Frequently Asked Questions

Q: What is the difference between the SYN115 and SYN480R chips in this 433MHz RF module?

A: The SYN115 is the transmitter IC — it modulates and transmits data at 433MHz using ASK/OOK encoding. The SYN480R is the corresponding receiver IC that demodulates the incoming 433MHz ASK/OOK signal. Together they form a complete one-way RF wireless link. You can purchase them individually or as a matched set.

Q: What supply voltage does this 433MHz RF transceiver module require?

A: This module operates on a supply voltage of 1.8V to 3.6V, making it compatible with 3.3V microcontrollers and development boards such as Arduino (with a voltage divider), ESP8266, ESP32, and STM32 platforms right out of the box.

Q: What are typical use cases for a 433MHz ASK OOK RF wireless module?

A: Common applications include wireless remote controls, home automation systems, IoT sensor nodes, keyless entry systems, wireless data loggers, and any project requiring short-to-medium-range low-power RF communication between two microcontroller-based devices.

Q: How small is the PCB for this RF module?

A: The PCB measures just 15mm × 11.8mm in an SMD package, making it one of the most compact 433MHz RF solutions available — ideal for embedding directly into finished product enclosures or tightly packed custom PCB designs.
