stronger Raspberry Pi 3 Alternatives

I haven’t done any benchmarking as of yet. Once I do, I’ll post the results.

If you could do some comparisons using nmon between a Pi3 and the Rock64 I’d really be interested in the results, as they pertain to this topic.

Otherwise, I’m looking forward to your results on the Rock64.

As i understood, u were able to use GPIO commands the same way u do on a raspberry. Seems to be a nice option

@Mykle1 The b/g/n adapter is a further $7, and will also give you an antenna for better connectivity. The more robust (and likely excessive) b/g/n/ac dual-antenna is $22.

Has anyone tried running MM on an Intel Compute Stick? I’m not normally a fan, but it seems it would suit the form factor and be easily placed behind a mirror, and has more fulsome specs to accommodate advanced modules, media streaming, etc.

No, but I’ve used, and am using, old laptop boards (and one netbook) with ubuntu. They can be gotten on the cheap and come with everything you need. :-)

Well, i need to say that especially for me, the ability to use GPIOs is important. Unfortunately the power of the raspi’s & co is not as good as x86 systems.

Does anyone know if it would be possible to use MagicMirror on a x86 system and uses external GPIOs? I installed an MM instance on a virtual machine running Linux. When i add a module which uses GPIOs i get errors. Is there a possibility (maybe with server-client)

You mean something like this:

I just did a google for “USB GPIO breakout board”

do you think its just that simple? that would be great.
The question is, if the program code or the configuration will be the same as on a RPi. Or are u need to do some complicated hacks to use the board with MM?

edit:
okay… i searched now, too.

Found this:

what do u guys think about that?

Well, adafruit has python sample code. You likely need the node FT232H module to use it from JS.

https://www.npmjs.com/package/FT232H

Does it actually work - I have no idea - that board is also apparently out of stock :-)

Sample python code below

# Import standard Python time library.
import time

# Import GPIO and FT232H modules.
import Adafruit_GPIO as GPIO
import Adafruit_GPIO.FT232H as FT232H

# Temporarily disable the built-in FTDI serial driver on Mac & Linux platforms.
FT232H.use_FT232H()

# Create an FT232H object that grabs the first available FT232H device found.
ft232h = FT232H.FT232H()

# Configure digital inputs and outputs using the setup function.
# Note that pin numbers 0 to 15 map to pins D0 to D7 then C0 to C7 on the board.
ft232h.setup(7, GPIO.IN)   # Make pin D7 a digital input.
ft232h.setup(8, GPIO.OUT)  # Make pin C0 a digital output.

# Loop turning the LED on and off and reading the input state.
print 'Press Ctrl-C to quit.'
while True:
	# Set pin C0 to a high level so the LED turns on.
	ft232h.output(8, GPIO.HIGH)
	# Sleep for 1 second.
	time.sleep(1)
	# Set pin C0 to a low level so the LED turns off.
	ft232h.output(8, GPIO.LOW)
	# Sleep for 1 second.
	time.sleep(1)
	# Read the input on pin D7 and print out if it's high or low.
	level = ft232h.input(7)
	if level == GPIO.LOW:
		print 'Pin D7 is LOW!'
	else:
		print 'Pin D7 is HIGH!'
