Insert the SD Card into the Raspberry Pi and supply it with an internet connection using an Ethernet cable connected to your router.Using your laptop, download the Arch Linux image from here: and write it to an SD Card using Win32DiskImager (if using Windows) or dd (if using Linux).Internet connection for the Raspberry Pi over Ethernet.A Windows or Linux PC with an SD Card reader.A powered USB Hub (Raspberry Pi by itself will not be able to supply enough current to the modem).5V DC power supply capable of supplying current greater than 1.0 Ampere.For the conversion you could use the car accessory for charging phones or build one yourself using LM2576.Īs for the K3770-Z, here is how I got it to work on Arch Linux. The second problem can be solved simply by using a 12V 2.2Ah Sealed Lead Acid Battery and a 12V to 5V DC-DC converter. The charger can supply only 600mA 5V where as the 3G modem definitely requires a lot more during registration. When I finally did get the modem to work on RPi, I found that the iBall Portable Charger ( Datasheet here) could not source the peak current requirements of the modem when it turns on registers to the 3G network.Since this K3770-Z 3G USB Modem from Vodafone worked on Ubuntu 12.10 x86 without requiring any installation or configuration, I was sure that I could somehow get it to work on Raspberry Pi

I couldn't immediately figure out how to get K3770-Z to work on Raspberry Pi.
