1. BRIEF INTRODUCTION   

HLK-RM08K  is  a  new  low-cost  embedded  UART-ETH-WIFI  module  (serial 

port - Ethernet - Wireless network) developed by Shenzhen Hi-Link (HK) co., Ltd. 

          The  product  is  a  low  power  consumption  WIFI  module,supports  EEE802.11b/g/n  wir

eless  protocol  with  small  size  and  smart  use,ully  transparent  transmission  UART  module,  b

uilt-in  TCP  /  IP  protocol  stack,  enabling  users  short  development  cycle.  It  just  needs  host

  computer,WEB  browser  or  APP  to  set  up  parameters,  making  the  connection  between  UA

RT  and  network. 

  HLK-RM08K 

has  stable  performance  and  flexible  use,  meeting  kinds  of 

requirements of users. and strong technical supports could be provided. Also, it could 

be customized,such as WEB interface ,mobile phone app and so on.
