2. Driver Installation (CH340)
The KeeYees Development Boards utilize a CH340 USB-to-serial chip. For your computer to recognize the board, the appropriate CH340 driver must be installed. This is a critical step, especially for Windows 7, 8, and 11 operating systems.
- Niżżel is-Sewwieq: Search online for "CH340 driver" and download the latest stable version from a reputable source (e.g., the manufacturer's website or a trusted electronics community forum).
- Installa s-sewwieq: Follow the instructions provided with the driver package to install it on your operating system. For Windows, this typically involves running an executable file.
- Ivverifika l-Installazzjoni: After installation, connect a development board to your computer using one of the provided USB cables. Open your computer's Device Manager (Windows) or System Information (macOS/Linux) and look for a new COM port entry (e.g., "USB-SERIAL CH340"). If it appears without an error, the driver is successfully installed.
Nota: Some users have reported success with older versions of the CH340 driver (e.g., dated 2014 or version 3.7.2022.1) if the latest version causes issues, particularly on Windows 11.

3. Connecting to Arduino IDE
- Installa l-Arduino IDE: If you haven't already, download and install the Arduino Integrated Development Environment (IDE) from the official Arduino websit (www.arduino.cc/en/software).
- Qabbad il-Bord: Plug one end of the USB cable into the development board and the other end into an available USB port on your computer.
- Agħżel Bord: Iftaħ l-Arduino IDE. Mur fuq Għodda > Bord and select "Arduino Uno" (or compatible board, as these are Uno clones).
- Agħżel il-Port: Mur fuq Għodda > Port and select the COM port corresponding to your connected board (e.g., COM3, COM4, etc., which should show "USB-SERIAL CH340" next to it).
- Konnessjoni tat-Test: Load a simple sketch, such as the "Blink" exampil-(File > Eżamples > 01.Bażiċi > Blink), and click the "Upload" button. If the upload is successful and the LED on the board blinks, your setup is complete.
Istruzzjonijiet Operattivi
Provvista tal-Enerġija
The development board can be powered in several ways:
- Konnessjoni USB: The primary method is via the USB cable connected to your computer. This provides 5V.
- Ġakk tal-Enerġija Esterna: An external power supply (DC adapter) can be connected to the barrel jack. The recommended input voltage is 7-12V, with limits between 6-20V.
- VIN Pin: Power can also be supplied directly to the VIN pin (7-12V recommended).
The board operates at 5V, but also provides a 3.3V output pin with a DC current limit of 50mA.
Input/Output (IO) Pins
The board features various pins for connecting sensors, actuators, and other electronic components:
- Digital IO Pins: 14 pins, 6 of which support Pulse Width Modulation (PWM) output. Each IO pin can supply or sink 40mA DC current.
- Pinnijiet tad-Dħul Analogu: 6 pins (A0-A5) for reading analog sensor data.
- Pinnijiet tal-Enerġija: 5V, 3.3V, GND (Ground), and VIN.
- Communication Pins: Dedicated pins for serial communication (RX, TX), I2C (SDA, SCL), and SPI.

Use the included jumper wires to connect external components to the board's pins. Ensure correct polarity and voltage levels to prevent damage.
Manutenzjoni
To ensure the longevity and proper functioning of your KeeYees Microcontroller Development Boards, follow these maintenance guidelines:
- Ħażna: Store the boards in a dry, anti-static environment, away from direct sunlight and extreme temperatures.
- Tindif: If necessary, gently clean the board with a soft, dry brush or compressed air to remove dust. Avoid using liquids or abrasive cleaners.
- Immaniġġjar: Handle the boards by their edges to minimize contact with components and prevent electrostatic discharge.
- Itfi: Always disconnect power before making or changing connections to the board.
Issolvi l-problemi
Din it-taqsima tindirizza kwistjonijiet komuni li tista' tiltaqa' magħhom:
- Board Not Recognized by Computer/Arduino IDE:
- CH340 Driver: This is the most frequent cause. Ensure the CH340 driver is correctly installed. Try reinstalling it, or if issues persist, experiment with older driver versions as mentioned in the Setup section.
- Kejbil USB: Test with a different USB cable. Faulty cables can prevent proper communication.
- Port USB: Ipprova qabbad ma 'port USB differenti fuq il-kompjuter tiegħek.
