RAK553

Module overview

RAK553 supports IEEE802.111a/b/g/n wireless protocol and is an ultra-low power consumption intelligent image transmission module which support the HDMI input.It has small foot print and the easy using feature. The Module support the H.264 codec,the sound processor and is specially designed for accelerating video/audio streaming performance. To fast the evaluation, the user can get the demo Apps on Android, iPhone and other equipment to complete the play and display of audio and video. RAK553 integrates the high-speed serial port to use for transparent in interaction.

RAK553 integrates the WIFI Module ,which support IEEE 802.11a/b/g/n 2×2 MIMO.The module support the remote image transmission.

Dip switch definition

RAK553 There are 6 group Dial-up in the module . ON direction is showing low-level ,marked as 0.
When The Dial-up is on the opposite direcetion ,that is showing high-level,marked as 1.
The dial-up flag order is 1-6,marked as sw1-6.
The function definition is followed :

Sw6 Sw5 Band Channel Central Frequency
1 1 Band1 36 5180
1 0 48 5240
0 1 Band4 149 5745
0 0 165 5825

The default band is Band1. That is to say channel 36. If you are localing on china or Taiwan , you’d better set he channel to Band4 any channel .

Sw1 is using for WPS function . If you want to use this function , you need do the following steps.
1)Whatever the SW1 level , set SW1 into low-level more than 3 second .
2)Then Set SW2 into high-level .
3)The Wifi light will blink.that is showing you have step into the WPS mode.


Use Guidence

Paired with RAK554

RAK553 and RAK554 paired use, the distance can reach 800M. Watch the video method is very simple, as long as the module normally start the case, open the phone, connected to the receiver AP, and then open the phone APP-RAKVideo, you can watch the video.

Of course, RAK553 can also be used alone, but this requires the module to switch to AP mode. We do not recommend this use, because the use of such distance is only about 150M. And our factory default module is used with the RAK554 paired, if you need to use alone, please contact our technical staff.
