Ditch the external wires and simplify your micro build! The Sub250 Lite ELRS 2.4G Receiver brings the incredible low-latency performance of ExpressLRS to the tightest Tiny Whoops and toothpick frames by utilizing a highly efficient Integrated SMD Ceramic Antenna.
Zero Antenna Hassles
Mounting and protecting receiver antennas on 65mm or 75mm micro frames can be incredibly frustrating. The Lite version solves this by building a durable, surface-mounted ceramic antenna directly onto the board. This eliminates the risk of props snipping your antenna wires in a crash, making it the ultimate durable choice for indoor racing and tight freestyle whoops.
Lightning-Fast 1000Hz Refresh Rate
Despite weighing just 0.7g, this tiny receiver packs a massive punch. Powered by the robust ESP8285 and SX1281 chips, the Sub250 Lite supports a blistering 1000Hz maximum refresh rate. This translates to a locked-in, hyper-responsive connection between your transmitter sticks and your drone’s motors.
Wireless WiFi Updates
Say goodbye to complicated Betaflight passthrough flashing. The Lite receiver features built-in WiFi. Simply power the receiver, connect to its WiFi network from your smartphone or computer, and update your firmware completely wirelessly via the ExpressLRS Web UI.
