Hello everyone,
I'm struggling with a project because of the space allocable to electronics.
I can't use a classic 9v battery because it don't fit inside so i was thinking about use coin batteries but it still a little too big so i think i can use a 23A/A23 (8lr932) but i read that it could burn the rest of the electronics, so is there any way to solve that problem ? maybe with adding a regulator or with an other type of battery i still don't know about ?
Thanks for your help
What is a 'classic 9V battery'?
What voltage do you need?
What current draw do you expect?
How much space do you have?
Have you considered an external battery holder?
I mean a 6LR61
I just want to put an arduino nano, a speaker, a switch and some leds inside a 3d printed han solo blaster (dl44), the space inside is approximately 351655mm for the arduino, the batterie and the speaker, the rest can fit in others parts.
And i can't have an external battery.
Such small battery will contain only small amount of energy and may have problems providing enough power.
I would try to find a small Li-pol battery.
I kwon but i don't need a lot of durability, and lipo are too big too.
Try changing to a ProMini, it is smaller and thinner being single sided and not having the USB connector. All the same IO as the Nano.
Connect and FTDI Basic to program it, then remove when your development/testing is done and you are ready for install.
This battery is 35 x 24 x 5.2mm thick.
That should fit in your 35 x 55 x 16mm space.
Or 100 mAh, even smaller.
Thank you, but is that 3.7V enough to power it ?
