The next figure shows the recommended schematics for connecting WGM110 Module with an external host over USB.
Figure 3.3. Connecting the WGM110 Module with an External Host using the USB Interface
Note: When using the USB interface, the VBUS signal should be connected to the USB host's VBUS line.
Note: If the VBUS line is not available on the host, the module's VBUS signal should be connected to the VDDCPU.
Note: If the USB is not used at all, the VBUS signal should be connected to the VDDCPU.
3.2 Peripheral Interfaces and Functions
There are several different types of peripheral interface connections available on the WGM110 Module. External sensors and peripheral
chips can be connected using the USART (UART/SPI) and I2C interfaces. In addition to the above mentioned connections, WGM110
includes two timers for PWM applications, an 8-channel 12-bit ADC converter and a real time counter.
