Product ID


The BC3602 is a high performance and low cost FSK/GFSK RF transceiver IC from Holtek that operates in the license-free 315MHz, 433MHz, 470MHz, 868MHz, and 915MHz ISM (Industrial, Scientific and Medical) bands. It features low RX current that makes it suitable for battery-powered products.

This module BM3602-04-1 is a BC3602 based FSK/GFSK RF transceiver module operating at 433MHz. It communicates with the host MCU via a 3-wire or 4-wire SPI interface.

If you need a higher power version, please refer to BC3601 and BM3601-04-1. The BC3601 and BM3601-04-1 have higher maximum output power but the RX current consumption is also higher.


  1. This product does not include an antenna, you need to prepare the antenna that match your need.
