, while the whole board weighs only 1.1g and measures just 17x13mm. With a refresh rate of up to 1000Hz and an SH1.0 plug-and-play connector, it is built for pilots who want every bit of control latency shaved off without adding extra weight to the build.
True Diversity for a Stable Link
Instead of switching between antennas, the receiver's two SX1281 chips listen on both antennas at the same time in true diversity mode, so the strongest signal is always the one being used. The two T-antennas are mounted at an angle to each other for omnidirectional reception, cutting the risk of signal loss from an antenna that momentarily faces away from the transmitter and adding real redundancy to the RC link.
Built-In TCXO for Frequency Stability
A temperature-compensated crystal oscillator keeps the receiver's operating frequency stable across hot and cold conditions alike, avoiding the frequency drift that can otherwise creep in as electronics heat up during a flight. The result is a more consistent, safer RC link from a cold start through a hard-flown pack.
Ultra-Lightweight with Low Control Latency
At just 17x13mm and 1.1g, the receiver adds almost nothing to your build's weight, which matters directly for a racing or freestyle quad's power-to-weight ratio. Paired with a refresh rate of up to 1000Hz, it delivers the ultra-low control latency that competitive pilots rely on for sharp, immediate stick response.
GEPRC ELRS Nano DUAL 2.4G C3 True Diversity Receiver Key Features
Dual SX1281 Chips
Two independent RF chips run two receiving links at once, the hardware base for true diversity and Gemini mode.
Omnidirectional Reception
The angled dual-antenna layout reduces blind spots and keeps the link stable regardless of the aircraft's orientation.
Integrated TCXO
Temperature-compensated oscillator for a stable operating frequency in extreme heat or cold.
Up to 1000Hz Refresh
A 25Hz–1000Hz refresh range gives you the ultra-low latency needed for competitive racing and freestyle.
Compact & Ultra-Light
17x13mm and only 1.1g, so it barely affects your build's overall weight.
SH1.0 Plug-and-Play
A 4-pin SH1.0 connector for a fast, clean install — no soldering required, though solder pads remain available.
WiFi Firmware Upgrade
Update the ExpressLRS firmware wirelessly over the receiver's built-in WiFi module, no cable or programmer needed.
RGB Status LED
A built-in RGB indicator light shows the receiver's binding and connection status at a glance.
GEPRC ELRS Nano DUAL 2.4G C3 True Diversity Receiver Suitable Applications
Its light weight, high refresh rate, and true-diversity reliability make the GEPRC ELRS Nano DUAL 2.4G C3 True Diversity Receiver a natural fit for 2.4GHz ExpressLRS builds where every gram and every millisecond counts:
- FPV racing quadcopters, where ultra-low latency and a rock-solid link matter most
- Freestyle multirotors that need a reliable, redundant RC link during aggressive flying
- Lightweight and compact builds (including sub-250g quads) where every gram of payload matters
