I have an RC airplane gyro, with a little, female header plug, that looks like it slides over a pin header, 4 pins, --dimensions unknown, but it looks simple and inexpensive it's definitely smaller than .1 inch, but I haven't neasured it yet... this might work, if someone can give a part number for this... ----- Original Message ----- From: "Mike Harrison" To: Sent: Monday, February 24, 2003 10:07 AM Subject: Re: [EE]: Compact connector for serail port I think there is a standard-ish micro-USB connector used on some digital cameras - probably cheap but might be a problem getting in small quantities. The small size IEEE1394 firewire connectors may also be worth a look. And of course there is mini-DIN, but not much smaller than RJ45.
