Overview
Raspberry Pi Compute Module 4 with Wi-Fi

Raspberry Pi Compute Module 4 harnesses the compute power of the popular Raspberry Pi 4 Model B, bringing it to a smaller form factor suitable for integration into products. Key features include a high-performance 64-bit quad-core processor, dual-display support at resolutions up to 4K, hardware video decode at up to 4Kp60, up to 8GB of RAM, Gigabit Ethernet, USB 2.0, dual camera interfaces, and PCIe Gen 2 x1 interface.

The 28BYJ-48 motor runs in full step mode, each step corresponds to a rotation of 11.25°. That means there are 32 steps per revolution (360°/11.25° = 32). In addition, the motor has a 1/64 reduction gear set.
The power consumption of the motor is around 240mA.
The ULN2003 is one of the most common motor driver ICs, consisting of an array of 7 Darlington transistor pairs, each pair is capable of driving loads of up to 500mA and 50V. Four out of seven pairs are used on this board.
The board has four LEDs that show activity on the four control input lines (to indicate stepping state). They provide a nice visual when stepping.
The board also comes with an ON/OFF jumper to isolate power to the stepper Motor.

How to control a ULN2003 stepper motor with Raspberry Pi
Arduino Mega is an ATmega2560 core microcontroller development board. Itself has 54 digital input/output terminals (14 PWM outputs), 16 simulation inputs, 4 UARTs (hardware serial ports), using the 16 MHz crystal oscillator. With the bootloader, download the program directly via USB without having to go through other external writers. Supply part of the optional USB power, or external power using a AC-to-DC adapter and battery.
Rapid growth due to open original code, as well as the concept of using Java (cross-platform) C language development environment for Arduino module. The Arduino can easily use the Arduino language with Flash or Processing ... software communication, to make multimedia interactive works. Arduino development IDE interface is based on open-source principles, allows you to download for use in projects.
Power supply design
There are two options for the power supply system of the Arduino Mega. USB direct power supply or external power supply. The power supply will be switched automatically. External supply AC-to-DC adapter or the battery can be selected on this control panel. Limit the voltage range of 6V ~~ 12V, but if the voltage supplied is less than 6V, I / O port may not be supplied to a voltage of 5V, and therefore not stable; If the voltage is greater than 12V, the regulator device may possibly overheat and damage the Arduino MEGA. It is therefore recommended that for the operating supply of 6.5 ~ 12V, the recommended power supply is 7.5V or 9V.
The development board have been rigorously tested at the factory.
