SA858 is a professional  4W / UHF band walkie talkie module. Strong RF circuit, DSP, digitalinterface, and audio amplifier is built in. Besides Uart command, user can use our provided PCsoftware to configure all the parameters. The parameters includes: Tx frequency, Rx-frequency, TxCTCSS /CDCSS, Rx CTCSS/CDCSS , digital volume and SQ. To avoid the heating for this highpower walkie talkie, we have done special handling on the software with a strong heat sink added,which makes it has no problem for long time continuous working.When SA858 is connected with SA858-PJ, it is easy to organize a professional all in one walkietalkie system, the system include 16 predefined frequency channels, adjustable volume, configurableCTCSS/CDCSS. User need only to connect with power supply and speaker.Simplified interface and ultra small size make SA858 widely used in various applications andconveniently embedded into various handheld devices.

Accessories:
1)Antenna:
Antenna is an important part in communication system. Its performance will influence the whole communication system. This module requires antennas impedance in 50oHm.
2)Accessory board:
To make it convenient to use, we have an accessory board SA858-PJ which can be used with SA858 walkie talkie module,the small board extend the pins of the module by the special FPC.
 3)Heat sink:
This walkie talkie module is a high power wireless device,it will has bigger current during transmitting,so we have equipped module with a specialized heat sink.
