Note: If you leave the Grove Connector unconnected, Version Two behaves exactly like Version One.
The USB PowerControl board is a USB to USB solid state relay. It is is a digitally controlled power switch for your Arduino or Raspberry Pi. It is a Pi On and Off switch.
We have now added a Grove Digital Input that allows you to control the USB PowerControlV2 using two GPIO Lines (one enable and one control line) to switch on and off from a Grove Digital Port. The Grove Enable Line, when high, disables the LIPOBATIN line and makes control of the device under the Grove Control Line. When the Grove Enable Line is low, the LIPOBATIN line controls the relay as in the original USB PowerControl. The Grove Enable Line is pulled down by a 43K resistor so if it is disconnected, the USB PowerControlV2 is compatible with the original USB PowerControl.
Grove GPIO Control Circuitry for the USB PowerControl
This circuitry is provided to allow the USB PowerControlV2 to be controlled by either LIPOBATIN or the state of the CONTROL Line (J3 Pin 1). ENABLE (J3 Pin 2) controls whether the USB POWERCONTROLV2 is switched by LIPOBATIN or the CONTROL line. Remember that LIPOBATIN is not a digital input. It is designed to look at the voltage level of the battery.
The truth table for the USB PowerControlNE V2 is given below:
Features
- Can Switch the Power to any plugged into the Female A USB port
- On/Off Controlled by a single control line Implements Hysteresis on Control line
- 3.8V/3.3V Turn On/Off Voltage with LIPOBATIN
- Grove Digital Connector - ENABLE and CONTROL your USB Port
- Over Current Protection
- Thermal Shutdown
- Reverse Current Blocking
- Can be connected to GPIO Pin or directly to LiPo Battery
- Supports both Arduino and Raspberry Pi
- Has Dual USB ports - no more cutting USB cables
- Will work with SunAir and SunAirPlus Solar Power Controllers
Application Note Published *Secrets of the USB PowerControl!*
- Making the USB PowerControl on by Default, when connected to a GPIO that needs to be initialized (like the Pi and Arduino GPIOs)
- Turning off the USB PowerControl even if the battery is higher than ~3.3V and lower than ~3.8V.
- Controlling the USB PowerControl with a 3.3V GPIO Line, WITHOUT a buffer.
