TinyDuino Processors & TinyShields / Consistent 5V - external power
« on: August 08, 2017, 06:51:10 AM »
Many threads in this forum show how the 3.3V-4.2V tiny batteries are not powerful enough to run many stacked boards on battery supply.
I have similar experiences. The code works fine on USB souce with 5V but when I switch to the tiny 290mAh 3.7v battery the green light just barely runs and wireless transmission etc breaks down etc.
So here is my question, how can we get a more consistent 5V / 500mA (or whatever is required) power supply to the tinydinos?
The tinydino processor board description states the following:
>>External power supported with a 0.1″ power connection holes. Supports automatic switching between +5V USB and vbatt
One option is to solder a external power supply to the processor board - can someone explain me in simple terms how to do this or point me to a tutorial please? E.g. how would I solder a powerboost 500c board to the tinydino processor board?

Thanks for any help
