BL3362T-P Hardware Information 4.1. Footprint Sequence Please refer to Fig 1 for the footprint sequence of BL3335-P.
-9- 4.2. Footprint Definitions Please refer to Table 16 for the footprint definitions of BL3335-P.
- 10 17 TX0 18 GND GPIO_27 DOWN Note: 1. In default, UART2 (pin1 and pin2) are used for bypass communication and UART0 (pin16 and pin17) are used for output of debugging information and burning firmware. Please refer to the description in DC Characteristics for UART output current level. 2. PDN is hardware reset for the module and will be effective with VIL. Configuration information will be remained after module reset. The module has pull-up process for PDN designed internally. 3.
- 11 - Fig 2 BL3335-P Antenna The gain of PCB antenna on this module is about 0dB, as shown in Fig Fig 3. Fig 3 Simulated radiation pattern of antenna gain The following precautions should be considered during designing with PCB antenna: 1. Do not place any electrical components or grounding in antenna area on main board and it’s better to leave this area blank on PCB. 2.
- 12 antenna and not design any circuit or bond copper on main board under this area. 3. Do not use the module inside any metal case or containers with metal painting. 4. Keep the antenna of wifi module next to the edge of main board during design of PCB to ensure better performance of antenna, as illustrated below. Module Device PCB Fig 4 BL3335-P Recommended PCB layout 4.4. Mechanical Dimensions Please refer to Fig Fig 5 for the dimensions of BL3335-P module.

- 14 - 5. Reference Design 5.1. UART Interface Design For devices with 3.3V power supply, you can directly connect the device UART port with module UART port according to the illustration in Fig Fig 7. External MCU Wi-Fi module Capacitor Grounding Fig 7 Circuit diagram (3.3V) If your device is powered by 5V, you can refer to the circuit shown in Fig Fig 8 or design your own circuit for power conversion. The value of resistor can be adjusted according to actual circuit design.
- 15 - Fig 8 Circuit diagram (5V) 5.2. Power Supply Requirement If an LDO is used to supply the module with 3.3V power, C1 capacitor can be considered to be used with 10u-22u; If a DCDC is used to supply 3.3V power, C1 capacitor can be considered to be used with 22uF. It is recommended to supply the module with power higher than 400mA to ensure enough power supply to the module and avoid power down during data transmission.
