WMD40R201xx6PC HY-40R201PC PCB Antenna

5. FCC ID & IC ID & CE & BQB print format on the shield case:

6. PCBA dimension size and picture HY-40R201PC / WMD40R201xx6PC( PCB F Antenna)

(PCBA dimension size : 17.9*11.59*2.0mm).

7.Application Note:

7-1.Attention to the electrostatic protection, prevent the soldering iron and the equipment

grounding bad; And the workbench, working environment, packaging materials and from the

human body Touch with static electricity, etc., destroy IC and software to be flied; Manual

welding module solder iron temperature, should pay attention to avoid the PCB copper

stripping off;Soldering iron strictly Grounding requirements, eliminating solder iron leak voltage

and avoid supply power Vcc switch instant turn on/ turn off state ,generate high voltage,May

be let the module to damaged;

7-2.Attention to avoid the overall motherboard power supply circuit of bad welding connected to

short circuit or open circuit, causing the Bluetooth chip, abnormal voltage,Thesoftwarewill fly

and problems of IC was damaged.

7-3.When programming firm ware , the VDDS supply voltage must in DC 2.4~3.3V, To avoid

programming has not completely, and abnormal status occur.

7-4. Avoid supply voltage in ( BOD Brown - Out Dectect) fall within the scope of electrical detection

threshold (1.76 V ~ 1.78 V) occurred many times, ( diagram below off electric Lock - up area)

firmware may be locked.

Cause the Boot Code startup Code suspended, unable to connect to the JTAG protocol,;In

case of this state is available use Reset pin action under 1.0 V, to remove this phenomenon;

The rechargeable batteries at charge-discharg status; In the application at the same time, to

ensure the voltage setting of the protection system; And pay attention to the supply of power

caused by the internal resistance and line impedance voltage drop; And make sure that
