[Introduction]：E160-R4MS1 heterodyne receiver module, developed by EBYTE, is a low-cost OOK/ASK modulation 315MHz/433.92MHz wireless receiver. It features a high-performance RF chip with built-in image rejection, excellent anti-interference, and precise weak signal detection. With a compact size, low power consumption, high sensitivity, wide voltage range, and strong protection, it is FCC and CE certified and suitable for coin cell battery power. Ideal for applications in remote controls for small appliances, toys, access control systems, tire pressure monitoring systems, and wireless data transmission.
