in the end i went with this for the router, using an IMD2A for the
two
transistors.
Personally I haven't used RS232 in ages, only different "TTL" serial variants of 5V or 3.3V.
yehh i have to be reaasonably compatible with RS232, as this is actually going to have a 9-pin header on it. although the only thing it will be connected to in most cases is one of those... yup, USB serial converters.
Why don't we include a USB to TTL-Serial chip on the card and/or carrier.
USB-to-TTL.... ah, because that would take out one of the 4 USB ports. in this "product" there's only 1 4-port hub.
No, not on the hub. As as separate usb "slave" port.
USB Host Port-1 -\ USB Host Port-2 -\ |----HUB----[USB-Host SoC UART]--[TTL-USB Slave (USB Serial debug)]--[USB Slave]---[USB-Host/OTG]--[PC,Tablet,etc.] USB Host Port-3 -/ USB Host Port-4 -/
