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
6 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)
