SP3232E的功能是什么

2，可以和单片机相连的蓝牙串口模块能不能直接连在电脑的串口上使用

可以的，需要个SP3232这样的芯片，蓝牙模块你可以看看BF10,用得很广的，资料也很全。

电脑的串口是标准RS232 串口单片机串口是 TTL 电平的做相应的电平转换后可以连接，如使用max232

可以和单片机相连的蓝牙串口模块能不能直接连在电脑的串口上使用

3，SP3232是什么芯片啊其功能与作用是什么啊

用在RS232通信上的，TTL电平与232电平的相互转化

这个和max232是一样的ttl转rs232的，只不过sp3232是3.3v供电的而已。c1+，c1-之间并一个电容。 c2+ ，c2-之间并一个电容。v+与电源之间并一个电容。v-与地之间并一个电容。

SP3232是什么芯片啊其功能与作用是什么啊

4，SP3232可以通讯多少米

SP3232是232电平的通讯接口芯片吗？232发送电平与接收电平的差仅为2V至3V左右，共模抑制能力差，其传送距离最大为约15米，最高速率为20Kbps。

单片机的串口必须经过电平转换才可以和标准rs-232通信，这个转换芯片5v的一般是max232或sp232，3.3v的一般是max3232或sp3232。
