  Configuring LED Indicators on Orange Pi Zero 3 There are two indicators on the Orange Pi Zero 3: a red and a green LED. They are quite bright. While the red indicator only blinks occasionally, the green one stays on constantly after Linux boots. This doesn’t suit me, so I decided to find a way how to configure them. The first thing to do is check the available triggers and determine which one is active. This can be done using the following commands (shoulbe be executed as root): # cat /sys/class/leds/red:status/trigger none usb-gadget usb-host kbd-scrolllock kbd-numlock kbd-capslock kbd-kanalock kbd-shiftlock kbd-altgrlock kbd-ctrllock kbd-altlock kbd-shiftllock kbd-shiftrlock kbd-ctrlllock kbd-ctrlrlock usbport disk-activity disk-read disk-write mtd nand-disk [heartbeat] cpu cpu0 cpu1 cpu2 cpu3 activity default-on panic mmc0 mmc1 rfkill-any rfkill-none rfkill0 stmmac-0:01:link stmmac-0:01:1Gbps stmmac-0:01:100Mbps stmmac-0:01:10Mbps rfkill1 bluetooth-power hci0-power rfkill...

I have a small file server that was originally based on an Orange Pi One with an external 2.5" USB-SATA drive. The entire system is powered by an LX-2BUPS module with two 18650. The Orange Pi One only has a 100 Mbps Ethernet connection, which occasionally falls short of my needs. To address this, I decided to upgrade to the latest Orange Pi Zero 3 model, which comes equipped with both Wi-Fi and Gigabit Ethernet. However, after a few hours of operation, I encountered an issue: the external HDD disconnects whenever the OS attempts to read a large amount of data from it. The disk is 100% functional, as it has been running flawlessly with the Orange Pi One for several months. This suggests that the problem lies either with the new Orange Pi Zero 3 or the software. However, the most likely culprit is the power supply. The pinout for the Orange Pi Zero 3 is shown below: Here is my wiring diagram: On the Orange Pi One, power was supplied via a 4.4x1.7 coaxial connector. But the Orange Pi...
