GEPRC ELRS Nano 2.4G PA100 Receiver

🧠 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.
