Happymodel ELRS 2.4G EP2 TCXO is a receiver for 2.4GHz ELRS. ExpressLRS is an advanced open source RC system with long range, low latency, high refresh rate and lots of useful features. The Happymodel EP2 receiver has miniature dimensions of 10x10mm and an integrated ceramic antenna. Thanks to its small dimensions, the receiver is suitable for smaller 2-4" and racing copters. The TCXO version contains a "temperature compensated crystal oscillator" - a thermally compensated crystal. This ensures a stable oscillator frequency and stable RC transmission even with larger temperature fluctuations.
