mini walkie talkie module S

M3000 Silver Phoenix is a mini walkie-talkie module developed by MC Devices. Its size is as small as 31.75mm (length)x 20.828mm (width)x 6.5mm (height). A walkie-talkie is made by simply adding external speaker and power. The front side of M3000 Silver Phoenix is control board equipped with MCU, and its back side is M3000 high frequency module. M3000 Silver Phoenix may be easily embedded in a variety of portable devices, and work as walkie-talkies, which are widely used in tourism, hotel service and gifts. The easiest way is to fix a channel directly on the board, and connect a speaker and power. For more complicated application, channels selection and volume regulation may be achieved by simply adding a DIP switch. Main Functions Frequency:: 4-32 frequency points are randomly selected within 315MHz-385MHz or 390MHz-470MHz (occupying 2-5 I/O ports) Power: selected between 0.5W-1W(test voltage: 4.2V) Receiving sensitivity: <-120dBm CTCSS code: 0-8 selectable codes (occupying 0-3 I/O ports) Volume regulation: 2-4 scales may be set by external DIP switch (occupying 1-2 I/O ports), and the default set is the lowest volume. Automatic squelch function TX, RX indicator Sleep mode No jarring sound after PTT call (standard function) Notes:: There are only 5 I/O Ports in Silver Phoenix MCU, so customers should select ports reasonably.
