The UMB2 board was developed to provide the basis for various applications. The GPIOs of the controller have a logic level of 3.3 V and are tolerant up to 24 V. 8 of the pins can be used as analogue inputs. The UART0 of the controller communicates with the WinGuard software on the test PC via a RS-422 level converter. Corresponding WinGuard script commands are available for using the I2C, SPI or UART2 interfaces.
Testing coloured LEDs with VEML6040 colour sensors in conjunction with an I2C multiplexor extension; up to 16 sensors can be connected to one UMB2 board. The WinGuard software contains a corresponding GUI for measuring the brightness and colour.
Testing of components with I2C or SPI connections.
Implementation of customer-specific modifications: 5 male connectors can be installed on the board for inserting a PCB when necessary. This provides users with an easy way to integrate matching circuits etc. into the test system.
