1. i o These pins can work as interrupt inputs example to have some light indicators we COM USART Serial Port will need the LED component These JST female headers include 3 pins each The middle pin is the signal which is connected directly to the relative pin on FEZ board as marked on the header f N DY b ia Fy r ea Copyright 2010 GHI Electronics LLC www tinyclr com TFT Display Expansion Provides the ability to connect TFT displays to FEZ Cobra and do color graphics Made to work with both the 3 5 and 4 3 displays Both displays have touch screens This expansion is sold separately s JEJ ar i eal ox a wn Mt A GAE An optional enclosure for your project with FEZ Cobra This optional plastic enclosure is custom made for FEZ Cobra The opening on one side exposes all the connectors and the opening on top side is ready for the TFT display The other side of the enclosure is made for the user to add any additional components USB Host Connector USB host allows FEZ Cobra to access most USB devices Reading a mouse keyboard or joystick How about reading and writing files on your thumb drive Or controlling your printer No problem FEZ Domino can do it SaDisk ZW SD card Connector Developers can read write files on SD cards directly with FEZ Domino with an on board SD socket and FAT file system library 2 0c gt Copyright 2010 GHI Electronic2. EZ cobra Board i G etecironics FEZ Cobra is based on the EMX Module providing a more robust foundation The benefits include 16 MB of RAM 4 5 MB of flash memory Ethernet and graphics support Build your next project in minutes by connecting FEZ Cobra to one of the many shields or components Many libraries are included such as FAT file system threading UART SPI I2C GPIO PWM ADC DAC and more Powering FEZ Cobra The easiest way to power FEZ Cobra is through the USB cable In case the board is powered through USB the voltage on the 5V pins will be sourced directly from the PC USB 5 volts which is in most cases less than 5volts 4 5 to 5 volts Optionally the power connector can be used as well Using either power source will efficiently supply power to the 3 3V and 5V pins The regulators on cobra are capable of high voltages over 12V but since FEZ Cobra draws a lot of power the regulators will heat up especially when the TFT display is connected Overheating will damage the regulators enohehene J 4 S a ac a ja a a a a o m a ni work RLT tt e D L 2 6 OER So this is what you should know when using external power source 1 Ifyou are not connecting any display then you can get away with up to 9V We still recommend 6V You do not need regulated 6V so any transformer should work 2 Ifyou are connecting a TFT display then definitely 6V only You
