Block Diagram:

Three type input select:

Mini USB in: 5V, It can get more power .

Battery: 2*AAA, It can support more scene.

Update #1:Add a type input

1、Lithium battery supported. Single cell(3.7V) and Dual Cell(7.4V,Max:9V) all supported.

2、Connector type:ZH1.5

Please note: Due to the board size, I couldn't add the low voltage protection and charging circuit. 

Update #4:Add AAA*2 low voltage one button to boot. 

1、Some  better quality AAA battery still have more energy when the voltage is lower than 1V(AAA*2=2V). How to use AAA battery well, the main is allowing the circuit to boot at  lower voltage and work normally. 

2、Now ,add AAA*2 low voltage one button to boot. When the AAA is 0.75 V(AAA*2 = 1.5V), you can still get voltages such as 5V, 7V, and even 9V(Because of efficiency ,for AAA*2, recommended  not to exceed 10V).

Remar:For test, I use power supply as AAA*2.


Smart structural design. Battery houses are support columns.

Power switch(select) and Adjust :

ADJ: Wide range & Adjustable (Vin-14V).  

ADJ1: Adjustable (1-5V).  

ADJ2: Adjustable (1-5V) .

Output:

2-Way Adjustable(1-5V) output.

1-Way Wide range & Adjustable(Vin-14V) output*.

  *Note: 

1、The wide range output is the source of V_ADJ1, V_ADJ2.Recommend  Adjust the wide range output to V_ADJ1 + 2V or V_ADJ2 + 2V to ensure ADJ1, ADJ2 working properly.

2、When use 2*AAA as power source , The wide range & Adjustable output recommended is Vin-9V(Max).

It also can  provide various power to other electronic devices  by the wiring.

Update #5: Add 2 Pins(GND) on the TOP side , It is more easy that connect to other electronic devices  by the wiring . 

Multi way voltage display

4-way:Vin_Mini USB & Battery 2*AAA、V_ADJ、V_ADJ1、V_ADJ2.

Green digital display, clear and accurate.

 Update #6:Add a Jumper for voltage display

Output Brief Test Data:

 **Note:  

This output current is only when using power supply ,Not actual battery. Due to the limit of battery quality and capacity,the battery current is less than this current. For the current and discharge cycle when using battery, please refer to the test data in the following table.

Standard Accessories:

Breadboard X 1PCS;

Mini USB Line X 1PCS(2A);  

Jumper X 10PCS (Color Random);  

Adjust Screwdriver X 1PCS.

Update #2:Add a ZH1.5 line as Standard Accessories:

ZH1.5 line,L=10cm,2 Head X 1PCS

Risks and challenges

During design phase, I tried different structure and different solution for building the circuit. The risk is on the power ability assurance. How to get the wide range output and make sure the power converting efficient is hard to ensure. But finally, I did my best to make it working well.
