The POWERplate is a multipurpose power management solution for your Pi-Plate stack that provides a combination of must-have features for the Raspberry Pi that includes:

four different input connectors that allow you to use the power supply of your choice.
an RPi compatible, battery backed, Real Time Clock
a 45mm cooling fan
a power switch with bicolor status LED
a low power microcontroller to handle scheduled tasks
5VDC power output connectors to drive additional peripherals in your system
Included with the POWERplate is a set of heatsinks for the hot components on your RPi and the backup battery for the RTC

Data shows that the combination of chip mounted heatsinks and a fan provide the best cooling performance for the quad core CPU on the Raspberry Pi4:

Unlike our other products, only a single POWERplate is required for your Pi-Plate stack and it should be placed directly above the the Raspberry Pi for maximum cooling. Also we are using plugable terminal blocks to eliminate the hassle of having to disassemble a stack of plates to add or remove cables. See below for detailed features for the POWERplate.

Power Management

Provides four different connectors for 5VDC input:
- USB-C
- USB microB
- 5.5mm barrel
- 5mm pluggable terminal block
Five "always on" 3.5mm pluggable terminal blocks to provide 5VDC for your setup
Onboard A/D converter allows monitoring of both input voltage and current
Smart customizable power switch
Power up scheduler for remote battery operated applications
Software shutdown
Bicolor LED provides programmable power status at a glance

Cooling

Onboard 45mm fan cools RPi
Each POWERplate includes a set of heat sinks for the hot components on the RPi
Fan can be controlled manually for custom cooling solutions or to minimize quiescent power consumption for battery based power solutions.
