II. Electrical parameter

Electrical Characteristics

Noted BW16 module is an electrostatic sensitive device, which needs special ESD
precautions.When usd ESD protective devices should be added. The correct ESD processing and packaging must be adopted in the transportation, operation and use of BW16 modules. Do nottouch the module by hand or weld with a non-antistatic soldering iron to avoid damage to the module.

1Application Circuit

BW16 V1.0

2Antenna layout requirements 1Installation position on the main boardadvise for following two ways Option 1The module is placed on the edge of the main board, and the antenna area is extended out of the edge of the main board. Option 2Put the module on the edge of the motherboard, and the edge of the motherboard is hollowed out in the antenna position. 2In order to meet the performance of the on-board antenna, metal parts are prohibited from being placed around the antenna.

3Power Supply 1Recommended voltage 5V, Peak:Current over 500mA . 2It is recommended to use the LDO power supplyIf DC-DC is used, the ripple is controlled within 30 mV. 3DC-DC power supply circuit is recommended to reserve the position of the dynamic response capacitor, and the output ripple can be optimized when the load change is large.
4Proposed addition of ESD Devices to 5V Power supply Interface.

4GPIO

(1) At the periphery of the module, some GPIO ports are led out, and a resistance

of 10-100 ohms can be connected in series on the IO port for use. This suppresses

overshoot and is more stable on both sides. Help for both EMI and ESD.

(2) For the up-and-down drawing of the special io-port, reference will be made to the use description of the specification, which will affect the start-up configuration of the module. (3) The IO port of the module is 3.3 v. If the main control does not match the io-level of the module, it is necessary to increase the level conversion circuit. (4) If the IO interface is directly connected to the peripheral interface, or the pins and other terminals, it is recommended to reserve the ESD device near the terminal at the IO trace.
