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
