Arduino UNO click shield
The Arduino UNO click is an extension to the Arduino UNO R3 headers. It’s a simple shield that converts Arduino UNO R3 headers to two mikroBUS host sockets that allow you to connect many other click shields to your board. In other words, the Arduino UNO click will generally be used by other shields using the mikroBUS interface.
Two mikroBUS headers are exposed by the overlay:
mikrobus_header_2, each corresponding to a socket on the Arduino UNO
The first socket (
mikrobus_header_1) is the default socket which is
assigned the node label
mikrobus_header in the overlay.
This shield can only be used with a board which provides a configuration for Arduino R3 connector.
The board must also define node aliases for arduino Serial, SPI and I2C interfaces (see Shields for more details).
Connecting shields should use the first socket (
socket is assigned the
mikrobus_header node label.
-DSHIELD=arduino_uno_click when you invoke
west build with
other mikroBUS shields. For example:
# From the root of the zephyr repository
west build -b sam_v71_xult samples/net/sockets/echo_server -- -DSHIELD="arduino_uno_click atmel_rf2xx_mikrobus" -DOVERLAY_CONFIG=overlay-802154.conf
