You know, although the foreign barberry Zero is known as only a few dollars, but it has a lot of money to buy in China. Even if you know that Taobao is about 1,70RMB, it is the price of the trees. Raspberry zero also needs a lot of extra peripheral modules and cables are really easy to use. Therefore, for the Chinese people, the banana sent ZERO still has a significant price advantage. Of course, because the board itself has a space limit, there is a place that makes the author are not very satisfied. For example, there is no SATA interface, the onboard MINIHDMI is somewhat embarrassing, no standard With antenna, if it can improve, it will be better. Pyboard (evaluation) Property: Micropython Single to say Pyboard, you may not be very clear, but say Micropython, I believe many of the engineers are bright. Micropython is scaled in Python, which is a month-spending month-based, based on ANSI C (C language standard), and then follows Python's specification in grammar, mainly in embedded hardware (here The specific microcontroller level is easier to implement the operation of the underlying. As of now, many embedded hardware have successfully transplanted micropython, such as Pyboard, ESP8266, WIPY, ESPRUINO PICO, STM32F4 Discovery, etc. In this, I want to say Micropython's true love, that is Pyboard, after all, this board is also from the Damien George. Pyboard is very small, only 40mm * 33mm, portability is OK. Pyboard Based on the STM32F405RG microcontroller, Pyboard is powered by the onboard MicroSB interface and data transmission. The onboard peripheral includes a MicroSD card interface, 4 LED lights, two mechanical buttons, an acceleration sensor, clock module, others The signal is set through the metal via holes on the plate. The user can easily implement the control of the microcontroller through micropython, most intuitive, you don't need to be complicated, you can use the micropyton scripting language to operate through the micropyton scripting language, which allows more computer beginners to do hardware DIY, users can implement access and control of hardware underlying through the micropython language, such as controlling LED bulbs, LCD displays, read voltages, control motors, access SD cards, etc. For the development of the microcontroller, it is generally rarely involved in the development of the upper level, many of which are collecting data, doing control, etc. C / C ++ does not have a more concise development method. So, in synthesis, for Micropython, individuals expressed recognition, which brought more efficient development for the majority of electronic enthusiasts, which can be applied to DIY in life.
