PUDU 2.4G RF communication module Product specification Description: 2.4G communication module Product:

model:CMMC01 Version: 1.0 Prepared on: 2022.01.21 Chapter 1 Module Introduction 1.1 Introduction The BL268T-H4 is an industrial UART wireless pass-through module with high stability. The module uses Semtech SX1280/SX1281 devices with LoRa spread spectrum transmission and TTL level output. Compared with other 2.4G communication technologies, LoRa direct sequence spread spectrum technology has the advantages of low power consumption, longer communication distance and strong anti-interference ability. The module supports the PUDU LoRa TSCH standard communication technology, and can be used as a common transparent LoRa module, and can also greatly improve the anti-interference performance and bandwidth utilization under the PUDU LoRa TSCH communication system. BL268T-H4 has a working frequency range of 2400MHz ~ 2500MHz, and each channel has an interval of 300KHz. Various parameters such as working mode, transmitting and receiving frequency, transmitting frequency and RF speed can be modified online. 1.2 Functional characteristics Free operating frequency band The maximum transmission power is 12.5dBm, which is adjustable by software. Maximum receiving sensitivity -130 dBm Support PUDU LoRa TSCH communication standard and support stable transmission in high-bandwidth environment Support frequency 2400MHz ~ 2500MHz Industrial standard design, operating temperature -40 ~ + 85 1 2 3 4 5 6 7 8 9 10 11 12 Supply voltage Operating frequency band Communicati on level Reference distance Transmittin g power Receive sensitivity Air speed Emission current Communicati on interface Packet length Module address 1.3 Electrical parameters Parameter name Seria l numbe r Parameter value details 2.8V3.6V 2400MHz ~ 2500MHz 3.3 V TTL level Classical environment (SF7BW203) 100 m (test conditions: clear, open, maximum power Rate, antenna gain 2dBi, height greater than 2m) 12.5d Bm Max, adjustable

(2) this device must accept any interference received, including interference that may cause undesired operation. Any Changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate the equipment. The modular can be installed or integrated in mobile or fix devices only. This modular cannot be installed in any portable device. Note: 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. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment 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 equipment 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. FCC Radiation Exposure Statement This modular complies with FCC RF radiation exposure limits set forth for an uncontrolled environment. This transmitter must not be co-located or operating in conjunction with any other antenna or transmitter. This modular must be installed and operated with a minimum distance of 20 cm between the radiator and user body. The module is limited to OEM installation only The OEM integrator is responsible for ensuring that the end-user has no manual instructions to remove or install module 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:2AXDW-CMMC01 Or Contains FCC ID: 2AXDW-CMMC01 When the module is installed inside another device, the user manual of the host must contain below warning statements;

1. 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.

(2) This device must accept any interference received, including interference that may cause undesired operation. 2. Changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate the equipment. The devices must be installed and used in strict accordance with the manufacturer's instructions as described in the user documentation that comes with the product. Any company of the host device which install this modular with limit modular approval should perform the test of radiated emission and spurious emission according to FCC part 15C : 15.247 and 15.209 requirement, Only if the test result comply with FCC part 15C :

15.247 and 15.209 requirementthen the host can be sold legally. Antennas:
