Long time no update, So, I want to show this module, which is integrated between Arduino Pro Mini and Bluetooth HC-05. Two pin header on your right is for the power input from the battery, and another two switches are for turn on the Arduino and Bluetooth separately.
I plan to develop a new PCB module for the same component as shown in the figure below and for extra include accelerometer as well, but all the circuits are designed from the scratch and double layer. No problem, we can send to the China and ask about the development. The most important thing is to design the circuit first.
