Mikrobus™ Socket - Infineon XMC4800 IoT Amazon FreeRTOS Connectivity kit Manual

XMC4800 IoT Amazon FreeRTOS Connectivity kit WiFi with EtherCAT® Kit
For XMC4000 family
Hardware description
2.3 mikroBUS™ socket
This kit includes the WiFi module mikroBUS™ from MikroElektronica based on ESP-WROOM-02 device. More
Information about this module can be found in the link:
The mapping of GPIOs and XMC™ pin functions to mikroBUS™ functions can be found in Table 5. The mikroBUS™
connector supports
SPI interface with one chip select (SPI_xxx)
I2C interface (I2C_xxx)
•
UART interface (UART_xxx)
•
PWM signal output (PWM)
•
ADC input (ADC)
•
Interrupt input (INT)
•
Reset (RST)
•
•
Attention: Jumper JP300 (IOREF) must be set to 3.3 V (VDD3.3) when using click™ boards. 5 V click™ boards cannot be
used with the XMC4300 Relax EtherCAT® Kit.
Note:
The mikroBUS™ UART and debugger's UART shares the same USIC channel (U1C0) of the XMC4800 device, but do
not share the same pins. Parallel operation by time multiplexing is possible.
