Introduction

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.

If you need more technical information, or utility example, please feel free to contact us by eBay message or by INHAOS website. All customers can get technical support on this module from INHAOS.
