This is a Grove Power module meant for Grove kits such as the Grove Mixer Pack V2. It is the source of power or energy for all the circuits with which it is used. It can plug in a range of power sources such as a 9V battery as shown in the picture, or any battery pack or wall power adapter that supplies power in the range of 5.5V-20V. Grove - DC Jack Power module is based on the TD1410 DC-DC step down converter chip and achieves 2A continuous output current over a wide input supply range with excellent load and line regulation.

• Standard cylindrical DC power connector connects easily to a range of wall power adapters
• Connect 9V DC battery using the connector cable that comes along with the module (as shown in the picture)
• ON/OFF switch eliminates the need for connecting and disconnecting the power source in order to switch the circuit on or off respectively.
• Interfaces to an 'input module' such as an Environmental Monitoring module on one side and an 'output module' such as a User Interface module on another side as indicated on the small illustration on the case
• Uses Standard 4-pin Grove Cables to connect to other Grove modules

Usage

Follow these steps to power up your circuit:

1. The very first thing to do is to build your Grove circuit by connecting input-side and output-side modules to the power module
2. When you are ready to power up your circuit, connect the power module to a DC power source such as a 9V battery using the connector cable provided in the mixer pack, or by using a common wall DC power adapter such as a 5V/1A power adapter used to charge a cell phone
3. Turn the on-board ON/OFF switch to ON position
4. Observe that the on-board green LED lights up when you turn the switch ON
5. Check if your circuit behaves in the way you desired it to work
6. If you need to make any modifications to your circuit, ensure that the power module is switched OFF before you make any changes
