    Hi, I know there are two versions of HLK - RM04 (v1 & v2), with different RAM memory and flash memory sizes. Can you specify how much RAM memory does have the HLK - RM04 you are selling? Thank you.


    Thank you for your inquiry.



    Have a nice day!

    Awesome little board. It’s easy-to-use and low-cost solution to add WiFi capability to Arduino or similar microcontroller boards. It allows you to receive/send Ethernet buffers through serial RX/TX pins. Programming is similiar to the standard Arduino Ethernet shield. Unit can be switched to AP or Client. Has build in SER2NET ability to stream your datastream over the net.

    Not really a CON, but including an antenna would be nice.
