Description

GEPRC ELRS Nano 2.4 GHz PA100 Receiver – Tiny Yet Mighty Control

🚀 Overview — Tiny Footprint, Big-Link Confidence

The GEPRC ELRS Nano 2.4 GHz PA100 is a featherweight ExpressLRS receiver built for pilots who need long-range reliability, ultra-low latency, and rock-solid frequency stability in the smallest possible form. At roughly 17×11 mm and about 0.7 g, it slides into micro builds and cinewhoops without upsetting weight budgets, yet delivers a clean, responsive control link that scales from tight indoor lines to open-field cruising.

⚡ RF Performance & Latency — Why It Feels “Locked-In”

Running on the ExpressLRS ecosystem with refresh rates up to 1000 Hz, this receiver translates stick inputs into motor outputs with minimal end-to-end delay. That means crisper propwash recovery, tighter gate entries, and more precise throttle modulation—the stuff that makes a quad feel “plugged in” rather than floaty.

📶 PA + LNA Architecture — Boosting the Link Budget

The integrated PA/LNA front-end (Power Amplifier + Low-Noise Amplifier) enhances both uplink sensitivity and downlink telemetry power (up to 100 mW for telemetry), effectively improving the link budget. Practically, you’ll see cleaner RSSI/LQ at distance, fewer brown-outs in noisy RF environments, and more consistent telemetry for smarter in-flight decisions.

🌡️ TCXO Stability — Staying on Frequency as Temps Swing

A built-in TCXO (Temperature-Compensated Crystal Oscillator) keeps the receiver on-frequency as components warm up or ambient temperatures change. Compared with standard XO designs, TCXO reduces frequency drift, which helps maintain a stable bind and minimize packet loss during long sessions or hot summer races.

🧠 Chipset & Protocol — Lean, Fast, and Open

The Nano PA100 couples an ESP8285 MCU with a Semtech SX1281 2.4 GHz transceiver—hardware known in the ELRS world for snappy packet timing and robust FEC. You get the full open-source ExpressLRS benefits: frequent improvements, flexible binding methods, and parameter tuning without vendor lock-in.

🔌 Power & Wiring — Keep It Clean, Keep It Cool

Designed for a standard 5 V input, the receiver integrates cleanly with common FC 5 V rails. Use short, twisted signal/ground runs to mitigate noise, and avoid routing next to high-current ESC phases. Proper power discipline yields lower RF noise and fewer failsafe spikes when you punch out.

📡 Antenna & Placement — Free the RF

The IPEX1 antenna lead makes positioning simple. For best range, keep the active element away from carbon, batteries, and VTX cans; avoid tight coils and hard bends; and orient for polarization diversity relative to your TX antenna. Small changes in routing can net big gains in RSSI/LQ stability.

🔄 Firmware & Binding — Quick Updates, Field-Friendly

With Wi-Fi OTA updates, you can flash new ELRS builds or change RX options without a bench setup—handy for the field. Binding is straightforward via bind phrase workflows or classic bind modes, so you can standardize fleets and swap frames with minimal fuss.

🧩 Mounting & Integration — Micro-Ready

At sub-gram weight and micro PCB dimensions, the Nano PA100 tucks neatly into tight ducts and canopy bays. The included silicone leads and heat-shrink help you build clean, rattle-free installs that survive crashes and weather vibration better than loose or rigid runs.

🏁 Ideal Use Cases — Where It Shines

Racing quads needing 1000 Hz responsiveness and minimal latency
Cinewhoops/micros where weight and space are at a premium
Long-range park flyers that benefit from TCXO stability and PA/LNA headroom
Education/DIY labs standardizing on open-source ELRS for flexibility

✅ Compatibility Snapshot (Prose)

Works within the 2.4 GHz ISM band on ExpressLRS. Plays nicely with modern ELRS transmitters and radios supporting ELRS modules; uses a standard 5 V supply and serial (CRSF-style) receiver connection on most FCs.

📦 In the Box (Prose)

Receiver module, 2.4 GHz antenna with IPEX1 connector, silicone wires, 4-pin connector, heat-shrink, and a quick guide—enough to wire, protect, and tune the install.

📏 Key Specs (Prose)

Ultra-compact 17×11 mm PCB at ~0.7 g; 2.4 GHz operation; PA/LNA front-end with telemetry to ~100 mW; TCXOfrequency control; 5 V supply; Wi-Fi OTA updates; up to 1000 Hz packet rate; IPEX1 antenna interface.

⭐ User Reviews

★★★★★ Jordan M. – Long-Range Pilot

“TCXO + PA/LNA keeps the link clean where my older RXs struggled. Telemetry holds further than I expected.”

★★★★★ Mia L. – Freestyle Flyer

“The 1000 Hz mode makes stick input feel instant. Micro builds finally fly like my 5-inch.”

★★★★☆ Alex P. – Frame Designer

“Tiny and light—fits ducts without drama. I’d love a pre-solder pigtail option out of the box.”

★★★★★ Emily R. – Cinewhoop Operator

“Stable RSSI around metal and glass. The frequency stability shows up in fewer signal ‘wobbles’ on set.”

★★★★☆ Ravi S. – Park Cruiser

“Wi-Fi updates in the field = awesome. A second spare antenna would make it perfect.”

★★★★★ Kevin T. – Tech Reviewer

“Measured latency is consistently low. The link budget feels a tier above other nano receivers I’ve tried.”

★★★★☆ Zoe B. – Racer

“Bound via bind phrase in seconds. Rock-solid at race power levels.”

★★★★★ Sam W. – ELRS Newcomer

“Setup was simpler than I feared. Clear guide, quick bind, and it just works.”

★★★★★ Lena K. – Micro Builder

“Finally a sub-gram RX that doesn’t compromise range. Ideal for my 2–3″ builds.”

★★★★★ Omar H. – Club Instructor

“I standardize students on this RX—reliable, predictable, easy to update. Cuts down troubleshooting time.”
