TI recommends the following guidelines for the power supply of the CC2564MODx module:
• Use a star pattern format to supply power to the different pads of the module.
• Keep the power traces (VBAT and VIO) more than 14 mils.
• Use short power supply traces.
• Place decoupling capacitors as close as possible to the module (see Figure 6-10).
