    Hi, I want to connect a device which sometimes need 5v 2a power.
    I plan to use an IC for boosting the vcc of serial 3.3v up to 5v.
    But what's the max current output the serial vcc pin can provide?

    By the way, I find a post about the 5V out of WPJ9344(http://forum.compex.com.sg/88-not-getting-5-0v-on-j5-of-compex-wpj344hv-embedded-board).
    Any similar method can applied to WPJ9531?

    Any feedback is appreciated.

    Best regards

    Dear Ming,

    The WPJ531 board cannot supply 5V to the MiniPCIe card.

    The WPJ344 and WPJ558 can supply 5V to the card. The way to do it is by the J5 jumper setting.

    Best,
    Winston

  3. Ok. Thanks
