![enter image description here][1] ![enter image description here][2] **Description:** This module uses the newest 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! Please note: We now populate these boards with the nRF24L01+. The ‘+’ version of the IC has improved range, sensitivity, and data rates. The command set is backward compatible with the original nRF24L01. **Dimensions**: 0.8x0.9" **Features:** On-board 3.3V LDO Regulator (3.3 to 7V supply allowed) On-board ceramic 2.4GHz Antenna 100m Range at 250kbps 250kbps to 2Mbit Data Rate Auto Acknowledge Auto Re-Transmit Multiceiver - 6 Data Pipes 32 Byte separate TX and RX FIFOs 5V tolerant input pins Software selectable channel from 2400MHz to 2525MHz (125 Selectable channels) Minimum number of external components Pins broken out : VCC, CE, CSN, SCK, MOSI, MISO, IRQ, GND Lots of application notes and support on Nordic Semiconductor Website For more detail and Documents, Please visit: http://www.sparkfun.com/products/691 [1]: /editor/20160717/578b9f849a486.png [2]: /editor/20160717/578b9f8aefbb6.png
