mikroBUS™ Notes

Seven provides default interface routing for the mikroBUS™ sockets:

• mikroBUS™ 1 uses uart2 / i2c2 / spi2

• mikroBUS™ 2 uses uart3 / i2c3 / spi3

Application overlays are expected to enable the function they need on the target socket. The generic &mikrobus_* labels target mikroBUS™ 1 by default, while the explicit &mikrobus_1_* and &mikrobus_2_* labels target a specific socket.

On nRF9151, the serial blocks are multiplexed:

• uart1 / i2c1 / spi1

• uart2 / i2c2 / spi2

• uart3 / i2c3 / spi3

Only one function from each group can be enabled at a time, so each mikroBUS™ socket may use UART or I2C or SPI, but not multiple of those functions simultaneously.

The on-board RGB LED uses spi1 with MOSI on P0.18 by default, so serial block 1 is not available for mikroBUS™ overlays unless that LED route is overridden.

For seven/nrf9151/ns, uart1 is disabled by default to match the upstream nrf9151dk non-secure board behavior where TF-M uses it by default.

Examples:

• To place an I2C Click board on mikroBUS™ 1, enable &mikrobus_1_i2c and add the device below it in an app overlay.

• To place an SPI Click board on mikroBUS™ 2, enable &mikrobus_2_spi and add the device below it in an app overlay.

• To place a UART Click board on mikroBUS™ 1, enable &mikrobus_1_serial in an app overlay.

• Upstream shields target mikroBUS™ 1 by default through &mikrobus_spi, &mikrobus_i2c, &mikrobus_serial, and &mikrobus_header.
