Re: STICKY: Is CM3 compatbile with the CM1 development board?

Just like to throw this out, if this is wrong to do here feel free to delete this post. I recently bought this Dev board on Amazon. I have been using the new Raspberry Pi Compute Module M3+ 8 GB module in it and it works great. I only share this because I think its more handy that the stock one RPI ...

Compute Module M3+ dts file

Where is the default .dts file ?
I thought I would see it here:
https://github.com/raspberrypi/linux/tr ... m/boot/dts

Or am I looking in the wrong spot ?

RPI-COMPUTE3-KIT

Just curious if there might be 2 flavors of the new kit.
I thought it would be nice to also have a baseboard for the CM3x that had the all the same hardware on it as say one of the current RPI boards, such as multiple USB ports, Ethernet connector, and the same I/O header.

Re: WiFI AP with Webserver to configure wifi

I want the device to read some sensor data and put that information to our servers. This is why I need them to set it up for their own WiFi.

WiFI AP with Webserver to configure wifi

I was wondering should I design a headless device to be sold using RPI3 how would I allow the user to set the wi-fi to connect to their own network since they wont have access to the terminal or a monitor. I thought that it would be nice on boot to check a local file to see if the user has set up th...

Why is the installed node so old

I just downloaded Raspbian Jessie, Release date: 2015-11-21. after an update / upgrade I entered in node -v and it said v0.10.29. Yet when I go to the latest stable version, which is v5.3.0 here: https://nodejs.org/en/download/stable/ I have 2 question if some would please answer. #1) Is there some ...

Re: Pi Zero Temp Spec ?

In my experience manufacturers specify operating and storage temp specs for their devices. Take it or leave it. I have never seen a board manufacurer publish a spec that lists all the temp specs of all the components on their board. Often you are lucky to even find out what iz on the board. The ras...

I have googled already before posting. Every one I ran into suggests .conf files that are not on the default image.
How about I change the question a bit. What file stores which is the default audio device at ?

C-Media Electronics, Inc. Audio Adapter

I have a C-Media Electronics, Inc. Audio Adapter plugged into my Pi Zero. In reading other posts about this not working they have said one should modify the file in "/etc/modprobe.d/alsa-base.conf". Yet I do not have this file there. To confirm its working and detected I did: cat /proc/asound/cards ...

Re: Pi Zero Temp Spec ?

Whilst officially it's lower limit is -40 (AFAIK) it may be that some of the high altitude balloon guys or penguin monitor guys may have seen temperatures lower than that in real life. As with anything built in to a product, you'll need to test in an environmental chamber as combinations of compone...

Re: Pi Zero Temp Spec ?

I mean the part with the narrowest range. I.E. -20 to +85 is a narrower range than -40 to +85. But what if one part had -20 to +85 and another had -10 to +120? Then -10 would be the minimum and +85 the maximum. Not determined by the range of a single part. I get what your saying, however I pretty s...

Re: Pi Zero Temp Spec ?

Whilst -40 to +85 is the published temp range, it should be noted that the chip can actually run at MUCH higher temperatures than that. During development the chips are tested in ovens at well over 100 to determine lifetimes and the like. The chip itself, it it detects itself overheating internally...

Just because someone has done something does not mean it should be done or make it right.

They have not been schooled in electronics t...

AFAIK, you cannot buy the 2835 in different temperature ranges - they are all the same. Same fab, same masks etc. Thank you, if this is true then the Zero can ONLY be used for commercial applications. Nothing outdoors. Why not, heck people have flown it to the edge of out atmosphere.
