Technical Highlights

Sub-GHz ExpressLRS Receiver

The GEPRC ELRS Nano 915M PA500 is a single-antenna ExpressLRS receiver available for 915MHz FCC or 868MHz EU operation. The correct regional version must be selected for the intended transmitter system and operating location.

Up to 500mW Telemetry Power

An integrated power-amplifier chip provides telemetry return power of up to 500mW. This specification refers to the receiver-to-transmitter telemetry link and must not be interpreted as FPV video-transmission power.

TCXO Frequency Stability

A temperature-compensated crystal oscillator helps reduce frequency drift as operating temperature changes, supporting a more stable sub-GHz control link.

25–200Hz Refresh Rate

The receiver supports refresh rates from 25Hz to 200Hz. The selected packet rate should match the transmitter configuration, required response characteristics and link conditions.

Compact 1.9g Receiver

The receiver measures 13 × 23 × 5.5mm and weighs 1.9g without the antenna or cable, supporting compact FPV and RC installations.

WiFi Firmware Upgrade Support

A built-in WiFi antenna supports wireless firmware updates. The receiver uses the GEPRC Nano 915M PA500 RX firmware target and should be flashed with the appropriate regional configuration.

IPEX1 T-Type Antenna Connection

The receiver uses an IPEX1 antenna connector and is shown with a long T-type antenna. The antenna should match the selected 915MHz or 868MHz regional version.

Regional Version Selection

Select the 915MHz FCC version for a compatible 915MHz ExpressLRS transmitter system and permitted operating region.
Select the 868MHz EU version for a compatible 868MHz ExpressLRS transmitter system and permitted operating region.
Do not treat 915MHz and 868MHz as simultaneously active operating bands.
Confirm that the receiver firmware target, regulatory domain and antenna match the selected regional version.
Use only frequencies and telemetry-power settings permitted by local radio regulations.

Flight Controller Connection

Connect the receiver to a regulated 5V supply and ground.
Connect receiver R to the selected flight-controller UART TX connection.
Connect receiver T to the selected flight-controller UART RX connection.
Enable Serial RX on the selected UART and select CRSF as the serial receiver protocol.
Verify the connector pinout and wire order before applying power.

Installation Notes

Connect a suitable 915MHz or 868MHz antenna before operating the receiver at elevated telemetry power.
Do not power the receiver directly from battery voltage; use a regulated 5V supply.
Keep the antenna away from carbon fibre, batteries, ESCs, motors and high-current wiring.
Secure the receiver and antenna cable so vibration cannot load the IPEX1 connector.
Provide airflow around the heatsink when operating with high telemetry-power settings.
Confirm transmitter and receiver firmware compatibility before binding.
Complete binding, failsafe, telemetry and control-range checks before flight.

Important Product-Type Notice

This product is an ExpressLRS radio-control receiver. Its 500mW rating describes telemetry return power; it does not transmit analog or digital FPV video.

FAQ

Is this product only a T-type antenna?

No. The product is the complete GEPRC ELRS Nano 915M PA500 receiver. The long T-type antenna connects to the receiver through its IPEX1 antenna connector.

Is the 500mW rating video-transmission power?

No. The 500mW rating is the receiver's maximum telemetry return power. The product does not transmit analog or digital FPV video.

What is the difference between the 915MHz and 868MHz versions?

The 915MHz version is intended for the appropriate FCC regional configuration, while the 868MHz version is intended for the appropriate EU configuration. Select the version that matches the transmitter, firmware and local regulations.

What input voltage does the receiver require?

The receiver requires a regulated 5V supply. Do not connect unregulated battery voltage directly to the 5V input.

Which flight-controller protocol should be selected?

Connect the receiver through a compatible UART and select CRSF as the serial receiver protocol in the flight-controller configuration.

What refresh rates are supported?

The receiver supports refresh rates from 25Hz to 200Hz. The available setting should be selected to match the ExpressLRS transmitter configuration and required link characteristics.

Does the receiver support wireless firmware updates?

Yes. The receiver includes a built-in WiFi antenna for wireless firmware updates. Use the GEPRC Nano 915M PA500 RX firmware target and the correct regional configuration.

What are the receiver dimensions and weight?

The receiver measures 13 × 23 × 5.5mm and weighs 1.9g without its antenna or connection cable.

B2B Procurement FAQ

Which frequency version should be specified in an inquiry?

Please specify either the 915MHz FCC version or the 868MHz EU version, together with the required quantity and destination market.

What model name should be used for quotation?

Use the complete model name GEPRC ELRS Nano 915M PA500 Receiver and identify the required regional frequency version.

Should the antenna be treated as a separate product?

The supplied material presents the T-type antenna with the receiver. Exact package contents and any antenna-only ordering option must be confirmed during quotation.

What should be confirmed before a bulk order?

Confirm the frequency version, firmware target, telemetry-power requirements, antenna configuration, connector cable, package contents, stock status, lead time and applicable compliance documentation.

Can OEM or custom-logo services be promised from the supplied images?

No. The archive includes general OEM and company promotional images, but these do not establish product-specific customization terms. Any customization, MOQ or branding requirement must be confirmed during quotation.
