NUCLEO-G071RB
In December, 2018, STMicro announced their STM32G0 - value line of microcontrollers. https://blog.st.com/stm32g0-mainstream-90-nm-mcu/
The NUCLEO-G071RB is STMicro's low cost development board for the STM32G071RB processor. This board is often used as a training tool for the STM32G0 series devices.

Everything compiled and built well. Had a problem downloading: "Flash Download failed - Cortex - M0" The issue is the lack of a programming method defined. Project -> Options for Target xxx (Alt F7) -> Debug tab -> Use ST-Link Debugger -> Settings -> Flash Download -> Add the STM32G0xx 32KB Flash algorithm with Address Range 080000000H - 08007FFFH.
The green LED, LD2, annode, connects to PA12, pin6, on the STM32G0 part. (Driving this pin high turns the LED on.) The blue push-button, B1, connects T_NRST, pin 4 of the STM32G0 part, to ground when pressed. (I'm guessing the T_NRST signal is re-assigned as a GPIO for this function.)
