2.4GHz Wireless Transceiver Module – Si24R1 SMD


Package Includes

  • 1x SMD Si24R1 2.4GHz Wireless Transceiver Module

Availability: 4 in stock

This module is a compact surface mount dev board for the Si24R1 2.4GHz RF transceiver chip – a cheaper alternative to Nordic’s popular nRF24L01+. Looking to compete directly with Nordic, the Si24R1 is also an ultra low power (ULP) 2Mbps RF transceiver IC for the 2.4GHz band with many similar specs and features.
