Description
The HappyModel EP2 TCXO takes the ultra-compact ceramic antenna design of the EP2 and boosts its reliability with a TCXO oscillator. This makes it the perfect choice for high-performance Tinywhoops and Toothpicks that generate a lot of heat in tight canopies.
With the TCXO, you get the durability of the ceramic antenna combined with the frequency precision of a pro-grade receiver. No external antennas to break, no frequency drift to worry about.
Key Features:
-
TCXO Stability: Reliable link in high-heat micro builds.
-
Ceramic Antenna: Durable and compact (no loose wires).
-
Tiny Footprint: Perfect for whoops and micro drones.
-
Performance: Same high refresh rates as the standard EP2.
EP2 ELRS receiver is the hottest Tiny ExpressLRS receiver since it was released. Now the new TCXO version EP series receiver apply “temperature compensated crystal oscillator”, accurate frequency and excellent performance in extreme temperature environments make these TCXO much reliable.
