Beyond the Arduino 8
Posted: Sat Feb 06, 2016 3:45 am
I am using a basic breadboad setup (not using a Toadstool). Here are my power reduction results:
Experiment 0: 0.024 Ampere (baseline reading at 5V supply)
Experiment 1: 0.023 Ampere (PPR register set)
Experiment 2: 0.015 Ampere (sleep mode activated)
Experiment 3: 0.015 Ampere (BOD sensor disabled)
Experiment 4: 0.004 Ampere (3.3V supply)
A quite significant power reduction of 89% (from 120 mW down to 13.2 mW)!
Note: the batch of µCs that I bought turned out to be ATMega328 instead of ATMega328P, which explains why there is no change when disabling the BOD sensor (since the ATMega328 does not have a BOD sensor, according to the Atmel Datasheet).
Thanks for this series, much appreciated.
