SmartElex 10D DC Motor Driver HAT for Raspberry Pi | PWM Driver HAT with PWM Speed Control The SmartElex 10D DC Motor Driver HAT is a compact and reliable expansion board designed specifically for Raspberry Pi to control DC motors with precise speed control. It helps users drive motors directly from the Raspberry Pi without complex wiring or external driver circuits, making motor control simpler and safer. This HAT is ideal for students, makers, educators, and engineers who are building robotics or motion-based projects and want a clean, plug-and-play solution. This motor driver HAT is widely used in robotics, automation systems, and prototyping projects where smooth and controlled motor operation is required. With PWM-based speed control and seamless Raspberry Pi compatibility, it allows easy integration into existing projects and code setups. The stable performance and straightforward design make it suitable for classroom learning, DIY robotics, and early-stage product development where reliable motor control is essential. Hardware Overview Features: Designed specifically as a motor driver HAT for Raspberry Pi PWM-based speed control for smooth motor operation Supports both single-signal and dual-signal motor control modes Simple plug-and-play installation on Raspberry Pi GPIO header Ideal for robotics, automation, and motion control projects Reliable performance suitable for education, prototyping, and DIY builds How to Use The SmartElex 10D DC Motor Driver HAT can be controlled in two different ways depending on your project requirements. Using Two Control Signals (Speed and Direction) In this mode, two separate control signals are used. The PWM signal is applied to the PWM pin to control the motor speed, while the DIR pin is used to control the motor direction. This method offers straightforward and precise control, making it ideal for most robotics and automation applications. Using One Control Signal (Combined Speed and Direction) In this mode, only one control signal is required. The PWM pin is connected to a logic high level, and the DIR pin receives the PWM signal. When the PWM duty cycle is 50%, the motor stops. If the duty cycle is below 50%, the motor rotates in one direction, and if it is above 50%, the motor rotates in the opposite direction. The actual rotation direction depends on the motor wiring

TP4056 Battery Charger C Type Module with Protection The TP4056 1A Li-Ion Battery Charging Board Type C with Current safety is a small module designed for charging single-cell 3.7V lithium-ion batteries, such as 16550s, that do not have their own safety circuit. Using the TP4056 charger IC and the DW01 battery protection IC, this lithium battery charger produces a 1A charging current and will automatically stop charging once completed. Also, if the battery voltage goes below 2.4V, the safety IC will cut off the load to save the cell from functioning at an unacceptably low voltage. The TP4056 charging module also protects against overvoltage and reverse polarity connections, often sacrificing itself to preserve the battery. Just remember to double-check your connections the first time you put it up. Your batteries can be safely and easily charged with TP4056 lithium-ion battery charger. All you need to do is connect it correctly, and it will do the rest. Use the Module Through the Following Steps: To supply power, either plug in a Type C cable or attach a 5V DC source to the IN+ and IN-labeled pads on the module's left side. Fasten the battery that has to be charged to the B+/B- pads on the module's right side. The OUT+/OUT- pads on the right side can also be used to attach a load, or an object that the battery will power. Keep in mind that while the battery is charging, unplug the load. When the charging process is finished, the green LED will turn on, while the red LED will illuminate to signify that the charge is ongoing. Be careful to never charge your battery at a rate exceeding 1C Note: Please remember the following crucial information: The module's 5V input side is the only one to which the ampere meter should be attached. A charging current of around 37% of the battery's capacity is advised. A 400mAh charging current is adequate for a 1000mAh battery. Make use of reasonably thin connecting cables. Verify the security of the connecting point. It is usual for the current to decrease below 1000mA if the input voltage is greater than 5.2V. In order to shield the chip from harm, this protective function immediately lowers the charging current. Reverse polarity should be avoided at all costs. Features It features a modern USB Type-C port that provides convenient and universal power. This module includes integrated protection against over-charge, over-discharge, and short-circuits. It utilizes an intelligent CC/CV algorithm to ensure a fast, safe, and efficient charging cycle. It is equipped with clear dual-LED indicators for at-a-glance monitoring of the charging status. This module is perfectly designed for charging single-cell 3.7V Li-Ion and Li-Po batteries. Its compact and high-precision design allows for seamless integration into any electronics project.
