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. In default, PIN13 (GPIO8) is the PIN for external LED indicator to show the module configuration status and output VIH after configuration is successful. 4. In default, PIN14 (GPIO5) is the module software reset PIN and will be effective with VIH. The previous configuration information will be cleared after the module is reset (reset to factory settings). 5. The module supports max 4 channels of external interruption simultaneously except GPIO25 and UART0. 6. The ADC is 10bit with input voltage 0-2V 7. The power supply VDD should not be lower than 3.3V. 4.3. PCB Antenna Please refer to Fig 2 for PCB antenna. Please avoid to place any electrical components, wiring or grounding under PCB antenna area on main board and it’s better to leave this area blank on PCB. - 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. It is recommended to not place any electrical components within 30mm range of module - 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.

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. - 16 - Revision History Date Jan 12, 2018 Version 1.0 Updated Content Preliminary version Copyrights It is prohibited to use or copy all or any part of contents in this manual without prior permission, especially applicable for trademarks, models, part numbers and figures.

Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) This device must accept any interference received, including interference that may cause undesired operation. Note: This product has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This product generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this product does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures: —Reorient or relocate the receiving antenna. —Increase the separation between the equipment and receiver. —Connect the equipment into an outlet on a circuit different from that to which the receiver is connected. —Consult the dealer or an experienced radio/TV technician for help. Please take attention that changes or modification not expressly approved by the party responsible for compliance could void the user’s authority to operate the equipment. This equipment should be installed and operated with a minimum distance 20cm between the radiator and your body - 18 - This device complies with Industry Canada licence-exempt RSS standard(s). Operation is subject to the following two conditions: (1) this device may not cause interference, and (2) this device must accept any interference, including interference that may cause undesired operation of the device. Le présent appareil est conforme aux CNR d'Industrie Canada applicables aux appareils radioexempts de licence. L'exploitation est autorisée aux deux conditions suivantes : (1) l'appareil ne doit pas produire de brouillage, et (2) l'utilisateur de l'appareil doit accepter tout brouillage radioélectrique subi, même si le brouillage est susceptible d'en compromettre le fonctionnement. Under Industry Canada regulations, this radio transmitter may only operate using an antenna of a type and maximum (or lesser) gain approved for the transmitter by Industry Canada. To reduce potential radio interference to other users, the antenna type and its gain should be so chosen that the equivalent isotropically radiated power (e.i.r.p.) is not more than that necessary for successful communication. Conformément à la réglementation d'Industrie Canada, le présent émetteur radio peut fonctionner avec une antenne d'un type et d'un gain maximal (ou inférieur) approuvé pour l'émetteur par Industrie Canada. Dans le but de réduire les risques de brouillage radioélectrique à l'intention des autres utilisateurs, il faut choisir le type d'antenne et son gain de sorte que la puissance isotrope rayonnée équivalente (p.i.r.e.) ne dépasse pas l'intensité nécessaire à l'établissement d'une communication satisfaisante. The module is limited to OEM installation ONLY The OEM integrator is responsible for ensuring that the end-user has no manual instruction to remove or install module. When the FCC identification number or ISED certification number is not visible when the module is installed inside another device, then the outside of the device into which the module is installed must also display a label referring to the enclosed module. This exterior label can use wording such as the following: “Contains FCC ID: 2ACDZ-BL3335-P or ”Contains IC: 23239-BL3335P and the information should be also contained in the devices’ user manual.
