433Mhz UART Wireless Transceiver Module with PAN3028 Chip
Product Description
Brief Introduction
This DL-P3028M RF module is an UART Transceiver Module, which was designed base on high-performance PAN3028 RF chip and built-in HC32L130 low-power MCU. It is an UART Module with AT command, which supports a maximum power output of 22dBm and a sensitivity of -140dBm; it is an effective wireless module which can provide excellent RF performance and strong anti-interference performance in the 398-510MHz frequency band.
Features
● Support AT commands for configuration, easy to develop and debug;
● Support transparent transmission mode for data transmission;
● Support data flow control in transparent transmission mode (AUX);
● Typical serial baud rate (such as 9600/19200/38400/57600/115200bps) is supported;
● Multiple wireless baud rate is supported;
● Wake-on-Radio (WOR) function supported (intermittent receiving), which can be greatly increases the battery standby time;
● Support CAD (Automatic Radio Frequency Signal Detection) to reduce the probability of signal collision;
● Can achieve fixed point transmission, broadcasting and other transmission methods;

Application Connection Diagram
Notice for Pin Connection:
1. PIN9 & PIN10 of DL-P3028M and DL-P3028MPA are the same (ANT, GND), but the position of the pins on the module packaging is different.
2. RX and TX are used for data transmission and should be inversely connected with the UART pins of external MCU.
3. AUX, SETA, SETB and RESET are used for the module control, which need to be connected with the GPIO port ofthe external MCU.
4. SETA and SETB are high level defaulted. When the Wireless Module enters sleep mode, these two Pins need to beconnected to certain levels;otherwise, electric leakage will occur.
Typical application
Wireless Data Communication, Wireless Remote Control System; Wireless Alarm & Security Control System; Wireless Sensor Networking, Automatic Data Collection; Industrial Remote Control, Intelligent Control System, Home Automation, Smart Building, Smart Home, Smart City, Telemetry, Automatic (Water, Electricity, Gas) Meter Reading;
