Using the sleep code does give you a significant improvement. You can connect with a MicroUSB cable (just plug into the jack) and the Feather will regulate the 5V USB down to 3. This allows the Arduino to be easily connected to an AC-to-DC adapter or a battery pack. This project now uses an Arduino Nano, as seen in the schematic below:. The Teensy 3. This is a simplified version of my Solar Panel Battery Charge Controller Using Arduino. The board "is able to run with or without the battery connected," says Arduino, but a battery is recommended to handle peak-power GSM operations. As the design evolved, I let two additional features creep in: Add a temperature sensor to track ambient temperature during the test since that certainly affects battery capacity. The Beetle Ble (Former name as Bluno Beetle) is an Arduino Uno based board with bluetooth 4. Solar Module for Arduino is a small board that can power your Arduino board, to get a totally autonomous outdoor board.
