2.4G Transceiver Module NRF24L01 with Ceramic Antenna
Product Description
2.4G RF Transceiver Module with Ceramic Antenna
Module introduction
Based on Nordic's NRF24L01 wireless transceiver chip design, the DL-24N-S is a compact 2.4G wireless RF module with excellent performance and long distance. This 2.4G RF module is widely used in the fields of smart home, toy airplane model, and close-range data transmission control. The sensitivity can reach -82dbm@2M, the maximum transmission rate can reach 2Mbps, and the output power can be set in four steps from -20dbm to 0dbm through the register. The module integrates all RF-related functions. Users do not need to have a deep understanding of RF circuit design, they can use this module to easily develop stable and reliable wireless products, shortening the development cycle.
This RF module adopts the half-hole interface mode of the stamp side, which can not only meet the customer's SMT application, but also realize the horizontal and vertical welding through the pin row. Small size, easy to apply to portable products, and the module uses high-precision, high temperature stability of the crystal, the module has a very high cost performance, suitable for high-volume applications.
