Product introduction 
 

Lite link is a mini version of the radio audio interface. Unlike most interface on 
the  market,  the  lite  link  has  a  PCB  size  of  only  5*5cm.  The  following  is  the 
difference between litelink and other products. 
1. The price is very cheap, the price can only buy a USB-COM cable 
(If  you  go  to  the  electronics  market  and  don't  know  how  to  do  it,  you  will  be 
pitted) 
2. Provides a 4-ring stereo jack for easy connection to hardware 
(You  can  directly  use  the  4-ring  male-to-public  connection  single-interface 
computer, as well as mobile phones, Android or other tablet devices) 
3. With TTL write frequency interface 
(The TTL write frequency interface is provided in the upper right corner of the 
board, which is convenient for you to write to GP88)
