ZigBee module with 32-Bit ARM Processor is ideal for remote sensing. California Eastern Laboratories is the only company that offers an IEEE 802.15.4 wireless module with an internal 32-Bit ARM processor. The module named FreeStar Pro is based on Freescale Semiconductor’s MC13224V radio/processor Platform in Package (PiP) chip. It offers lots of memory and I/O ports making it simple to design complex wireless nodes. |

PCB (printed circuit board) layout optimization to avoid EMI (electromagnetic interference). A PCB layout should not only strive to prevent the emission of noise but also have good noise immunity from outside sources. One should have an understanding of potential sources of noise and have a strategy for dealing with these problems. |
