CHAPTER VI. BOARD MOUNTING RECOMMENDATION
VI.1. Electrical environment
The best performances of the ZE51/61-2.4 module are obtained in a “clean noise” environment. Some basic
recommendations must be followed:
 Noisy electronic components (serial RS232, DC-DC Converter, Display, Ram, bus ,...) must be placed as
far as possible from the ZE51/61-2.4 module.
 Switching components circuits (especially RS-232/TTL interface circuit power supply) must be decoupled
with a 100 µF tantalum capacitor. And the decoupling capacitor must be as close as possible to the noisy
chip.
