Title: RS232 Modules Post by: TZtech on September 03, 2012, 06:48:42 PM Found these on EBAY recently - Cheaper and more compact alternative to the modules we have been using.
Can be built into the micro - machine harness and insulated with some heatshrink. http://www.ebay.com/itm/Serial-Port-Mini-RS232-to-TTL-Converter-Adaptor-Module-Board-MAX3232-115200bps-/251103811631?pt=LH_DefaultDomain_0&hash=item3a76f4182f (http://www.ebay.com/itm/Serial-Port-Mini-RS232-to-TTL-Converter-Adaptor-Module-Board-MAX3232-115200bps-/251103811631?pt=LH_DefaultDomain_0&hash=item3a76f4182f) Title: Re: RS232 Modules Post by: TZtech on November 22, 2012, 01:45:07 PM Hi All
Finally recieved these from Deal Extreme (The EBAY seller I linked to does not ship here). These things are tiny. Pictured here next to the modules we have been using up to now.

No real reason fot it to be so small - Just wanted to see how compact I could make it. Title: Re: RS232 Modules Post by: SLOTMAN on December 29, 2012, 02:44:08 PM I found this, how could anyone pass it up at this price :208-

I have one of the 4 port versions and it works great.
