We are evaluating ROC-RK3566-PC for our product, we have some queries from hardware peripherals support and Android-11:

  1.    Does it support RS232 ?

  2.    Firefly provides antenna. What is the antenna length?  Can we customize antenna length?

  3.    Will firefly share android 11 source code with us for customization or configuration modification? If yes, from where ?

  4.    Does base Android 11 provided by Firefly support future OTA? If so, till when Firefly will support OTA ?

  5.    Do you have eMMC flash process for mass production?
