【ST NUCLEO-G071RB Review】_01_First impression [Copy link]

The development board ST NUCLEO-G071RB evaluated in this event is provided by STMicroelectronics. Thanks to STMicroelectronics for supporting EEWorld's evaluation! In December 2018, I had the honor to participate in the evaluation activity of ST NUCLEO-G071RB, a development board jointly provided by EEwolrd and STMicroelectronics. First of all, I would like to thank EEWorld for providing this evaluation opportunity, as well as ST for providing the development board, software and hardware related development materials for this event, which provided great support for this evaluation! I have used various series of STM32 MCUs in the field of embedded development and design, such as STM32F051, STM32F103, STM32F429... Usually I design the circuits myself, but I have very few official Nucleo development boards.

• First sight

This NUCLEO-G071RB development board is the second board I have. It’s our first meeting. Let me show you some unboxing pictures to get to know this new member:

Simple user manual:

[p=30, null, left left]A brief description of the development board resources, including the core, operating frequency, memory, Flash capacity, expansion interface and other information used by the development board:

Main control chip STM32G071RBT6:

At first glance after unboxing, what catches your eye is the familiar plastic packaging, the same appearance design, including the shape of the circuit board and the interface are very familiar, very similar to the NUCLEO-F411RE in your hand.

• Progress

The left one is the new product in this review, NUCLEO-G071RB, and the right one is NUCLEO-F411RE. The overall design is very similar, but from the details, there are still some differences between the new and old products, which is also a reflection of the progress in design.

The size of the crystal oscillator has been reduced overall, and the main crystal oscillator uses a 3215 package, which is also an improvement:

The USB interface has been upgraded to a Micro interface, which is a more down-to-earth upgrade:

The upgraded onboard ST-LINK has reduced the size of the device overall:

• Onboard resources

A simple comparison of the two development boards shows that the two development boards actually have roughly the same onboard resources:

●1 user LED, shared with Arduino●1 user and 1 reset buttons●Board expansion connector: Arduino Uno V3 ST Morpho expansion header for full access to all STM32 I/Os●Onboard ST-LINK/V2-1 debugger/programmer: Virtual COM port SW debug port

[p=32, For details about the development board resources, please visit the NUCLEO-G071RB official website. First, you need to have a suitable development platform. You can choose Keil MDK-ARM for development, or use IAR EWARM for development, or other IDEs based on GCC. Starting from the next evaluation, all projects will use Keil as the main development environment. To be continued... This content is originally created by EEWORLD forum user lvxinn2006.
