The Pro Mini by itself draws 19mA when active and 3.4mA when in power down state.\r\n\r\nThe picture below shows the Pro Mini connected.  I'm using an [nRF24 socket](http://www.ebay.co.uk/itm/191762714694?_trksid=p2057872.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT) which itself draws 3.9mA (for its LED and voltage regulator) and this [nRF24L01](http://www.ebay.co.uk/itm/191784627035?_trksid=p2057872.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT) (pictured below).\r\n\r\nI've exaggerated [the delay here](https://github.com/TMRh20/RF24/blob/v1.1.6/examples/pingpair_sleepy/pingpair_sleepy.ino#L153) to 5 seconds so I can more clearly see what the current draw is.\r\n\r\nI only see the 5 seconds delay in the serial console, I don't see an extra 8 seconds for the watchdog timeout (I have set the watchdog delay to 8 seconds `setup_watchdog(wdt_8s)`).\r\n\r\n![rf24-issue](https://cloud.githubusercontent.com/assets/1020541/14472221/0c90ff18-00ea-11e6-8616-94ecaf09e6a1.jpg)\r\n\r\n![](http://i.ebayimg.com/00/s/ODAwWDgwMA==/z/qBcAAOSwCQNWdK~x/$_1.JPG) \r\n\r\n![](http://i.ebayimg.com/00/s/NzUwWDc1MA==/z/ANgAAOSwa-dWmuim/$_1.JPG)\r\n"}}
