Computer IC Chips Arduino DB9 RS232 to TTL MAX3232 Refresh Module

Details:

 

Product Name: RS232 to TTL board / refresh upgrade board / STC microcontroller programmer / STC microcontroller program downloader

Supply voltage: 3.3V-5.2V wide voltage support power

Serial converter chip: MAX3232

MAX232 module introduces map:

 Output interface definition: VCC / GND / TXD / RXD

  1) VCC: the + external power supply, such as external devices TTL communication ports can provide 3.3V-5.2V power supply, can be connected directly to use. If you use another regulated power supply, set the power of the "+" pole connected to VCC, the power of the "-" pole connected to GND). Do not reversed, otherwise it will burn chip on board;

  2) GND: TTL signals, the use of external devices connected to a TTL signal ground;

3) TXD: 232 side TTL level transmission signal output terminal connected to an external device when using a TTL signal transmission terminal;

4) RXD: 232 side accepts TTL level signal input for connecting external devices when using a TTL signal receiving end;

5) connected microcontroller reference to FIG.

     Product Features: No driver, connection can use, without stealing functionality required from an external 3.3V-5V power supply pins. The power indicator plate.

Usage: MAX232 level converter for STC SCM download DVD / HDD / router / GPS / receiver upgrade.
