Description

The nRF24L01+ Mini module is a RFRadio Frequency transceiver designed to work in the 2.4GHz ISMIndustrial, Scientific, and Medical radio bands band from 2.400GHz to 2.525GHz with as many as 126 communication channels. This is a miniaturized SMDSurface Mount Device breakout of the nRF24L01+ with a size of 18mm x 12mm (0.47in x 0.71in) and pin spacing of 1.27mm (0.05in), which is smaller than the standard generic nRF24L01+ module that has a size of 28.5mm x 15.2mm (1.12in x 0.60in) with 2.54mm (0.1in) breadboard pin spacing. The only difference between the generic and Mini board is the size and the pin spacing.

The range of this module varies, with conflicting information on the internet, but is generally from 50 feet up to 200 feet in open air with a programmable RFRadio Frequency power output up to 0dBmDecibel-milliwatts (dBm) is a power level that expresses decibels in terms of milliwatts on a logarithmic scale. (1mW). Transmission communication is half-duplex with GFSKGaussian Frequency-Shift Keying modulation modulation and has selectable air data rates of 250kbpskilobits per second, 1MbpsMegabits per second, or 2MbpsMegabits per second. The main difference between the NRF24L01 and NRF24L01+ versions of this module is the version without the + has only 1Mbps and 2Mbps baud rates, while the + version can also do 250Kbps. The NRF24L01+ module has built-in hardware CRCCyclic Redundancy Check error detection and an auto-retransmit feature. Data interfacing and control is performed over SPISerial Peripheral Interface (SCKSerial Clock line, MISOMaster In Slave Out (MISO) is the SPI data output line from the slave device, MOSIMaster Out Slave In (MOSI) is the SPI data output line from the master device, CEChip Enable (CE) is the SPI output line from the master device to enable the slave device., CSNChip Select (CSN) is the SPI output line from the master device to indicate that data is being sent. Also referred to as CS or SS (Slave Select).) and is 5V tolerant. It has a power supply voltage ranging from 1.9V to 3.6V DC with 11.3mA (max) transmitting current, 13.5mA (max) receiving current, and a minimum standby current of 26μA.
