[What are you using your Orange Pi Zero for?]

2x - PiHole DNS servers

1x - Octoprint 3d Printer server, but I'm going to migrate to an orange pi PC as it has more native usb lcd support.

1x - Portable Wifi to Lan Bridge with MAC address cloning or randomizer

1x - Cups print server. 

[OPi Zero and legacy Armbian - running HOT!]

Raspberry Pi Zero's operating temp range is  0°C to 70°C

The H2/H3 has the same safe operating range.

 

 

My Zero's are running around 50C in an open case with a heatsink on. If I use an enclosed case it jumps to 57C for a high load (webcam server/octoprint)

If you're worried about it add a fan, but it's a safe temperature.

I also recommend connecting to the serial console over UART (http://linux-sunxi.org/File:OPi_Zero_UART.jpg):

 

You can pick up a cable that will work here: http://a.co/78ua1Pa

 

 

Anyone know why I cant get serial out of those three pins?  Is it not enabled by default?   Running Armbian_5.24_Orangepizero_Ubuntu_xenial_3.4.113

Below is my dmesg output.

[OPI Zero boot with SPI]

Does this mean we can use SPI based LCD's? or is that something else
