Full Version: Has anyone considered trying a Framework Laptop motherboard?
You're currently viewing a stripped down version of our content. View the full version with proper formatting.
I know there is a pretty big price difference between an RPi4 at ~$40 and a Framework MB at $350, but you get a full Core i5 and a lot of expandability with USB3/thunderbolt ports.  It is also a bit more modular, allowing you to choose (and later upgrade if desired) how much RAM and M.2 NVMe storage as well as M.2 2230 WiFi modules.  

The motherboards were designed intentionally to run outside the laptop so that when upgrading your laptop the motherboards can continue to be useful.  Framework has even published a set of 3d printable files to house the motherboard in a non-laptop form.  

Additionally the Framework team designed it to be very Linux friendly.  When I can manage it I plan on trying it out. Is this interesting to anyone else?
no i2c or one wire for sensors
"RPi4 at ~$40" not now days.. https://rpilocator.com/
i've used an atomic-pi with some success .
e-sailing did a video on using it on a laptop still no i2c or one wire for sensors.

Personally I'm not sure I'd want a lot of I2C sensors, but that still isn't a big hurdle.

Here is a $20 I2C to USB converter. 


Also USB CAN converter?
if you don't want/need wind, temp, battery, tank levels,ect. you can just use opencpn + usb gps for a plotter on any laptop.

All of those things have commercial NMEA 2000 sensors that can connect to OpenPlotter, via the USB to CAN adapter.  

This short video explains NMEA 2000. I'm not sure why you seem think that OpenPlotter needs sensors connected to it via the RPi GPIO.


Unless there is something else I'm missing.  But I don't think I am.

Maybe not many around here when a Pi4 is plenty fast enough to cope will all that's requires for a boat nav computer at a fraction of the cost and very little power, plus be up and running in no time just by copying a well tested image onto an sd card. I've built from scratch computers for the boat before and the Pi/openplotter is by far the better way to go these days imho.  Cool
