Feature: 1. Compared with traditional development methods, the speed of developing product prototypes is faster, the program is easier to achieve modularity, and maintenance is more convenient 2. More suitable for beginners. Does not require complicated settings, installation of special software and additional hardware, or compilation and downloading. Only needs a USB cable and can be programmed using any text editor 3. Most of the hardware functions can be driven by a single command, and can be developed quickly without understanding the underlying hardware. Very good for product prototyping and software migration, making the development process easy and full of fun 4. The 4 LEDs on the for pyboard, the USR button, the reset button and the BOOTO button, can indicate and use to interact with the system 5. The product is a program development learning tool for makers, DIY enthusiasts, and engineers Specification: Item Type: Core Board Module Material: PCB Purpose: Maker, DIY enthusiast, engineer program development learning tool Input Voltage: 3.6-6V (recommended to use the USB interface for power supply, when power is supplied through the USB interface, it is 5V) Output: 3.3V, maximum current 250mA Writing Language: For python3.
