I'm planning the using the bq27510-G2 to monitor a inbuilt battery in my portable system which is part of my HNC electronics project. The system uses a single 3.7V 1000mAh LI-ion battery, the battery is charged by the bq24072 via the mini-USB port and a 3.3V LDO regulator to lower the 3.7V battery voltage to the 3.3V system voltage.
The overall project is to build a Bluetooth handsfree/headphones from which I will need to prototype the system on multiple module one-sided PCB's board to make fault finding and rework easier than moving to a 4 layer PCB board for the finished circuit.
This is where my questions come in:
- Is it necessary to purchase the bq27510EVM or can I make a very similar single layer module that is attached to the prototype system, and just buy the EV2300/2400 for setup etc ?
- If so when I incorporate the bq27510-G2 into the multilayer PCB system would I just need a I2C connection to flash the battery data to the bq27510.
- What is the average time taken to create the Golden Image?
Sorry to ask these beginners question but I don't want to waste time and even £££ buying the wrong tools or IC's.
Hope you can answer my questions and please anyone point me in the right direction. ^^
Here is a very basic layout of the power system which I'm thinking of using:
