INTRODUCTION
MOD- IGBEE features a bundle of 8bit PIC18 processor and an 802.15.4
compatible radio module that makes it easy to develop applications based on RF
communication and especially igBee based protocol stacks. In addition MOD-
IGBEE implements an on-board digital temperature sensor, for remote
temperature reporting.

ELECTROSTATIC WARNING
The MOD- IGBEE board is shipped in protective anti-static packaging. The board
must not be subject to high electrostatic potentials. General practice for working
with static sensitive devices should be applied when working with this board.
BOARD USE REQUIREMENTS
Cables: The cable you will need depends on the programmer/debugger you
use. If you use PIC-ICD2-POCKET or PIC-Kit3 you will need 1.8 m A-
B USB cable.
Hardware: One of Olimex programmers/debuggers – PIC-ICD2-POCKET, PIC-
KIT3, or other compatible programming/debugging tool. Also
note that you would need adapter for the small ICSP connector (0.05''
step) - PIC-ICSP
Software: MPLAB IDE

BOARD LAYOUT
POWER SUPPLY CIRCUIT
MOD- IGBEE may be power supplied in different ways: 2.4V - 3.6V via EXT_PWR;
via ICSP connector (useful for debugging); via BAT connector with +3V Lithium
battery (CR2032).
The programmed board power consumption is about 30mA with RF transceiver
active, and 10µA in deep sleep mode.
CLOCK CIRCUIT
Crystal Quartz 20 MHz connected to MRF24J40 pin 33 (OSC2) and pin 34 (OSC1).
RESET CIRCUIT
MOD- IGBEE reset circuit includes PIC18F26K20 pin 1 (MCLR#/VPP/RE3), R1
(10k) – pull-up, C21 ( D8.2V/0.2W), R2 (330 Ohm), ICSP connector pin 1 and RST
button.

AVAILABLE DEMO SOFTWARE
Available at https:// www.olimex.com
This sample project demonstrates the functionality of the onboard processor, the
radio transceiver and the thermometer. The demo is built upon the following
Microchip's freely distributed support libraries:
- Microchip MiWi Development Environment version 3.1
The demo defines 2 types of devices: Coordinator and End Devices.
According to Microchip MiWi specifications the MiWi network requires one
Coordinator and one or many End Devices. The demo consists of separate projects
for the Coordinator (called 'Coordinator') and End Devices (called 'EndDevice').
Upon startup the Coordinator forms a network with PAN ID 0x1234 on the
channel with the least amount of noise, LED1 is lit and the program starts waiting
for client devices to connect. Status messages are printed over UART and can be
displayed on a terminal program on a PC (please see next chapter). The Coordinator
is configured to accept connections from up to 10 devices. The Coordinator accepts
connections from any device that requests joining but will only recognise messages
about name and temperature of end devices using the other part of the demo.
Received and recognised messages are printed on the terminal and LED2 toggles at
any successful reception. Here is a sample terminal log from the operation of a
Coordinator:
-----------------------------------------------------------------------------------------
Input Configuration:
Button 1: RB5
Button 2: RB4
Output Configuration:
RS232 port
LED 1: RA0
LED 2: RA1
RF Transceiver: MRF24J40
Demo Instruction:
Power on the board until LED 1 lights up
to indicate it is ready to establish new
connections. Push Button 1 to perform
frequency agility procedure. Push Button
2 to unicast encrypted message. LED 2 will
be toggled upon receiving messages.

Upon startup an End Device starts searching for a network with PAN ID
0x1234 on any available channel. If such a network is not found then the device
enters deep sleep mode and reattempts connecting after some time. When a suitable
network is found (formed by the Coordinator) the device joins it and sends to the
Coordinator its specific name and measured temperature. Then it enters deep sleep
mode and sends its measured temperature again after some time. The sleep may be
prematurely terminated by a press of any of the two buttons (not the RESET
button!).
If the Coordinator disappears for some reason the end device enters startup
state again.
*Note: With the introduction of MOD-LCD1x9 and MOD- IGBEE rev.B you have
the ability to make an assembly between the to and have status messages and
current temperature value displayed on the LCD, even when deep sleeping. To
enable this feature of the End Device demo just uncomment
"USING_MOD_LCD1x9" in 'main.c'.
Please read README.txt in demo source folder for more details.
