2.1 Technical Description:

RM900B_M1 can work from 863~870MHz.Typical frequent is 865.6MHz,

866.4MHz, 868.3MHz and 869.0MHz. It can also work at 902 ~ 924MHz, 10

channels, channel spacing 2MHz. Users can change its TX power, working

channel through com tool. RM900B_M1 is a high sensitivity IEEE

802.15.4/ZigBee module. RM900B_M1 integrates RM900B_M5 modem which is

a combination of Atmel’s MCU SMD21 and RF transceiver AT86RF212B, the

RM900B_M1 offers superior radio performance.

The sub module RM900B_M5 contains Atmel’s SAMD21 Cotex-M0

Microcontroller, AT86RF212B RF transceiver. The module can be easily

mounted on RM900B_M1 PCB with a minimum of required external connection.

Neither via-holes nor wires are allowed on the PCB upper layer in area occupied

by the module. As a critical requirement, RF_GND pins should be grounded via

several holes to be located right next to the pins thus minimizing inductance and

preventing both mismatch and losses.
