Soft Power Switch Mk2 - JST 2mm - power switch - SparkFun PRT-26993
The SparkFun Soft Power Switch Mk2 is a passive On/Off power switch that allows you to power up and safely shut down your system with short presses of the button. While a long press of the button will force the power off. The Mk2 version supports voltages from 1.8V to 5.5V and is designed for use with single Li-Po cells with a built-in 2-pin JST connector, so the typical nominal voltage will be 3.7V. The product has a built-in 2A self-resetting fuse, LED indicators, and the ability to connect a larger external button.

Soft Power Switch Mk2.
Features of Soft Power Switch Mk2
- Compatible with Arduino - the module allows you to create projects with the Arduino minicomputer
- Built-in momentary button - holding the button for 10 seconds forces the power to be cut off
- It operates from 1.8V to 5.5V - the minimum input voltage is 1.8V and the maximum is 5.5V . The board is designed for use with single Li-Pol cells with a built-in 2-pin JST connector, so a typical nominal voltage will be 3.7V
Note! The module is not designed to work with AC loads - it only supports DC loads up to 5.5 V.
Module pins
The module has two 2 mm JST connectors on the board, as well as solder pads with the following leads:
- VIN - Voltage input (from 1.8 V to 5.5 V). The voltage is supplied to this pin from a single Li-Pol battery, which is nominally about 3.7 V
- VOUT - the output voltage of the board when the switch is active
- GND - grounding
- BTN - (button) possibility of connecting an external button
- PUSH - open-drain output. The pin requires a pull-up resistor. A low state indicates that the button is pressed
- OFF - forces shutdown (high state must be given to disconnect power)
- VIN - The VIN LED connects to the input voltage. It indicates that there is voltage on VIN. The LED can be turned off using the LED jumper on the back of the board and under the silkscreen marked IN
- VOUT - VOUT LED connects to the output voltage. Indicates that there is voltage on VOUT. The LED can be turned off using the LED jumper on the back of the board and under the screen marked OUT
- LED (below IN) - By default the LED is closed. This connects the VIN LED to the input voltage. Cutting it will turn off the LED for the input voltage
- LED (below OUT) - By default the LED is closed. This connects the LED to the output voltage. Cutting this jumper will turn off the LED for the output voltage
