TPL5110 Nano Power Timer Hookup Guide
Elias The Sparkiest Hardware Hookup
We're going to power a RedBoard Turbo with a 3.7V LiPo Battery and set it to a 14 second delay. By default, the board comes with every switch flipped to the ON position which is 3 second timer. To set the timer to 14 seconds, we'll turn some switches to the ON position and others to the OFF position. I used tweezers because the switches were too small for my hands.
To get a 14 second delay switches 'A' + 'D' + 'E' must be flipped ON, and the other swtiches flipped OFF. Next solder a 6 pin header of your choice to the Nano Power Timer. After the six pin header is soldered to the Nano Power Timer, plug in three wires into the female header as follows:
We'll use a Schottky diode to protect the TPL5110 when the RedBoard Turbo is connected to a computer when prototyping and uploading code. Additionally, we'll add a pull-down resistor on the Done pin. Depending on your microcontroller, you may not need resistor. After wiring your circuit together, you may have something similar to the image below without the battery connected.
Let's move onto the code.
