Sorry in advance for my question, I am new at this.
I would like to use the AEM10941 e-peas based supercapacitor charger from https://www.tindie.com/products/jaspersikken/solar-harvesting-into-supercapacitors/ to solar power a GPS tracker (Ublox SAM-M8Q) using a ATmega328P. My plan is to get a GPS fix + transmitt using LoraWan and repeat every time the 3.3v regulated output that are enabled when the two * 10F 2.7V AVX has sufficient charge 4.5v.
As far as I understand two 10F 2.7V AVX should be able to power this setup when a ublox gps coldstart draws 45mA for 28s, the ATmega328P 13mA at 3.3v/8Mhz and a few mA for LoraWan transmition. The AEM10941 charges the supercapacitors up to 4.5V and the outputs are enabled down to 3.6V. So if my tracker uses 80 mA the 2x10F*(4.5V-3.6V)/0.08A= 225s giving my plenty of time to run my sketch. Could it be sufficient with one 10F 2.7V AVX supercapasitor?
Am I missing something here or am I just way off?
