FEZ Panda II and Arduino Comparison
FEZ Panda II is not an Arduino board, but it makes use of the
idea of having a stackable hardware platform. The similar form
factor between FEZ Panda II and Arduino allows developers to
use almost any of the available Arduino shields.
While using the same shields, FEZ Panda II offers more powerful
hardware and software platform, greater flexibility and far more
features. Starting with Microsoft Visual C# Express and the
possibility for debugging and ending with high-end libraries like
USB device, threading, XML, better Ethernet networking and
many others.
Additionally FEZ Panda has extra IOs exposed on an easily
accessible 40-pin female header.
Expandability of FEZ Panda II
Boards that install directly on top of FEZ Panda II are called shields. The most
common shield for FEZ Panda II is
FEZ Connect shield
which provides an
Ethernet connection plus exposes sockets compatible with the main 3-pin e-
blocks GHI offers.
FEZ Touch
is also another way to expand FEZ Panda II. It is a 240x320 full 16-
bit color display with touch screen.
Powering FEZ Panda II
The easiest way to power FEZ Panda II is through the USB cable. Optionally, the power connector can be used
as well. Using either power source will efficiently supply power to the 3.3V and 5V pins (exposed for shields).
The 5V shield pin is a special case, it can be used to power the shields and FEZ Panda as well.
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).
