Thank you for the information I will look into when i arrive at my new home.
I guess you got the answer, but here according to tech specs:
● input: 7.5 - 12.0 VDC or USB powered
● output: 5 VDC and 3.3 VDC regulated
● analog reference: 2.6 - 3.3 VDC
only required when using ADC features
● max current: 8 mA per pin
digital pins 2, 3, 7: 16 mA per pin
analog pins 0-3: 2 mA per pin
microcontroller max current: 200 mA total
● digital i/o are 3.3 V--but 5 V tolerant
