SparkFun Transceiver Breakout - nRF24L01+ (RP-SMA) [Discontinued] Connector_DB9 3V LDO powering the ESP32The nRF24L01 module is the latest in RF modules from SparkFun. 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. Please remember, you will need a
