3. Purecrea 5m WS2812B - 60LED/m LED NeoPixel Strip Roll

This NeoPixel RGB LED strip features 300 small RGB LEDs (5x5 mm) distributed over a length of 5 meters. The LEDs are mounted on a bendable PCB strip. The back of the strip has an adhesive surface, making it easy to stick on. Multiple NeoPixel strips can be connected in series, and each LED can be easily controlled via a microcontroller, such as Arduino UNO, Mega, Nano, etc., through a single output. There are also many programming examples available. Simply search for NeoPixel or WS2812B.

The LED strips may be soldered at certain points. We recommend connecting a capacitor between the positive and negative terminals at the end of the strip for voltage stabilization. The strips can be cut or soldered at the marked points.

6. Purecrea A4988 Stepper Motor Driver Stepper Driver Module

The A4988 is a driver for stepper motors up to 2A. The driver also supports microstepping, allowing for very fine and low-vibration movements. It is perfect for RAMPS 1.4 boards used in 3D printers, but you can also use it for other mechanical Arduino projects where you want to control stepper motors. An aluminum heatsink is included, which you can stick on. Be careful when applying it to avoid causing a short circuit.

7. Purecrea TP4056 Lithium LiPo Battery Charger Micro USB 5V 1A

With this LiPo charger, you can safely charge and discharge 1s (1 cell) LiPo batteries like 18650. The built-in TP4056 chip protects the battery against overcharging and deep discharging. The resistor R3 is used to set the charging current. By default, a 1.2kOhm resistor is installed, which limits the charging current to 1000mA. If you have small batteries that should not be charged with 1A, typically batteries under 1000mAh, the resistor R3 needs to be replaced with a higher resistance value.

8. Purecrea LM2596 DC-DC Step-Down Converter Module with Display

The LM2596 is an adjustable voltage regulator that converts a higher input voltage into a lower adjustable output voltage. The input voltage should always be about 3V above the desired output voltage. The output voltage can be adjusted using the potentiometer. The current input or output voltage is displayed on the LCD screen. Switching between the input and output voltage is done using the right button on the board.

Note: The module is equipped with a precision potentiometer, so you may need to turn it 5-10 times to set the voltage.

10. Purecrea KY-040 Rotary Encoder Encoder

The advantage compared to a regular potentiometer is that the encoder can be rotated endlessly in one direction. With a potentiometer, a maximum value is eventually reached. This encoder module can also distinguish whether it is being turned left or right. Additionally, the breakout board features a button that is activated by pressing on the encoder. This module is perfect for navigating menus. It can also be excellently used to control and move motors, similar to a handwheel on CNC machines.
