================
ST Nucleo U083RC
================
.. tags:: chip:stm32, chip:stm32u0, chip:stm32u083
The Nucleo U083RC is a member of the Nucleo-64 board family.
USB 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
==============
nsh
---
Configures the NuttShell (nsh) located at apps/examples/nsh. The
Configuration enables the serial interfaces on USART2. Support for
builtin applications is disabled.
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 with builtin applications
- OS test (ostest)
- ADC with DMA enabled using A0-A3 pins
- PWM on TIM1 CH1 (PA8, D7)
- Quadrature encoder on TIM3 (PA6/PA7, D12/D11)
- Timer driver on TIM6 (/dev/timer0)
- IWDG and WWDG watchdogs
- button with software debouncing enabled (no RC filter on the board)
