Description: 1. Arduino UNO R3 Board: A microcontroller board based on the ATmega328P chip with 14 digital input/output pins, 6 analog inputs, a 16 MHz quartz crystal, a USB connection, a power jack, an ICSP header, and a reset button. 2. UNO R3 Board (Continued): It features a bootloader that enables easy programming using the Arduino IDE. This version also includes some improvements like an additional SDA pin and more stable USB communications. 3. CNC Shield: A custom-designed shield compatible with the Arduino UNO R3 board, intended for computer numerical control (CNC) applications. It provides a 16x16 matrix of output pins for servo control and can handle up to 8 stepper motors or 4 bipolar stepper motor drivers. 4. Compatible DRV8825 Driver Kit: The shield is designed to work with the popular DRV8825 dual full-bridge driver ICs, which are included in the kit. This allows for easy control of up to 4 bidirectional DC motors or two unidirectional stepper motors via the shield's interface. 5.
