Description:

Product Model:DL-20 Chip: CC2530F256RHAR Working frequency: 2400 - 2450MHZ Transmitting power: 4.5dBm Transmission rate: up to 3300 Bps Transmission distance: measured 250 meters Wide voltage range: 3V - 5.5V TTL level adaptive Operating current: less than 30mA Support working mode: point-to-point working mode, broadcast working mode Communication interface: UART serial data Baud rate: 2400 4800 9600 14400 19200 38400 57600 115200 Working Channel: 16 channel divisions in accordance with IEEE 802.15.4 protocol Receiver sensitivity: -97dBm Point-to-point bit error rate: 0% Broadcast bit error rate: 0.5% Antenna Interface: Built-in PCB Antenna Working temperature:-40C - 80C Size: 16 * 32 mm (Excluding pinout) Packet length: support serial transmission, unlimited length   Key configuration Use the onboard buttons to set the module's channel, baud rate, and operating mode   Support serial port uninterrupted penalty, unlimited length DL-2X wireless serial passthrough module supports uninterrupted transmission, hundreds of KB files transfer at 38400 baud rate without any pressure, without any data loss   Point-to-point operation mode Transmission with acknowledgment mechanism to achieve 0 packet loss rate In the peer-to-peer mode, the DL-20 module uses the negotiating Mac protocol to send and receive simultaneously in both directions. In point-to-point operation mode, it is divided into A end and B end. The data sent from the serial port to the A side will be sent to the B side by wireless transmission. The B side will send the received data to the serial port, and vice versa. In this mode, only two nodes can communicate with each other on the same channel. When data is sent, the red light on the right side of the module will flash.   Broadcast mode A one-to-many or multiple-to-one mode can be implemented. In the broadcast mode, data input to one module on the serial port will be converted to wireless data. All modules in the nearby channels that receive the same data will receive this data and send the data out of their serial ports. In the broadcast mode, the serial port data received by one module is sent to all other modules whose channels and work modes are the same. The module that receives the data outputs data from the serial port. In this mode, the data will have a bit error rate of about 1%. When multiple modules send data at the same time, the bit error rate will increase significantly. When the data is sent, the red light on the right side of the module will flash. When the data is received, the right green light will flash.     Package included:   1*DL-20 CC2530 2.4G Remote Wireless Serial Transceiver Module Data Transmission Module TTL 30mA Board CC2530F256RHAR Chip
