1. OVERVIEW 1.1. Advisory Symbols Warning! Improper usage or handling may cause non-compliant device operation. Direct Current (DC). 1.2. Module Identification The label contains the CalAmp part number, serial number, IC and FCC ID numbers. Additional labeling will be required on the end device.
1.3. General Description The CalAmp WPAN Module is a short range communication module based on the IEEE 802.15.4 specification. The CalAmp Module is designed to be easily integrated into various end devices. This document describes the process and rules for integrating the WPAN module into an end device. It includes descriptions of all external interfaces and instruction on how to communicate with and power the device. This document does not cover the software functionality of the device.

2. EXTERNAL INTERFACES 2.1. Mechanical Connection There are two 10 pin, through hole, board to board connectors on the module that are used both for communication, power, and mechanical mounting of the module. The two board to board connectors are the Molex 22-28-4100. The pins on the I/O connectors can be soldered directly to the mating PCB. The module can also plug into a mating connector for the 22-28-4100. There are several options available from Molex for a mating plug.
2.3 Power The module must be powered externally with a DC voltage between 3.3 and 5.5VDC. The current draw of the module is listed below. Transmit Peak = 250mA Receive = 50mA Standby = 25mA Sleep = <1mA 2.4 External I/O The Calamp WPAN Module contains a variety of digital and analog external I/O. This I/O can be used to interface with external sensor or logic. Unless otherwise noted the following ratings cover the following pins (GPIO1-6, SYSRESET, PWR_ENABLE, UART, and SPI).
2.5 System Reset The module can be reset by holding pin J3-6 low for at least 26uS. This pin contains an internal 10K pullup. 2.6 Power Supply Enable The power supply on the module can be shut down by holding the PWR_ENABLE line low. The supply will remain disabled as long as the line is held low and will restart when the line goes high. This will have the same effect as resetting the device. This pin contains an internal 10K pullup 2.
3.0 GENERAL INSTALLATION GUIDELINES Refer to module overview images, Figures 1 and 2, for locations of mounting holes. The WPAN module is mounted be either soldering the through hole pins of J3 and J2 to a mating PCB or to a mating connector on a PCB. Refer to the mechanical outline below for connector placement and spacing. Refer to Molex documentation for additional information on PCB footprints for the 2228-4100 connector.
Antenna Considerations: When using a surface mount antenna, the module must be mounted in a way that the antenna may radiate away from other ground planes or metal in the system. For best results, keep ground planes and other metal objects as far from the antenna as possible. When using a external cabled antenna, use only antennas approved by Calamp for use with this module.
