The mini NRF24 (TW) wireless board, 12x18mm, 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 less expensive.

• 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
