Hello everyone,
I am designing wearable device that can tracking GPS and send coordinator of user to server using GPRS and may call/sms when user need it
My question is how to design power for this device?
I use Quectel module that have 2 part is GSM part and GNSS part:
- My battery: 540mAh
- GSM part need 3.3V to 4.6V and about 500mA
- GNSS part need 3.3V and 40mA (at peak current)
I see reference of Quectel, they suggest to use LDO to supply for GNSS.
Do you have any suggestion for me?
Thank you
