Raspberry Pi Power Management HAT Adds RTC, Battery Management, Software On/Off
If your Raspberry Pi project runs on battery, but may not need to be turned on 24/7 in order to lower power consumption, you’d have to find a way to schedule on and off times, and power off the board cleanly either when the battery is almost depleted, or your timer requires it
There’s no built-in support for this in any of the Raspberry Pi boards, but Waveshare Power Management HAT can help you do just that since it adds an RTC, and enables software-controlled power timers and battery monitoring via an Arduino compatible ATmega328 MCU.
ROCK Pi SATA HAT Targets ROCK Pi 4 & Raspberry Pi 4 NAS
Raxda ROCK Pi 4 is a single board computer (SBC) powered by Rockchip RK3399 hexa-core processor and inspired by Raspberry Pi 3 Model B+.
The company has now designed ROCK Pi SATA HAT expansion board to design 4-bay NAS based on Raspberry Pi 4 and ROCK Pi 4.
There are 3 models with support for 2, 4 or 5 drives:

There are 3 models with support for 2, 4 or 5 drives:
- Dual/Quad SATA HAT connected over two USB 3.0 ports and working with both boards
- Penta SATA HAT connected over PCIe and compatible with ROCK Pi 4 only
