  •  -38% Motor Control Development Bundle - Elektor

    Elektor Bundles Motor Control Development Bundle

    Electric motors are found in countless electronic appliances and devices in and around our homes. In these devices, motor controllers are used to ensure efficient, safe, and accurate ways to govern the speed or the actuator position of the motor(s) used. Electric motors can be classified as either DC or AC depending on the type of voltage used to control them. DC motors are the oldest type of electric motors and they are widely used by electronics developers both in home labs and in schools and laboratories. Almost all printers, cameras, robots, and CNC machines in consumer, commercial, and industrial applications use some kind of DC motor. AC motors on the other hand are used in many home appliances and tools as they can be powered directly from an AC power outlet. Cytron’s Maker Pi RP2040 Development Board is an advanced system based on the RP2040 processor and developed with motor control applications in mind. The board comes with dual-channel brushed DC motor controller hardware, 4 servo motor ports, and 7 Grove-compatible I/O ports, making it an ideal platform within mobile robotics applications, for robot arm control, or in any other type of application requiring precise control of motors and actuators.

  • MicroPython for Microcontrollers - Elektor

    Elektor Publishing MicroPython for Microcontrollers

    Projects with Thonny-IDE, uPyCraft-IDE, and ESP32The 'Python' programming language has enjoyed an enormous upswing in recent years. Not least, various single-board systems such as the Raspberry Pi have contributed to its popularity. But Python has also found widespread use in other fields, such as artificial intelligence (AI) or machine learning (ML). It is obvious, therefore, to use Python or the 'MicroPython' variant for use in SoCs (Systems on Chip) as well.Powerful controllers such as the ESP32 from Espressif Systems offer excellent performance as well as Wi-Fi and Bluetooth functionality at an affordable price. With these features, the Maker scene has been taken by storm. Compared to other controllers, the ESP32 has a significantly larger flash and SRAM memory, as well as a much higher CPU speed. Due to these characteristics, the chip is not only suitable for classic C applications, but also for programming with MicroPython.This book introduces the application of modern one-chip systems. In addition to the technical background, the focus is on MicroPython itself. After the introduction to the language, the programming skills learned are immediately put into practice. The individual projects are suitable for use in the laboratory as well as for everyday applications. So, in addition to the actual learning effect, the focus is also on the joy of building complete and useful devices. By using laboratory breadboards, circuits of all kinds can be realized with little effort, turning the testing and debugging of the 100% homebrew projects into an instructive pleasure.The various applications, such as weather stations, digital voltmeters, ultrasound range finders, RFID card readers or function generators, make the projects presented ideally suited for practical courses or subject and study work in the natural sciences, or in science and technology classes.

  • Raspberry Pi Debug Probe - Elektor

    Raspberry Pi Foundation Raspberry Pi Debug Probe

    The Raspberry Pi Debug Probe is an all-in-one USB-to-debug kit that provides all the necessary hardware and cables for easy, solderless, plug-and-play debugging. It features both a processor serial debug interface (by default the ARM Serial Wire Debug interface, but other interfaces can be supported) and an industry-standard UART interface. Both interfaces use the Raspberry Pi 3-pin debug connector. It is designed to make it easy to debug and program Raspberry Pi Pico and RP2040 with a range of host platforms including Windows, Mac, and typical Linux computers. While designed for use with Raspberry Pi products, the Debug Probe provides standard UART and CMSIS-DAP interfaces over USB, so it can also be used with other processors, or even just as a USB-to-UART cable. It works with OpenOCD and other tools that support CMSIS-DAP. The Debug Probe is based on Raspberry Pi Pico hardware and runs the open source Raspberry Pi Pico Probe software. The firmware is updated in the same way as Raspberry Pi Pico firmware, so it is easy to keep the unit up to date with the latest firmware, or to use custom firmware. Features USB to ARM Serial Wire Debug (SWD) port USB to UART bridge Compatible with the CMSIS-DAP standard Works with OpenOCD and other tools supporting CMSIS-DAP Open source, easily upgradeable firmware Specifications Dimensions: 22 x 32 mm Nominal I/O voltage: 3.3 V Operating temperature: -20°C to +70°C Included 1x Raspberry Pi Debug Probe 1x Plastic case 1x USB cable 3x Debug cables 3-pin JST connector to 3-pin JST connector cable 3-pin JST connector to 0.1-inch header (female) 3-pin JST connector to 0.1-inch header (male) Downloads Datasheet 3-pin Debug Connector Schematics Diagram Latest Firmware
