Battery shield for Arduino raspberry pi esp-32 esp8266 with Switching Booster circuit is a portable mobile power supply. This is a battery shield for all kinds of MCU that operate at 5V or 3.3V it can make a regulated fixed 5v and 3.3V DC voltage to run the development board easily
Special attention: the installation of the battery must be determined positive and negative, the board has been clearly marked positive and negative! Installation errors will burn out the module!
Output interface: 2.5mm header and standard USB socket
5V output current: 1.3A max; 3V output current: 1.0A max
Charging indicator: red light during charging, full green light
Note:
Batteries are not included, please buy them separately.
You can easily install the shield on your Arduino Uno and use your other shields too
The shield has a tiny switching power supply that can make fixed regulated 5V DC and 3.3V DC even if the batteries voltage drops down
The shield works with 2 16340 size batteries and has an ON/OFF switch
The mobile power is stacked on the Arduino board and powered via the 5V/GND pin. We also provide a USB-A output interface that you can use to connect to other devices using a USB cable. The charging interface is micro USB, and the charging tool is very convenient to obtain (such as: for Android mobile phone adapter). When it is stopped, it is recommended to turn off the power output and let the mobile power supply enter the standby state, thus saving limited battery energy.
