If you’re looking for a useful tool for long-lasting Raspberry Pi, such as longer battery life or automatic power on / off, this HAT power management is the perfect choice.
This HAT can significantly increase battery life by automatically starting the device for a certain time and automatically switching it off at another time. It can be configured to monitor the Raspberry Pi voltage / current status in real time and turn off the Pi according to the operating status. In addition, the kit includes a convenient power switch for easy on / off (soft shutdown of Pi by software), preventing data loss due to power disconnection.

Industrial use of Raspberry Pi Compute Module 3+
With Compute Module 3+ options from Raspberry Pi, TECHBASE upgraded their ModBerry 500/9500 industrial computers. From now on the ModBerry 500/9500 can be supported with extended eMMC, up to 32GB. Higher memory volume brings new features available for ModBerry series. One of the options is SuperCap power support.
Higher performance of ModBerry 500/9500 with extended eMMC flash memory, up to 32GB , powered by quad-core Cortex A53 processor allows the device to smoothly run Windows 10 IoT Core system, opening up many possibilities for data management, remote control and visualisation.
