can it work ? or it is 1.0 and yours is 2.0? Can it use the newest bootloader?
and we can't find "OSC, 6MHz oscillator, 3-pin" , can we use "2-Pin Ceramic Resonator" instead?
And could you open the CAD files of yours board ?
we are in China, the postage is too costly for our workshop , so we want to make it in China, Thank you!
Hi ! I see the "FT232BM USB UART IC Data Sheet" carefully today.
The added circuit of your board is for the "TXLED" and "RXLED" , so they are not a needments of this board , isn't it?
if you want to use "2-Pin Ceramic Resonator" , you need to add two "27pF" between XTIN, XTOUT and GND, then it will work well !
And maybe there is mistake in the CAD file , the USB " + "and "-" are opposition !!! I cut down the "USB head" and link them opposition, then it can work.
sorry about my poor english , there some pic of it :
