Hey there, I've been facing some problems with choosing power source for my wearable design. I donot have much components on the board, have microcontroller, an ADXL335 accelerometer, some passive components like resistors, capacitors etc.,
I am in a dilemma whether to use a coin cell or a button cell or a Li-Po battery to power up my board. I am thinking of using a Li-Po but many are suggesting to use coin cells. What matters how we power up board? Is it the current rating that matters?
