interfacing Ez430-RF2500 with Drv8821 and single layer pcb layout design

Other Parts Discussed in Thread: DRV8821

Hi,

I am intending to design an open loop control system (Robotic arm) using two stepper motors and control them in real time  wireless  using Ez430_rf2500.I would like to have suggestions.

1) I am designing a single layer or two layers PCB for driver circuit using Drv8821 for protoyping.

2) Ez430 - RF2500's, Access Point (AP/  transreceiver) for sending Data from PC to End Device(ED/ transreceiver) and ED would process the data and generate control signals for the driver for stepper motor.Most of the Demo Eg. Using Ez430-RF2500 are in low power applications in sensing and sending back sampled data to AP once per second. So I would like to know precautions to be taken while interfacing it with driver(high power and real time application).

Thank You
