Description

Home Arduino Module Sensor Chips About Us - Frequency Range: 134~174MHz - Tx/Rx frequency independent - Channel space: 12.5KHz - Configurable multi-channels - Sensitivity: -122dBm - Output power: +27/30dBm - CTCSS / CDCSS codes - 8 volume levels - 8 squelch levels - UART interface - Temperature: -20°C ~+70°C - TX current: 450/750mA - Supply voltage: 3.3~4.5V DRA818V is a type of compact wireless voice transceiver module based on RFIC RDA1846 and works in VHF band. It integrates high speed microcontroller, high performance wireless transceiver IC, high power PA, audio process and squelching circuits. It provides standard UART interface which users can easily configure appropriate parameters for different applications. Users can easily construct a walkie-talkie system by connecting microphone, audio PA and speaker. Some parameters of DRA818V modules can be changed by following the commands in this section, which provide flexibility for designers to optimize related parameters to achieve the best performance. DRA818V modules use standard UART interface to communicate with microcontrollers or other hosts. The default data format is: 8 data bits, 1 stop bit, no parity and 9600 kbps data rate. DRA818V and DRA818U are based on RDA1846. Comparing to DRA808M based on RDA1845, CDCSS and audio control AT command are added, which provides more flexibility for the users who need to process audio signal more precisely. DRA818V is the VHF band version of DRA818U. From the field testing results, the RFIC on module should automatically filter the frequencies below 300Hz no mater Highpass filter is enabled or not so please pay attention to it if the applications need low frequencies. Package includes: 1PCS 144MHz 145MHz 146MHz 154MHz 174MHz VHF HAM Radio Module Amateur Radio DRA818V Payment Shipping Refund Payment Customer satisfaction is our top goal.
