UMB Board
Universal microcontroller with 24 GPIOs

Universally usable
24 GPIOs
ADC with 10 bits
I²C, SPI and 2 x UART
Colour sensor retrieval

Description

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.

Applications

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.
Control of up to 4 relay modules via I²C.
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.
