I had a breakout board with DS1621 on it with 4.7Kilo ohms pullups (to 3.3V) on SCL and SDA.<br /><br />BUT yes, RPi already has 1.8K pullups, so you don't need to supply them externally. DS1621 will work without it too.Anurag Chughhttps://www.blogger.com/profile/15390575283968794206noreply@blogger.comtag:blogger.com,1999:blog-8517901213371477159.post-89495078115394387062013-10-10T18:46:01.101+05:302013-10-10T18:46:01.101+05:30Hi.

Would it require additional resistors or perhaps external power?<br /><br />Thank youAnonymousnoreply@blogger.com
