[Introduction]：E160-TxMS1 is an extremely low-cost OOK/ASK modulation 315MHz/433.92MHz wireless transmitter module developed by Ebyte. It uses high-performance RF chips and narrowband matching networks to improve harmonic suppression capabilities. It has small size, low power consumption, high performance, wide voltage, and high power. It has passed FCC and CE certification and is suitable for button battery power supply. It is suitable for small home appliance remote control, toy remote control, access control system remote control, tire pressure detection system, wireless data transmission and other application scenarios
