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.

•RF Transceiver – MRF24J40 IEEE 802.15.4™ standard compliant 2.4

GHz RF transceiver

•ICSP connector

•On-board antenna

•On-board temperature sensor – TCN75A

•Option for external power supply through EXT_PWR

•EXT/BAT switch

•Reset circuit

•two user buttons

•two status LEDs

•RST button

•+3V lithium battery holder

•PCB: FR-4, 1.00 mm (0,039"), solder mask, silkscreen component print

•Dimensions: 65.15x20.38 mm (2.56x0.80")

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
