描述

HC-12 無線串口通信模塊是新一代多通道嵌入式無線數據傳輸模塊。其無線工作頻段為 433.4-473.0MHz,可設置多個通道,步進 400KHz,共有 100 個通道。模塊的最大發射功率為 100mW(20dBm),空中波特率為 5000bps 時的接收靈敏度為-117dBm,開放空間的通信距離為 1000m。

模塊採用壓印孔封裝,可採用貼片焊接,尺寸為 27.8mm×14.4mm×4mm(含天線帽,不含彈簧天線),方便用戶進入應用系統。模塊上有一個 PCB 天線底座 ANT1,用戶可以通過同軸電纜使用 433M 頻段的外接天線;模塊內還有一個天線焊眼 ANT2,方便用戶焊接彈簧天線。用戶可以根據使用要求選擇其中一種天線。

模塊內部有 MCU,用戶無需單獨對模塊編程,所有透明傳輸模式只負責接收和發送串口數據,所以使用方便。該模塊採用多種串口透傳模式,用戶可以根據使用要求通過 AT 命令進行選擇。三種模式 FU1,FU2 和 FU3 在空閒狀態下的平均工作電流分別為 80μa,3.6mA 和 16mA,最大工作電流為 100mA(處於傳輸狀態)。

Description

HC-12 wireless serial port communication module is a new-generation multichannel embedded wireless data transmission module. Its wireless working frequency band is 433.4-473.0MHz, multiple channels can be set, with the stepping of 400 KHz, and there are totally 100 channels. The maximum transmitting power of module is 100mW (20dBm), the receiving sensitivity is -117dBm at baud rate of 5,000bps in the air, and the communication distance is 1,000m in open space. 

The module is encapsulated with stamp hole, can adopt patch welding, and its dimension is 27.8mm×14.4mm×4mm (including antenna cap, excluding spring antenna), so it is very convenient for customers to go into application system. There is a PCB antenna pedestal ANT1 on the module, and user can use external antenna of 433M frequency band through coaxial cable; there is also an antenna solder eye ANT2 in the module, and it is convenient for user to weld spring antenna. User could select one of these antennas according to use requirements. 

There is MCU inside the module, and user don’t need to program the module separately, and all transparent transmission mode is only responsible for receiving and sending serial port data, so it is convenient to use. The module adopts multiple serial port transparent transmission modes, and user could select them by AT command according to use requirements. The average working current of three modes FU1, FU2 and FU3 in idle state is 80μa, 3.6mA an 16mA respectively, and the maximum working current is 100mA (in transmitting state).
