Package:

1PCS / 5 PCS TTL_UART to LIN Bus Module(Upgraded version)

1.Description:

It is a TTL_UART to LIN bus module.The module uses TJA1021 IC.It is mainly used for communication monitoring and maintenance of LIN bus equipment.

2.Feature:

1 Pure data signal conversion

2 Its data is stable

3 It has a green power indicator that shows the working status.

4 It can monitor and maintain LIN bus device communication.

3.Description:

1 Product Name:TTL_UART to LIN Bus Module

2 Product Chip:TJA1021

(Has been changed to fully compatible and more stable performance SIT1021T)

3 Working Voltage:DC 12V/24V

4 Work Temperature:-25℃~85℃

5 Work Humidity:5%~95%RH

6 Size:43*20*12mm

7 Weight : 7.3g

4.Specific Function Introduction:

1、 The measured baud rate of the module can reach 57600bps,and the recommended maximum operating frequency is less than 20Kbps.

2 、This module is just a level conversion module and does not participate in conversion analysis such as software protocols.

3、 When the module is connected to the computer's COM port,the computer can receive data,but it cannot communicate with your slave device as a host.The computer's com port cannot generate the 13-bit start bit in the LIN protocol,but it can be connected to a development board such as a microcontroller.

4、 Power supply anti-reverse connection protection, LIN bus anti-surge protection

5 、Compatible with 3.3V/5V microcontroller system

Pin description:

VIN: Power supply positive pole (DC 12V/24V)

INH:Used in host mode (please refer to the TJA1021 PDF)

LIN :LIN BUS

GND: Power supply negative pole

TX :TTL serial port data output

SLP :Sleep

RX : TTL serial port data input

GND:Ground wire(Connected to MCU)
