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.
