MIKROE-235

Manual LIN All Mikroelektronikas development systems feature a large number of peripheral modules expanding microcontrollers range of application and making the process of program testing easier. In addition to these modules, it is also possible to use numerous additional modules linked to the development system through the I/O port connectors. Some of these additional modules can operate as stand-alone devices without being connected to the microcontroller. MikroElektronika Additional boardLIN The LIN additional board is used to connect a development system to LIN (Local Interconnect Network). The LIN is used in automotive industry and is composed of one master and up to 16 slave devices. Key features: - Supports baud rates up to 20 Kbaud - Interface to standard USARTs - Output voltage of 5V with 5% tolerances over temperature range - Wide supply voltage, 6.0 18.0V. Figure 1: LIN additional board How to connect the board The LIN additional board can be easily connected to a development system via an IDC10 connector on the additional board and one of the development systems ports. The power supply voltage (VBAT) of 6 to 18V DC is supplied via a screw terminal CN4. The additional board can regulate the power supply voltage and decrease it to 5V. This voltage can be used to power a device via a screw terminal CN3, where the maximum current consumed by the device should not exceed 50mA. The additional board is easily connected to devices sharing LIN via a screw terminal CN2. Depending on the development system in use, it is necessary to set the appropriate switch on the DIP switch SW1 to the ON position, table 1.
