Hello!
In the deep sleep modes, would using the internal RC instead of an external 32kHz XTAL consume more power?
Also, is there a way to measure power consumption with the basic dev kit? I thought of desoldering FB1 and measuring on
these 2 points, but am open to suggestions and ideas!

Hi irfansehic,
There is no simple answer on this it depends on the XTAL that you are using and the power consumption of each XTAL, in general the RCX will consume a bit more but there are cases when the RCX consumes less than the RCX (that depends on the connection interval, bigger period less times of performing the calibration procedure). Either way you wont see significant difference between choosing as LP clock the RCX or the XTAL as far as i am aware. Regarding the power measurements you can check the Tutorial 5 : configuring sleep mode on DA1458x at the tutorial section on the support site, the equivalent header for the basic kit is the J5.
