5.1 Power Pins

It is recommended that a bulk and a decoupling capacitor be added at the input supply pin (V_DD, VDD_A and GND pins) of the RNBD350 Module.

• The recommendation is to have a 4.7 μF on the VDD_A pin, 4.7 μF and a 0.1 μF on the V_DD pin.
• The value of the capacitors are based on typical application requirements and are the minimum recommended values. Depending on the application requirement (in other words, a noisy power line or other known noise sources), the user can adjust the values of the capacitor to provide a clean supply to the module.
• Place all the capacitors close to the module power supply pins.
