When getting started with microcontrollers, you can consider choosing Arduino series or STM32 series microcontrollers:

1. Arduino series : Arduino is an easy-to-use development platform suitable for beginners. Arduino Uno is one of the most classic models, with rich information and community support, suitable for rapid learning and prototype development. Arduino also has other models, such as Arduino Mega, Arduino Nano, etc., which can be selected according to project requirements.

2. STM32 series : STM32 is a low-cost, high-performance 32-bit microcontroller series launched by STMicroelectronics, with rich peripheral interfaces and powerful performance. The STM32 series microcontroller is suitable for advanced learning and is used to develop more complex projects such as embedded systems, IoT devices, etc.

Both microcontrollers have a wide range of applications and rich data support. You can choose the appropriate model for learning and practice according to your personal interests, project requirements and learning goals. The Arduino series is suitable for quick start and prototype development, while the STM32 series is suitable for advanced learning and development of more complex projects.
