2.1 Technical Description:
RM900 can work at 868MHz, 1 channel, channel spacing 2MHz. It can also work
at 902 ~ 924MHz, 10 channels, channel spacing 2MHz. Users can change its TX
power, working channel through com tool. RM900 is a high sensitivity IEEE
802.15.4/ZigBee module. A combination of Atmel’s MCU SMD21 and RF
transceiver AT86RF212B, the RM900 offers superior radio performance.
The module contains Atmel’s SAMD21 Cotex-M0 Microcontroller, AT86RF212B
RF transceiver. The module can be easily mounted on a simple 2-layer 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.
