Battery Module

Product detailed description
The Battery Module is designed as a power supply source for the battery-operated units. The integrated low-power buck converter provides excellent efficiency from the four AAA 1.5 V Alkaline cells. It also features an extra 5-pin socket where you can connect any TOWER tag.
The load disconnect circuit can disconnect the batteries if any other power supply source is connected to the system (e.g. AC adapter or USB cable). The battery voltage can be measured on one of the analog inputs of the standardized header (P0/A0/TXD0).
If the four AAA batteries are not suitable for your application, you can use the external voltage input, which can handle up to 10 V. You can find the external input on the two pins in the middle. These pins are compatible with the popular JST connector used for Lithium batteries.
Another useful feature is a prototyping area for soldering your own circuits.
