ML3369T-P Hardware Information

PIN Sequence

Please refer to Fig 1 for the pin sequence of ML3369T-P.

Fig 1 ML3369T-P pin sequence

PIN Definitions

Please refer to Table 16 for the hardware pin definitions.

Table 16 ML3369T-P pin definitions

Note:

1. In default, UART is used for output of debugging information and burning firmware. Please refer to the description in DC Characteristics for UART output current level.
2. The pins for reset button and LED indication should be defined according to actual firmware and circuit design.
3. The ADC is 10-bit with input voltage 0-2V
4. The power supply VDD should not be lower than 3.3V.

PCB Antenna

The module support PCB antenna in 2.4G~2.5G frequency with S11 port less than -10dB and max gain of 0.6dB at 2.45GHz.
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 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.

Mechanical Dimensions

Please refer to Fig 2 for the dimensions of ML3369T-P module.

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.

Information to Users
This device complies with Part 15 of the FCC Rules. 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 complies with FCC &IC RSS-102 radiation exposure limits set forth for an uncontrolled environment. This equipment should be installed and operated with minimum distance 20cm between the radiator & your body.

2.2 List of applicable FCC rules
FCC Part 15.247

2.6 RF exposure considerations
This equipment complies with the FCC RF radiation exposure limits set forth for an uncontrolled environment. This equipment should be installed and operated with a minimum distance of 20cm between the radiator and any part of your body.

2.8 Label and compliance information
FCC ID label on the final system must be labeled with “Contains FCC ID: 2AXPC-ML3369T-P” or “Contains transmitter module FCC ID: 2AXPC-ML3369T-P “.

2.9 Information on test modes and additional testing requirements
Contact SHENZHEN YUECHUANGKONGJIAN TECHNOLOGY CO.,LTD will provide stand-alone modular transmitter test mode. Additional testing and certification may be necessary when multiple modules are used in a host.

2.10 Additional testing, Part 15 Subpart B disclaimer
To ensure compliance with all non-transmitter functions the host manufacturer is responsible for ensuring compliance with the module(s) installed and fully operational. For example, if a host was previously authorized as an unintentional radiator under the Supplier’s Declaration of Conformity procedure without a transmitter certified module and a module is added, the host manufacturer is responsible for ensuring that the after the module is installed and operational the host continues to be compliant with the Part 15B unintentional radiator requirements. Since this may depend on the details of how the module is integrated with the host, SHENZHEN YUECHUANGKONGJIAN TECHNOLOGY CO.,LTD shall provide guidance to the host manufacturer for compliance with the Part 15B requirements.
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.
