51 MCU kudhibiti stereo FM transmitter kufanya BH1415F
Description: 1, kudhibiti kwa kutumia MCS51, kwa kutumia ndogo mfumo wa maombi ya kubuni, mzunguko nje ni rahisi sana! 16 kifungo kubuni, unaweza kudhibiti 80.0 ~ 109.9MHz frequency mbalimbali;
2,4 tarakimu anode ya kawaida ya kuonyesha LED frequency;
Features: 1, inaweza kuweka kujitegemea mia moja, kumi, kidogo, mzunguko wa hatua decimal;
2, kupeleka frequency presets;
3, udhibiti wa mono / Stereo; bendi stereo transmitter maelekezo;
