Hi,
I'm making a wristwatch with my teensy, I'm designing a custom PCB and everything.
I'm planning to supply power to my watch with two aaa batteries. each battery has a 100mah capacity with a voltage of 1.5v.
If I connect the two batteries in parallel, I will get a 3V input and 1000mah capacity.
If I connect them in series, I will get a 1.5V input and 2000mah capacity.
Is it possible to drive the teensy with a 1.5v or 3v supply? or does it have to be above 3.3v?
Also, I don't know how to calculate my watch's power consumption. It has a teensy 3.2, an i2c 128x32 oled, 5 leds, and 1 neopixel.
Thanks for everything!
