Experience the unmatched range, ultra-low latency, and rock-solid connection of the ExpressLRS protocol with the Sub250 Nano ELRS 2.4G Receiver. Engineered specifically for micro drones, Tiny Whoops, and space-constrained toothpick builds, this receiver is available in two specialized versions to perfectly match your build requirements.

Choose Your Version: Standard vs. Pro

• Standard Nano (0.6g): The ultimate weight-saver. Measuring just 14x11mm, this receiver tucks into the tightest micro canopies. It features 17mW of telemetry power, making it the perfect choice for indoor whoops and ultra-lightweight park flyers.

• Pro Nano (0.7g): Built for maximum reliability and range. The Pro version upgrades to a TCXO (Temperature Compensated Crystal Oscillator), ensuring your frequency remains locked in and perfectly stable regardless of extreme heat or cold. It also features a built-in PA+LNA amplifier, boosting telemetry power up to 100mW so your remote always has a strong signal coming back from the drone.

Lightning-Fast 1000Hz Refresh Rate

Both versions are powered by robust ESP8285 and SX1281 chips, supporting a blistering 1000Hz maximum refresh rate. This translates to a locked-in, hyper-responsive connection between your transmitter sticks and your motors, giving you the competitive edge in racing and the precise control needed for tight freestyle gaps.

Wireless WiFi Updates

Say goodbye to complicated Betaflight passthrough flashing. Both the Standard and Pro receivers feature built-in WiFi. Simply power the receiver, connect to its WiFi network from your phone or computer, and update your firmware completely wirelessly via the ExpressLRS Web UI.
