Very cheap but works perfectly. No config.txt changes was needed at all. I've booted<br />

Raspbian and OpenELEC. Monitor is detected correctly and the optimal resolution is set<br />

(Raspbian) or you can change the res in the menu (OpenELEC). The /opt/vc/bin/tvservice<br />

is able to read monitor edid data. I tested the adapter using NEC 72VM 15" LCD.<br />

(1280x1024 60Hz, 1024x768 60Hz, 640x480 works) The adapter is based on Lontium<br />

LT8511A chip, but I was unable to get the spec for it. The D1 diode is getting very hot<br />

though. Most likely the adapter drives more than 200mA. The standard RS Components<br />

1,2A usb power supply is able to provide enough power for the <strong>RPi</strong> and the adapter. I'll<br />

try to modify the adapter to connect external power to bypass D1. Marcin.<br />

DVI-D -> VGA active adapters<br />

None are currently listed<br />

Composite->SCART<br />

SCART adapters (SCART plugs with three RCA connectors in the back), will probably<br />

work when used with the yellow RCA plug connected to the R-PI's RCA video output.<br />

Additionally using a splitter cable (3.5mm jack plug on one end, and red-white RCA<br />

plugs on the other end) will probably work when plugged into the red and white (left and<br />

right audio channels) of the SCART adapter.<br />

▪ Generic - works<br />

Composite->VGA converter boxes<br />

▪ Extron DVS-204 (http://www.extron.com/product/product.aspx?id=dvs204%7C) -<br />

works no problem!<br />

<strong>SD</strong> cards<br />

The <strong>SD</strong> card is a key part of the Raspberry Pi; it provides the initial storage for the<br />

Operating System and files. Storage can be extended through many types of USB<br />

connected peripherals.<br />

When the Raspberry Pi is 'switched on', i.e. connected to a power supply, a special piece<br />

of code called the bootloader is executed, which reads more special code from the <strong>SD</strong><br />

<strong>Card</strong> that is used to start up the Raspberry Pi. If there is no <strong>SD</strong> <strong>Card</strong> inserted, it will not<br />

start. Do NOT push in or pull out an <strong>SD</strong> <strong>Card</strong> while the Raspberry Pi is connected to the<br />

power, as this is likely to corrupt the <strong>SD</strong> <strong>Card</strong> data (you might get away with it, but it is<br />

best not to).
