Chapter 3 hardware interface
3.1
PC interface (board marked:
J1)
Whether you order UART or USB interface type (board hardware circuit factory settings different, do not mix),
PCB, module and user equipment interfaces with a single row socket / pin (split core 2.0 spacing, integrated
4-core 1.27 pitch).
The user no special requirements, provide the user interface lead length is 150mm.
3.1.1
serial communication
Serial communication module with user devices, the interface the J1 pin is defined as follows:
The pin No. Name Type
Functional Description
1
Vin
in
Power is input. (Line color: red)
2
TD
out
Serial data output. TTL logic levels. (Line color: green)
3
RD
in
Serial data input. TTL logic levels. (Line color: white)
4
GND
- Signal ground. The internal power supply connected. (Line color: black)
5
NC
- Undefined, vacant. (Integrated module no such pin)
Note: the Type column in the input to the module out from the module output.
3.1.1.1 hardware connection
The Newsletter: module via a serial communication interface, can be directly related to a 3.3V or 5V power microcontroller module data
Send foot (pin 2 TD) connected to the bit data reception end (RXD) the module data reception feet (3 feet RD) connected to the data bit machine
Sender (TXD).
For RS-232 level (for example: PC machine) the host computer to communicate between the module and the host computer to increase the level of turn
The conversion circuit (for example: MAX232 circuit).
