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.

RM2.4 Radio Module Logo Requirements for MobileCollect Compatible Products

The following RM2.4 logo may be required to be displayed on products that use the RM2.4 Radio Module.  This requirement only applies to products that are compatible with the MicroRidge MobileCollect product line.

If you are using the RM2.4 Radio Module with application firmware developed by MicroRidge for use with the MobileCollect product line, the RM2.4 logo must be displayed on the product label.  By displaying the RM2.4 logo on the product, it will help the user to identify products compatible with MobileCollect.

If you are developing your own application firmware and the product will be compatible with MobileCollect, it is strongly recommend that you put the RM2.4 logo on your product.

Short Range Devices (ETSI)

The MICRO-RM2.4 Radio Module is classified as a short range device by ETSI (European Telecommunications Standards Institute).

Short Range Devices (SRD) are radio devices that offer a low risk of interference with other radio services, usually because their transmitted power, and hence their range, is low. Short range devices often benefit from a relaxed regulatory regime compared with other radio communications equipment.  The definition ‘Short Range Device’ may be applied to many different types of wireless equipment, including various forms of:

• Access control (including door and gate openers)
• Industrial controls
• Local Area Networks
• Remote control Radio frequency identification (RFID)
• Telemetry
• Plus numerous other devices
