Hi! First off I love this community section- I’ve solved a lot of issues just by reading around here so thank you!
I am trying to build a stand alone mesh network with an Argon and a few Xenons so I bought 9v rechargeable batteries to power each device individually. I didn’t realize until after I got them that the voltage of these batteries are way too high to safely power the devices. I am new to this circuitry world and don’t know what I should use to drop the voltage from the batteries to something acceptable and safe for the devices so I don’t fry them.
Can anyone provide any guidance on this? I would like to fix my mistake instead of just buying LiPo batteries.
Thank you in advance!
Edit: Found that a buck/step down/DCDC converter will do the trick. Not sure what the difference between those are.
