BBC micro:bit - a combination of tradition and modernity
The BBC micro:bit board is an amazing tool for learning programming and creating your first simplest embedded projects, which can also work with other embedded boards with a much higher computing power, such as Raspberry Pi 4B, and even more - even for new users more user-friendly than Arduino. The roots of micro:bit plates date back to the 1980s. The name comes from the 8-bit BBC Micro computer designed by Acorn Computers, mainly for educational purposes with a view to learning how to program electronic digital machines. The BBC micro: bit platform continues the legacy of the BBC Microcomputer, but instead of the MOS 6502 chip, it uses an NXP processor, designed in the ARM architecture on the Cortex-M0 core, which, like the AVRs in most Arduino boards - works at 16MHz and has a built-in memory 256kB FLASH memory and 16kB RAM memory. At the user's disposal, the board has a Bluetooth module, USB connector, 5x5 LED matrix, as well as an accelerometer, magnetometer and two programmable tact switch buttons. The board can be powered via a USB port from a computer or battery pack, which is practical especially in wireless applications, e.g. in remote-controlled vehicles.
BBC micro:bit Go - amazing starter kit for electronics projects creating
BBC micro: bit is a small development platform that has been designed for beginners in the field of programming and electronics. In this way, designers have created a practical tool that is proof that electronic devices are not only entertainment products. The goal of the micro:bit project is to prove that learning electronics can be a very interesting activity, and programming does not have to be difficult. Therefore, the whole board has been prepared so that it can be used to implement many interesting projects (such as an electronic dice, wristwatch, or a simple arcade game). The board's software is delivered with an intuitive mobile application that allows wireless programming of the board via Bluetooth, thus obtaining greater possibilities of interaction with the BBC micro: bit platform at a higher level of access. The micro: bit Go set includes all the necessary components needed to run the micro: bit platform. The kit includes a micro: bit development board, a USB to micro USB connection cable, a battery container with a power cord and two AAA batteries. In the box, you will also find a user's manual that depicts four interesting project ideas that will allow you to start the adventure with micro:bit! Two programmable buttons will be a good foundation for a simple game console or volume control. You can use the 5x5 LED matrix as a light sensor, as well as a display on which you can present simple and creative animations, as well as alphanumeric characters. The surface of the other side of the board is occupied by an accelerometer, compass and Bluetooth module. The micro USB connector with a dedicated microcontroller is responsible for the communication of the board with the computer and power supply. An alternative option is to connect the battery power supply via the 2-pin JST connector. On the edge of the board there are 20 gold-plated flat connectors and 5 gold-plated ring connectors with a diameter of 4mm - for connecting auxiliary supply voltage, ground and three input/output connectors, which, depending on the application, can be programmed as analog or digital, enabling cooperation with peripheral devices, such as e.g. motor controllers or measuring sensors. The external equipment is connected to the ring connectors of the BBC micro: bit board via "banana" or "crocodile" wires, thus enabling rapid prototyping.
