• SPI bus interface is connected to a high performance UART bridge, SC16IS740IPW.

The UART interface connects to devices on mikroBUS click connectors.

• SPI bus interface can also connect to the mikroBUS click connectors, J33 and J34,

via level translators.

The following table describes the SPI devices used on the FRWY-LS1012A board.

The FRWY-LS1012A board supports a mikroBUS host connector that consists of two

1x8 female headers J33 and J34. The mikroBUS host connector or socket can be

connected to mikroBUS Click boards™. Click boards are plug and play solutions to add

new functionality to the board design.

The mikroBUS host connector supports following interfaces:

• SPI connectivity from the LS1012A on CS1.

• UART connectivity through the LS1012A SPI to the UART bridge.

• I2C connectivity from the LS1012A.
