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?

and I can't find a "1M resistance" for the "3-Pin Ceramic Resonator" in the board , but there is one in "FT232BM USB UART IC Data Sheet : http://www.ftdichip.com/Documents/DataSheets/ds232b18.pdf"

if we want to use "2-Pin Ceramic Resonator" , could we add two "27pF" between XTIN, XTOUT and GND?

Thank you!
