This ZigBee radio module has a 32-Bit ARM Processor and its architecture reduces component amounts on the PCB which ultimately reduces power consumption and the overall cost of these efficient modules. This package needs an external crystal and there’s room for an optional 50 Ohm antenna as well. The two onboard ADCs and 8 general purpose IO pins make this an even more handy interface than the current ZigBees to get started with wireless projects.
