SA828 is an all-in-one skilled walkie-talkie module in small measurement. It is rather straightforward to make use of with highly effective perform. This module has full perform of knowledgeable walkie-talkie and might speak with any analog walkie-talkie available in the market. With the small measurement, it may be simply embedded into instrument, transportable and handheld gadget. SA828 works effectively within the sizzling/chilly atmosphere with the KDS 1PPM TCXO. The options of fantastic antenna match community, good RF amplifier, excessive RF sensitivity permit its communication simply to attain over 3Km in open space.

Rotary change for channel choice, EEPROM, Audio Amplifier, RF Amplifier, PTT key, Antenna socket are all included in such a small measurement module. Moreover, all parameters (CTCSS, CDCSS, SQ, Predefined channels and so forth) will be simply modified both by PC software program or command utilizing UART interface. With the embedded audio quantity turning circuit, consumer can solely solder a variable resistor on Pin16, Pin17 to regulate the quantity steplessly.

There are two frequency bands of SA828: SA828-U and SA828-V. The one distinction is the frequency vary. The others are identical, together with module measurement, interface, software program protocol, and so forth. The 2 modules’ frequency ranges are:

SA828-U: U band, 400 — 480MHz
SA828-V: V band, 134 — 174MHz
