How to use the module
T e following section describes ow to use t is module.
Components/Tools required
Along wit t e module, you may need t e items in t e list below for easy and fast installation.
1. USB A to Mini B cable.
2. Medium size P ilips screw driver.
Connection Details
IMPO TANT Please exercise utmost caution while working with electrical mains or other
high voltages. Failure to comply with safety regulations may result in injury and or death.
Connection Diagram
Above image s ows basic connection diagram t at can be used in most of t e situations. Use a USB A
to Mini B cable for connection to PC. T e following sections identify individual connections in detail.

USB Interface
T e on board full speed USB controller elps a PC/Linux computer to communicate and
control t is module seamlessly. Use a USB A to Mini B cable to connect wit a PC. By
default, t e logic section of t e module is powered from USB so make sure not to
overcrowd unpowered USB ubs(t e picture on t e rig t s ows USB Mini B connector).
Visit ttp://numato.com/cables-accessories to buy cables and accessories for t is product.
DC Power Supply
T is module uses 3.3V precision voltage regulator. By default the board is configured to
use +5V supply from USB. So an external +5V power is not required unless USB port is
unable to supply enough current. In most cases USB ports are capable of providing
enough current for the module. If for any reason, an external power supply needs to be
used for t e logic section of t e module, t e power select jumper K1 s ould be configured
properly before connecting t e power supply. Make sure to connect t e power supply in correct
polarity. Connect t e positive terminal of t e power supply to t e +5V terminal on t e module.
Using a product similar to Numato's DC Barrel Jack Adapter is recommended if
t e power supply as a Barrel Jack connector (See t e image on rig t).
Connecting power supply incorrectly can cause damage to t e module and/or ot er devices.
JTAG Connector
JTAG connector provides access to Microcontroller's JTAG pins. A XILINX platform cable can be used to
for JTAG programming.

GPIOs
T is board is equipped wit 47 GPIO pins t at can be used for various custom applications. T e
module as GPIO pins available on separate square pads for easy prototyping. Some of t ese pins can
be used as Analog to Digital Converter inputs as well. In output mode, eac digital IOs can source up
to 25mA. So no additional circuitry is needed to drive regular LED's. A 470 O ms series resistor is
recommended for current limiting w en connecting LED to an IO.
In contrast to GPIOs Analog inputs can read voltages at any level between 0 to 3.3V volts. It is
recommended to use a series resistor to protect t e input from stray voltages and spikes. T e internal
Analog to Digital converter supports 10 bits resolution w ic is adequate for most applications. T e
table below summarizes t e GPIOs input positions on t e terminals. Pin assignments on t e
connectors are available in t e tables below.

How to upload firmware
Most of Numato Lab's USB based products are s ipped wit pre-programmed bootloader to elp wit
field firmware updates. Please follow t e steps below to update t e firmware on your product.
1. Identify if your device supports field firmware upgrade
Only USB based devices support field firmware update at t is time. If t e device does not ave
a USB connector, c ances are t at t e device does not support field firmware update. Not all
USB based devices guaranteed to ave field firmware update support eit er. If t e device
support field firmware update, t ere s ould be a two pin eader or pus button switc on
board wit name similar to “FWUP” or “FWUPDATE”. T oroug ly inspect t e board and c eck
if suc a eader is present. If t ere is no suc jumper is present, c ances are t at t e device
does not support field firmware update. See examples of firmware update eader below.

•MS VC++ 2008 redistributable package
•MS .Net Framework 2.0
Skip t is step if t ese packages are already installed on your mac ine. Installers for t ese two
packages are available under “prerequisites” folder in t e zip package t at is provided wit t is
document. Run t e appropriate installers and follow on screen instructions to complete
