GeeekPi Raspberry Pi DockerPi Power Board: Versatile Power Supply with Auto Cooling Fan, Safe Shutdown & Expansion Support for Raspberry Pi 4 Model B, 3B+, 2B/3B Review

I have this board on my Pi3B+. The board is poorly documented which GPIO pins are needed for monitoring when the board is in shutdown mode. Shutdown mode can only be initiated with a button on the circuit board or the remote control. You can't shut down from the command line or the GUI and expect the Pi to shut down. My particular board requires two button presses to turn on, this is also undocumented. It doesn't matter whether I use the remote control or the button on the board. Sometimes it…

Pros: - Max voltage is high enough, you can run on 4S LiPo battery - Fan can cool Pi 4 if you use flat heatsink have disadvantages: drivers have closed code

I am using Docker 4 I2C relay boards and this power board does a great job of powering the Pi and 3 Docker 4 relay boards in unexpected situations when the Pi is in the control box is hidden.

I have bought four of these since December 8th. I installed them on Raspberry Pi 3B+ and 4s. One was delivered to DOA, one died 2/4/2020 and the other died 2/21/2020. Two of the dead were on daily duty. The one remaining block is used by an elementary school student and is not used on a daily basis. Let's see how long this lasts. I would say if you are looking for a reliable power supply and fan, you should go for RPI power supplies and a case with a fan. These are just not reliable.

Used to power/control the 3D printer server and enclosure. It controls my lights (12v), fans (12v) and relays (5v) with 12v 3a input. Also cools my rpi 3b+. Although it is a premium price, it has a voltage difference and offers enough power for small one-off applications. Please note that it still supplies 12V when plugged in and unplugged, only the gpio pins are behind the power button. The power button "works" without drivers, but it is considered a hard shutdown if only used to turn off your
