MicroSD Card Slot
4. MicroSD Card Slot
BRD4320A contains a microSD card slot which is connected to the Wizard Gecko WGM110 Wi-Fi Module. It enables testing of SW
applications utilizing a microSD or microSDHC card. The memory card can be accessed from the host processor using BGAPI commands, BGScript commands or by using the internal HTTP Server of the Module.
Note: The microSD card slot is located on the bottom side of the BRD4320A Radio Board. To install a microSD or microSDHC card
remove the Radio Board from the WSTK Mainboard and push the microSD or microSDHC card into the card slot with the metal contacts of the memory card facing towards the PCB and attach the Radio Board back into WSTK Mainboard connectors.
CHARACTERISTICS
Supported file systems: FAT 16 and FAT 32
Maximum memory size: 32 GB.
Supported memory card types: microSD and microSDHC.
Programming related information
The microSD card slot is connected to USART1 Location 1 of the WGM110 Module and the Chip Select to Port D Bit 7.
GPIO pinout, interfaces and alternative locations are described in the WGM110 Wi-Fi Module Data Sheet, hardware configuration in the
UG161: WGM110 Wi-Fi Module Configuration User's Guide and related commands in detail in the WGM110 API Reference Manual.

USB Connector
5. USB Connector
BRD4320A contains a micro USB connector which is connected directly to the Wizard Gecko WGM110 Wi-Fi Module's USB port. This
USB connector may be used in SW application tests as an interface between the Module and external devices such as a PC and/or
simply to provide power to the Module. This is a useful feature since it allows the Module to be powered externally while the WSTK
main board can be switched completely off.
The radio board contains a voltage regulator and a transisor switch that automatically connects the regulated supply to the module power supply. The power select slide switch on the WSTK Mainboard should be set to USB or BAT to avoid conflict with the Mainboard
power supply when using the USB connector.
Note: Software configuration details for using the USB connector of the Radio Board are described in the "UG161: WGM110 Wi-Fi
Module Configuration User's Guide".

Supported USB standards: USB Full Speed
USB connector type: micro USB (female)
Maximum data transfer speed: 12 Mb/s.
