## Description

TX RX 433MHz set for simple wireless transmission between two modules, ideal for IoT projects, remote controls and automation. Includes SYN115 transmitter and SYN480 receiver with ASK OOK modulation, high sensitivity for stable reception, transfer speed up to 10kbps, flexible power supply 1.8-3.6V at the transmitter and 3.3-5.5V at the receiver, compact dimensions for easy integration.
The RF 433MHz set consisting of the SYN115 transmitter and SYN480R receiver represents a compact and efficient solution for wireless data transmission over distance, frequently used in automation applications, remote control, home automation, and alarm systems. The two modules operate together at a frequency of 433MHz, ensuring stable wireless communication with low power consumption.
The SYN115 transmitter integrates the SYN115/F115 chip and operates at a supply voltage between 1.8V and 3.6V, making it ideal for battery-powered projects or directly from the 3.3V pins of development boards. It supports a transfer speed of up to 10kbps and has a sensitivity below 10dBm, ensuring a clean signal at 433MHz frequency. Its small dimensions of 15 x 11.8 mm allow easy integration into compact spaces.
The SYN480R receiver uses the SYN480R chip with ASK/OOK modulation and stands out for its excellent sensitivity of -107dBm, meaning it can receive weak signals from greater distances. The supported transfer rate is 2.5kbps in SWP mode and 10kbps in FIXED mode. The accepted supply voltage is between 3.3V and 5.5V, offering direct compatibility with both 3.3V and 5V logic. The module dimensions are 17.2 x 11.8 mm.
Both modules are fully compatible with Arduino platforms (Uno, Mega, Nano), ESP32, ESP8266, and STM32, allowing quick integration into any project requiring simple wireless communication without frequency licensing.
