+ST Nucleo C092RC
+================
+
+The Nucleo C092RC is a member of the Nucleo-64 board family.
+
+CANFD not supported yet.
+
+Buttons
+=======
+
+B1 USER: the user button is connected to the I/O PC13 of the STM32
+microcontroller.
+
+Serial Console
+==============
+
+At default USART2 connected to "Virtual COM Port" is used as serial console.
+
+Configurations
+==============
+
+jumbo
+-----
+
+This configuration enables many Apache NuttX features.  This is
+mostly to help provide additional code coverage in CI, but also
+allows for a users to see a wide range of features that are
+supported by the OS.
+
+Enabled features:
+
+- NSH
+
+- ADC with DMA enabled using A0 and A1 pins
+
+- button with software debouncing enabled (no RC filter on the board)
