Introduction
Numato Lab's PIC32 MX Development board with Microchip HID boot loader preprogrammed is a
versatile product for controlling electrical and electronic devices remotely from a PC over USB link.
This board can be conveniently powered by USB or by an external power supply for standalone
applications. Preprogrammed boot loader helps you to start testing your programs without even
buying a programmer. Ease of use and wider operating system compatibility are the primary goals
behind this product's design. Built in USB to serial conversion allows the module to be used without
any USB specific knowledge.

How to use the module
The following section describes how to use this module.
Components/Tools required
Along with the module, you may need the items in the list below for easy and fast installation.
1. USB A to Mini B cable.
2. Medium size Philips screw driver.
Connection Details
IMPORTANT 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 shows basic connection diagram that can be used in most of the situations. Use a USB A
to Mini B cable for connection to PC. The following sections identify individual connections in detail.

USB Interface
The on board full speed USB controller helps a PC/Linux computer to communicate and
control this module seamlessly. Use a USB A to Mini B cable to connect with a PC. By
default, the logic section of the module is powered from USB so make sure not to
overcrowd unpowered USB hubs(the picture on the right shows USB Mini B connector).
Visit http://numato.com/cables-accessories to buy cables and accessories for this product.
DC Power Supply
This 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 the logic section of the module, the power select jumper K1 should be configured
properly before connecting the power supply. Make sure to connect the power supply in correct
polarity. Connect the positive terminal of the power supply to the +5V terminal on the module.
Using a product similar to Numato's DC Barrel Jack Adapter is recommended if
the power supply has a Barrel Jack connector (See the image on right).
Connecting power supply incorrectly can cause damage to the module and/or other devices.
JTAG Connector
JTAG connector provides access to Microcontroller's JTAG pins. A XILINX platform cable can be used to
for JTAG programming.

GPIOs
This board is equipped with 47 GPIO pins that can be used for various custom applications. The
module has GPIO pins available on separate square pads for easy prototyping. Some of these pins can
be used as Analog to Digital Converter inputs as well. In output mode, each digital IOs can source up
to 25mA. So no additional circuitry is needed to drive regular LED's. A 470 Ohms series resistor is
recommended for current limiting when 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 the input from stray voltages and spikes. The internal
Analog to Digital converter supports 10 bits resolution which is adequate for most applications. The
table below summarizes the GPIOs input positions on the terminals. Pin assignments on the
connectors are available in the tables below.

How to upload firmware
Most of Numato Lab's USB based products are shipped with pre-programmed bootloader to help with
field firmware updates. Please follow the steps below to update the firmware on your product.
1. Identify if your device supports field firmware upgrade
Only USB based devices support field firmware update at this time. If the device does not have
a USB connector, chances are that the device does not support field firmware update. Not all
USB based devices guaranteed to have field firmware update support either. If the device
support field firmware update, there should be a two pin header or push button switch on
board with name similar to “FWUP” or “FWUPDATE”. Thoroughly inspect the board and check
if such a header is present. If there is no such jumper is present, chances are that the device
does not support field firmware update. See examples of firmware update header below.

Install prerequisites
The firmware upgrade application currently supported on Windows only. It is important to
make sure that all prerequisites are installed before running the application. Following needs
to be installed before continuing with firmware upgrade.
• MS VC++ 2008 redistributable package
• MS .Net Framework 2.0
Skip this step if these packages are already installed on your machine. Installers for these two
packages are available under “prerequisites” folder in the zip package that is provided with this
document. Run the appropriate installers and follow on screen instructions to complete
installation.
3. Connecting your hardware to the PC
To activate the bootloader present on the device, press the firmware update push button
switch. Once it is short circuited, connect the device to the PC using an appropriate USB cable.
Please note that when bootloader is activated, normal features and functions will not be
accessible.

4. Downloading the firmware
Run downloader.exe found under bin folder. If everything is setup correct, you should be
presented with the following screen.
If you are unable to run the application, please make sure that all prerequisites are installed. If
the “Open Hex File” button is grayed out, it means that the bootloader on the device is not
activated. Please make sure that the device support field firmware update and revisit step 4 to
properly connect the device to PC.
To download the firmware, click on the “Open Hex File” button, browse and select the hex file
for the product. When the hex file is selected, the “Program/Verify” button should activate.
Click the “Program/Verify” button to complete firmware download.
