Pin description
G:Ground wire (GND) — Connect to GND of STC microcontroller
O:Power supply (OUT VCC) — Connect to VCC of STC microcontroller
R:Receive (RXD) — Connect P3.1 of STC MCU
T:Send (TXD) — Connect P3.0 of STC MCU
XD:Sender, generally expressed as its own sender, normal communication must be connected to the RXD of another device.
RXD:The receiving end, generally expressed as its own receiving end, normal communication must be connected to the TXD of another device.
During normal communication, its own TXD is always connected to the RXD of the device!
Self-receiving and spontaneous:RXD is connected to the TXD of other devices during normal communication, so if you want to receive the data sent by yourself, as the name implies, that is, you receive the data sent by yourself, that is, your own TXD is directly connected to RXD, used to test its own transmission and reception Whether it is normal is the fastest and easiest test method. When a problem occurs, the test is first performed to determine whether the product is faulty. Also called loopback test.
Level Logic
TTL level:Usually the data is expressed in binary, which specifies that + 5V is equivalent to logic inch1inch, and 0V is equivalent to logic inch0inch.
RS232 level:-12V to -3V, equivalent to logic inch0inch, + 3V to + 12V logic level, equivalent to logic inch1inch, negative logic
Package Included
5 x USB To TTL Module
5 x Digital Cable
