Introduction 1

MicroRidge 2.4 GHz Radio Module

Version 1.3.9

1 Introduction

The MICRO-RM2.4 Radio Module from MicroRidge Systems is a small wireless module based

on the Atmel ATmega2564RFR2 microcontroller. The ATmega2564RFR2 is a low-powered

CMOS 8-bit microcontroller based on the AVR enhanced RISC architecture combined with a high

data rate transceiver for the 2.4 GHz ISM (industrial, scientific and medical) band.

The MICRO-RM2.4 contains an on-board chip antenna. The module contains radio certifications

for FCC, IC and EU (CE). No additional RF testing is required as long as the application of the

MICRO-RM2.4 follows the approved certifications.

The small size of the MICRO-RM2.4 module allows it to be used in small and compact products.

The module measures 12 x 20.75 x 3 mm (.472 x .817 x .118 inches). The module requires a

power supply of 1.8 to 3.6 volts DC. This voltage range allows the module to be powered by a

single 3 volt coin cell or two 1.5 volt batteries.

Additional information is available about the MICRO-RM2.4 Radio Module components and

supporting software from the following sources:

A complete description of the ATmega2564RFR2 microcontroller used in the module is

available on the Atmel web site (www.atmel.com). The document describing this

microcontroller is ATmega644/1284/2564RFR2 42073B-MCU Wireless. The document

number (42073B-MCU) is updated by Atmel when changes are made to the document.

Atmel also has additional documentation available that may be helpful in developing

wireless applications for the MICRO-RM2.4 module.

The MicroRidge MICRO-RM2.4 Wireless Communication Library (RM2.4 Library) is

available to assist in the development of firmware for the MICRO-RM2.4 Radio Module. In

order to use the RM2.4 Library, you must purchase Radio Modules that have the library

support enabled. This library is only supported on specific versions of the IAR Embedded

Workbench for the AVR microcontroller. Refer to the Wireless Library section in this

manual for more information.

Additional documentation and information dealing with the MICRO-RM2.4 Radio Module

will be available at www.MicroRidge-RM.com during the 3rd quarter of 2015.
