Detail smallest NRF24L01 smd 2.4GHz Wireless Module Mini Power enhanc Version
The mini size NRF24 (TW) wireless board, 12*18mm, orignal nordic NRF24L01 compatible, all the same way of use, the only two differences with original one are: NRF24 can provide higher transmission power up to 7dbm (0dbm original) but same power computation on same transmission power level, also this one is much cheaper!
Specification:
Voltage: 1.9-3.6V Sensitivity: 2Mbps -83dB, 1Mbps 87dB, 250kbps -96dB. Receiving current: 2Mbps 15mA, 1Mbps 14.5mA, 250kbps 14mA Standby current: 15uA Power off current: 700nA Operation temperature: -20 ~ +55 degree. On board PCB antenna, transmission distance reach 240M in open area, but 2.4G frequency is not good to pass through walls, also interfere by 2.4G wifi signal significantly.
