  • There really should be an option of connecting 5V ( unregulated 500mA USB ) to the FTDI header and keeping the VCCIO at 3.3V. This would make the circuit identical to the FTDI 3V cable. I don't understand the point of providing the current limited 3V ( that is only intended on driving VCCIO ) to the header. One great feature of the FTDI pinout is providing the 500mA at 5V USB raw for powering a projects local LDOs to 3.3V on down. This board only supports that if using 5V IO. According to the FTDI232R spec, the 3V3OUT can only provide 50mA. Plugging this 3V board into an FTDI compatible circuit requiring up to 500mA will certainly cause problems for the FTDI232R. I bought one of these and now realize I must hack it up to use it without damaging it.

  • I use 2 of these plus a Lantronix Xport ( $50 from http://www.semiconductorstore.com/ ) for controlling my Robot wirelessly from my Linux workstation ( Ethernet-_Serial-_Wireless-_Serial ). These modems are incredibly easy to use. Truly a "wireless RS232" pipe. Very pleased. The USB-Dongle + SW I thought was garbage, but using 2 of the BlueSMiRFs to talk to each other has worked out great. My only recommendation would be for Sparkfun to sell them as sets of 2, preconfigured for creating a wireless link to each other.

No public wish lists :(
