HW-237 2.4GHz NRF24L01+PA+LNA SMA Wireless Transceiver Module with Antenna
HW-237 2.4GHz NRF24L01+PA+LNA SMA Wireless Transceiver Module with Antenna is the latest in RF modules. This module uses the 2.4GHz transceiver from Nordic Semiconductor, the NRF24L01+. This transceiver IC operates in the 2.4GHz band and has many new features! Take all the coolness of the nRF2401A and add some extra pipelines, buffers, and an auto-retransmit feature – very nice!
This board features a reverse-polarized SMA connector for maximum RF range. It also has PA and LNA circuits. With the external antenna, it can reach a longer distance than the one without these parts.
This module comes with a 2.4G antenna (2DB), with a 250Kbps transmission rate in the open air; it can reach a communication distance of 800-1K meters.
