Maker Line is a line sensor with 5 x IR sensors array that is able to track line from 13 mm to 30 mm width. The sensor calibration is also simplified. There is no need to adjust the potentiometer for each IR sensor. You just have to press the calibrate button for 2 seconds to enter calibration mode. Afterwards you need to sweep the sensors array across the line, press the button again and you are good to go. The calibration data is saved in EEPROM and it will stay intact even if the sensor has been powered off. Thus, calibration only needs to be carried out once unless the sensor height, line color or background color has changed. Maker Line also supports dual outputs: 5 x digital outputs for the state of each sensor independently, which is similar to conventional IR sensor, but you get the benefit of easy calibration, and also one analog output, where its voltage represents the line position. Analog output also offers higher resolution compared to individual digital outputs. This is especially useful when high accuracy is required while building a line following robot with PID control. Features Operating Voltage: DC 3.3 V and 5 V compatible (with reverse polarity protection) Recommended Line Width: 13 mm to 30 mm Selectable line color (light or dark) Sensing Distance (Height): 4 mm to 40 mm (Vcc = 5 V, Black line on white surface) Sensor Refresh Rate: 200 Hz Easy calibration process Dual Output Types: 5 x digital outputs represent each IR sensor state, 1 x analog output represents line position. Support wide range of controllers such as Arduino, Raspberry Pi etc. Documentation Datasheet Tutorial: Building A Low-Cost Line Following Robot

The Maker pHAT is the solution to the most common problems beginners face starting with Raspberry PI. Its intelligent and simple design makes it easy to attach to your Pi, and it helps you avoid all the tedious work of connection various other accessories. Additionally, the LEDs corresponding to each pin makes it extremely easy to see where a potential problem lies The Maker pHat has the same size as the Raspberry Pi Zero with all 4mounting holes aligned. However, it can be used with Raspberry Pi 3B, 3B+ and 3A+, by inserting a 2 x 20 stacking header. Features Raspberry Pi Zero size, stack perfectly on to Raspberry Pi Zero Compatible with standard size Raspberry Pi 3B / 3B+, medium size Raspberry Pi 3A+ and smaller size Raspberry Pi Zero / W / WH. Standard Raspberry Pi GPIO footprint. LED array for selected GPIO pins (GPIO 17, 18, 27, 22, 25, 12, 13, 19). 3x on board programmable push buttons (GPIO 21, 19 and 20, need to configure as input pull up). Onboard active buzzer (GPIO 26). Proper labels for all GPIOs, including SPI, UART, I2C, 5V, 3.3V, and GND. Utilize USB Micro-B socket for 5V input and USB to UART communication.

Cytron Maker Pi RP2040 features the first microcontroller designed by Raspberry Pi – RP2040, embedded on a robot controller board. This board comes with dual channel DC motor driver, 4 servo motor ports and 7 Grove I/O connectors, ready for your next DIY robot / motion control project. Now you can build robot, while trying out the new RP2040 chip. The DC motor driver onboard is able to control 2x brushed DC motors or 1x bipolar/unipolar stepper motor rated from 3.6 V to 6 V, providing up to 1 A current per channel continuously. The built-in Quick Test buttons and motor output LEDs allow functional test of the motor driver in a quick and convenient way, without the need of writing any code. Vmotor for both DC and servo motors depends on the input voltage supplied to the board. Maker Pi RP2040 features all the goodness of Cytron's Maker series products. It too has lots of LEDs useful for troubleshooting (& visual effects), is able to make quite some noise with the onboard piezo buzzer and comes with push buttons ready to detect your touch. There are three ways to supply power to the Maker Pi RP2040 – via USB (5 V) socket, with a single cell LiPo/Li-Ion battery or through the VIN (3.6-6 V) terminals. However only one power source is needed to power up both controller board and motors at a time. Power supply from all these power sources can all be controlled with the power on/off switch onboard. Cytron Maker Pi RP2040 is basically the Raspberry Pi Pico + Maker series' goodness + Robot controller & other useful features. Therefore this board is compatible with the existing Pico ecosystem. Software, firmware, libraries and resources that are developed for Pico should work seamlessly with Cytron Maker Pi RP2040 too. CircuitPython is preloaded on the Maker Pi RP2040 and it runs a simple demo program right out-of-the-box. Connect it to your computer via USB micro cable and turn it on, you will be greeted by a melody tune and LEDs running light. Press GP20 and GP21 push buttons to toggle the LEDs on/off, while controlling any DC and servo motors connected to it to move and stop. With this demo code, you get to test the board the moment you receive it! While connected to your computer, a new CIRCUITPY drive appears. Explore and edit the demo code (code.py & lib folder) with any code editor you like, save any changes to the drive and you shall see it in action in no time. That's why we embrace CircuitPython – it's very easy to get started. Wish to use other programming lauguages? Sure, you are free to use MicroPython and C/C++ for Pico/RP2040.
