2.4G Wireless Transceiver Module with NRF24L01 Chip
Designed base on Nordic's NRF24L01 wireless transceiver chip, DL-24N Serial RF modules are 2.4g wireless modules with small size, excellent performance and long distance, which are widely used in intelligent home, toys, model airplane, and the field of close digital transmission control. The sensitivity can reach -82dbm@2m, the highest transmission rate can reach 2Mbps, and the output power can be configured in four levels from -20dbm to 0dbm through registers.
This wireless module has integrated all radiofrequency related functions, and users can easily develop wireless products with stable performance and high reliability directly, which will extremely shorten the development cycle without in-depth understanding of RF circuit design
The module adopts stamp edge and half hole interface design, which can not only meet customers' SMT application, but also realize transverse and longitudinal welding through needle arrangement. The module adopts high precision, high temperature stability crystal, with compact size, is convenient for portable products, and has a very high cost performance, suitable for mass applications
