There are plenty of devices you can buy that provide a USB interface which you can utilize. For instance: http://nimbelink.com/skywire-cellular-modem/ http://www.multitech.com/brands/socketmodem-cell Please keep in mind that most 4G LTE modems like this are still fairly expensive. You can maybe find...

Just finished soldering mine and I'm happy to report it's working :mrgreen: https://pbs.twimg.com/media/C9cmry7XgAANQqB.jpg:large Which part did you end up going with? I long ago gave up trying to find a decent source for cheap, low quantity vertical SODIMM connectors outside of China. The horizont...

That will be very helpful. I kind of like the idea of the CM3 Lite having the option for adding your own eMMC. Say, what? I've never heard of a way to add your own eMMC to a CM3. There are two versions of the CM3. The CM3 and the CM3L (or CM3LT). The former has 4GB eMMC on it. The later has none an...

Well if nothing else at least we get to peruse the datasheet. Maybe someone already posted it, but its the first I'm seeing of it. Ahem - https://www.raspberrypi.org/documentation/hardware/computemodule/datasheet.md put up in October (https://www.raspberrypi.org/forums/viewtopic.php?f=98&t=162690) ...

I think Nintendo just saw one of the various Raspberry Pi powered 3D printed mini-Nintendos and thought "Wait a minute....we should make that!"

I'm hoping I can grab a dozen before anything happens. I would love something like this to stick on my own boards and not have to deal with the SODIMM connector and the Pi CM. Don't get me wrong, I love the Pi CM, and I'm really hoping the CM3 will actually come out soon, but this form factor is nic...

Hi, the XTAL I use is a ceramic SMD type: http://www.reichelt.de/Crystals-SMD-Ceramic-Case/25-000000-MJ/3/index.html?ACTION=3&GROUPID=4003&ARTICLE=85011&OFFSET=500&LANGUAGE=EN That one seems to be out of specs a little bit (only drives 100uW), but works fine on several boards. If you soldered the c...

Hi, I also did it with the reference schematic for the LAN9514 and it works without any problems. The difference I can see between your schematic and the reference is, that you did not connect the JTAG-Pins except TDO to VDD and on of the Test-Pins is not connected. Atached is my schematic I use. D...

There is a problem using the "sdhost" driver on the CM - I haven't got to the bottom of it yet, which is why current kernel configs now use the older "mmc" driver on CM. However, the most recent Raspbian releases were made the day before that commit, so the default is still currently "sdhost". I wo...

I recall back when Pis were new (so new they weren't really available) that a batch had to go back to the factory because the wrong kind of RJ-45 jack was installed. Something about built-in "magnetics". The J3011 ethernet jack I am using has built-in magnetics. Same as the one the LAN9514i referen...

I recently built a custom Pi CM board, and everything seems to be working OK except for the ethernet jack. I am utilizing a LAN9514 IC to split the CM's USB line into an ethernet port and 4 USB ports. I have an eth0 interface available, but the Ethernet port's LEDs do not light up when a cable is pl...

So I decided to use the latest nightly build of Raspbian Wheezy NoX. Works perfectly.

I'll give Jessie Lite another try in a few months.

MH6

So I recently installed the 2016-03-18 version of Jessie Lite on my CM, and have since been having trouble booting. It will sometimes work, and sometimes not work, and I'm not sure what the cause is. I've added "dtoverlay=mmc" to my cmdline.txt to see if that helped fix the problem, but it did not. ...

Have any screenshots of it?

Here is a picture of my current prototype. The modem works perfectly when the green USB cable is connected to a non-powered hub instead of directly to the Pi. If connected directly to the Pi, it only works if I force USB 1.1 mode.

If you have a RPi B+ or later, you could increase the USB BUS from 600ma to 1200ma if you have a decent 5V2A PSU https://projects.drogon.net/testing-setting-the-usb-current-limiter-on-the-raspberry-pi-b Sorry, forgot to mention I've already added max_usb_current=1 to my /boot/config.txt I was hopef...

I have a 4G LTE modem that connects to my Raspberry Pi 2 B+ via USB. When directly connected to the Pi, the device does not show up, and I get repeated messages like this in dmesg [ 42.045357] usb 1-1.4: new high-speed USB device number 17 using dwc_otg [ 42.305364] usb 1-1.4: new full-speed USB dev...
