RF-2400P 2.4GHz Wireless Transceiver - 2.4G RF Module

BK-2421 is a stable high-performance 2.4G wireless module. In China, over 10KK products use this chip monthly. To let more people know about this chip, we have released the RF-2400 series modules.

RF-2400 Series 2.4GHz Wireless Transceiver Module



Before RF-2400 series wireless module was released, the best modules of 2.4G RF Transceivers are based on Nordic nRF24L01+. Now RF engineers have more choices by RF-2400 series modules, which were produced by Beken BK-2421 chip, with the same performance but lower cost than nRF24L01+.

BK-2421 is a stable high-performance 2.4G wireless module. In China, over 10KK products use this chip monthly. To let more people know about this chip, we have released the RF-2400 series modules.  


RF-2400 module has three series

RF-2400W: with DIP 2x4pin Connector, Wiggle antenna, for DIY and performance verification phase.

RF-2400P: using DIP 2x4Pin Connector, PIFA antennas, for DIY and performance verification phase.

RF-2400-V3: use SMT chip package.


RF-2400W and RF-2400P has the same dimensions and electrical interfaces, and different antenna, Wiggle Antenna is about 1dB lower than PIFA with smaller volume. You can purchase RF-2400W and RF-2400P to measure to select the appropriate antenna design for mass production.RF-2400-V3 can use SMD reflow, and is available for quantity production with smaller size and lower cost.


We usually recommend customers to use RF-2400W or RF-2400P for products design verification. You can directly use RF-2400-V3 for formal product design. INHAOS has already done fully performance tests of the three modules to ensure no technical risks.
