2BBCH-ZKBM01Bluetooth module

1 Product Introduction 1.1 overview ZKBM01 is a highly integrated BLE Bluetooth transparent module with features such as small size, low power consumption, and ease of use, helping users develop Bluetooth applications at the lowest cost and fastest speed. After the module is started, it will automatically broadcast, and mobile devices can scan and connect it. After successful connection, users can communicate in both directions between the module and the mobile device. 1.2 Application scope Smart Home Related Products General LED lighting control for smart home related products, intelligent lighting such as Tmall Genie Logistics tracking, warehouse inspection, electronic labels, etc Wireless data acquisition and control of industrial instruments and meters Wireless remote control and voice remote control for electronic consumer products Wireless alarm and security system 1.3 pinouts Serial Number name types of describe 1 BLAS --- Retention function 2 MIC --- Retention function 3 A_P voice speaker+ 4 A_N voice speaker- 5 RST --- Reset foot 6 GND GND Power- 7 VCC VCC Power+ 8 VDDIO --- --- 9 ALL --- --- 10 ALO --- --- 11 PD7 I/O Retention function 12 PD6 I/O Retention function 13 PD5 I/O Retention function 14 PD4 I/O Retention function 15 DIO I/O Burn-SDA 16 TCK I/O Burn-SCL 17 PC5 I/O Retention function 18 PC3 I/O Retention function 19 PC2 I/O Retention function 20 PC1 I/O Retention function 21 PC0 I/O Retention function 22 PD3 I/O Retention function 23 PD2 I/O Retention function 24 PD1 I/O Retention function 25 PD0 I/O Retention function 26 PB4 I/O Retention function 27 PB6 I/O Retention function 28 PB7 I/O Retention function 29 PB5 I/O Retention function 30 PB1 I/O Retention function 31 PB2 I/O Retention function 32 PB3 I/O Retention function 33 PA3/TX I/O Serial 34 PA2/RX I/O Serial 35 PA1 I/O Retention function 36 PA0 I/O Retention function 37 PA7 I/O Retention function 38 PA6 I/O Retention function 39 PA4 I/O Retention function 40 PA5 I/O Retention function 2 hardware design 2.1 power The power supply voltage range of the module is between 1.8 and 4.3V, and cannot be outside this range. Exceeding this range may permanently damage the module. According to the application needs, the module can be powered separately or shared with the host device, but please choose a better power supply for the ripple system. If using a switching power supply, please pay attention to the interference of switching pulses on the module. Note: Normal working voltage of the module is DC 3.3V 2.2 IO power The module IO port has a TTL level of 3.3V. When connecting to the main control MCU, attention should be paid to level matching. The maximum input voltage that the module IO port can accept is 3.6V, which may damage the module. If the external MCU level is 5V, a transistor voltage conversion circuit or specialized voltage conversion chip can be used to convert it to a matching level and then connect it to the module IO port. For IO ports that are not used by the module, please hover or use a 10K resistor to pull them down to GND. 3 use 3.1 UART 1. The module can be used to upgrade firmware using a PC burning tool and a serial port. The specific operations are as follows: 2. Open the PC serial port burning tool, select the correct serial port number, import the DAT file (select the updated bin file), and then open the serial port to enter the waiting connection state. 3. Connect the TX of the serial tool to the chip PA2 (RXD1 on the module side) and RX to the chip PA3 (TXD1 on the module side). Attention: Because the TX of the serial port tool will be connected to the module end in series, the wiring connection sequence should follow the process described in steps 2 and 3 above, otherwise the module will not be successfully connected. 4 Contact Us Zhongshan Zhikong Intelligent Technology Co., Ltd 地址:Part II, 3rd Building, No.8 Building, No.3 Jiuzhou Avenue, Huoju Development Zone, Zhongshan City FCC Statement This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of the FCC rules.

Modular Approval Request FCC (Per 15.212) FCC ID: 2BBCH-ZKBM01 Items to be covered Answer From Applicant 1. The radio elements of the modular transmitter must have their own shielding. The physical crystal and tuning capacitors may be located external to the shielded radio elements. Yes 2. The modular transmitter must have buffered modulation/data inputs (if such inputs are provided) to ensure that the module will comply with part 15 requirements under conditions of excessive data rates or over-modulation. Yes 3. The modular transmitter must have its own power supply regulation. Yes 4. The modular transmitter must comply with the antenna and transmission system requirements of §§ 15.203, 15.204(b) and 15.204(c). The antenna must either be permanently attached or employ a “unique” antenna coupler (at all connections between the module and the antenna, including the cable). The “professional installation” provision of § 15.203 is not applicable to modules but can apply to limited modular approvals under paragraph (b) of this section. Yes 5. The modular transmitter must be tested in a stand-alone configuration, i.e., the module must not be inside another device during testing for compliance with part 15 requirements. Unless the transmitter module will be battery powered, it must comply with the AC line conducted requirements found in § 15.207. AC or DC power lines and data input/output lines connected to the module must not contain ferrites, unless they will be marketed with the module (see § 15.27(a)). The length of these lines shall be the length typical of actual use or, if that length is unknown, at least 10 centimeters to insure that there is no coupling between the case of the module and supporting equipment. Any accessories, peripherals, or support equipment connected to the module during testing shall be unmodified and commercially available (see § 15.31(i)). Yes 6. The modular transmitter must be equipped with either a permanently affixed label or must be capable of electronically displaying its FCC identification number. (A) If using a permanently affixed label, the modular transmitter must be labeled with its own FCC identification number, and, if the FCC identification 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 Transmitter Module FCC ID: XYZMODEL1” or “Contains FCC ID: XYZMODEL1.” Any similar wording that expresses the same meaning may be used. The Grantee may either provide such a label, an example of which must be included in the application for equipment authorization, or, must provide adequate instructions along with the Yes module which explain this requirement. In the latter case, a copy of these instructions must be included in the application for equipment authorization. (B) If the modular transmitter uses an electronic display of the FCC identification number, the information must be readily accessible and visible on the modular transmitter or on the device in which it is installed. If the module is installed inside another device, then the outside of the device into which the module is installed must display a label referring to the enclosed module. This exterior label can use wording such as the following: “Contains FCC certified transmitter module(s).” Any similar wording that expresses the same meaning may be used. The user manual must include instructions on how to access the electronic display. A copy of these instructions must be included in the application for equipment authorization. 7. The modular transmitter must comply with any specific rules or operating requirements that ordinarily apply to a complete transmitter and the manufacturer must provide adequate instructions along with the module to explain any such requirements. A copy of these instructions must be included in the application for equipment authorization. Yes 8. Radio frequency devices operating under the provisions of this part are subject to the radio frequency radiation exposure requirements specified in §§ 1.1307(b), 1.1310, 2.1091, and 2.1093 of this chapter, as appropriate. Applications for equipment authorization of modular transmitters under this section must contain a statement confirming compliance with these requirements. The modular transmitter must comply with any applicable RF exposure requirements in its final configuration. Technical information showing the basis for this statement must be submitted to the Commission upon request. Yes Note: If compliance with one or more of the numbered requirements, listed above, cannot be demonstrated, it may be possible to obtain a “Limited Modular Approval” (LMA).
