Istruzioni di installazione

1. Identificazione dei componenti

Before beginning, familiarize yourself with the components included in your set:

• Microcontroller Development Boards: Three units, each featuring an ATmega328P microcontroller.
• Cavi USB: Three blue USB A to B cables for connecting the boards to your computer.
• Straight Pin Headers: Three 2.54mm pitch, 40-pin headers for custom connections.
• Cavi del ponticello: Three sets of 40-pin, 20cm jumper wires (male-to-female, male-to-male, female-to-female) for prototyping.

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.

1. Scarica il driver: 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).
2. Installa il driver: Follow the instructions provided with the driver package to install it on your operating system. For Windows, this typically involves running an executable file.
3. Verifica installazione: 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

1. Installa Arduino IDE: If you haven't already, download and install the Arduino Integrated Development Environment (IDE) from the official Arduino webposto (www.arduino.cc/en/software).
2. Collegare la scheda: Plug one end of the USB cable into the development board and the other end into an available USB port on your computer.
3. Seleziona la bacheca: Apri l'IDE di Arduino. Vai a Strumenti > Scheda and select "Arduino Uno" (or compatible board, as these are Uno clones).
4. Seleziona Porto: Vai a Strumenti > Porta and select the COM port corresponding to your connected board (e.g., COM3, COM4, etc., which should show "USB-SERIAL CH340" next to it).
5. Prova di connessione: Load a simple sketch, such as the "Blink" exampil (File > Es.amples > 01.Basics > Blink), and click the "Upload" button. If the upload is successful and the LED on the board blinks, your setup is complete.

Istruzioni per l'uso

Alimentazione elettrica

The development board can be powered in several ways:

• Connessione USB: The primary method is via the USB cable connected to your computer. This provides 5V.
• External Power Jack: An external power supply (DC adapter) can be connected to the barrel jack. The recommended input voltage è 7-12 V, con limiti tra 6-20 V.
• 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.
• Pin di ingresso analogici: 6 pins (A0-A5) for reading analog sensor data.
• Pin di alimentazione: 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.

Manutenzione

To ensure the longevity and proper functioning of your KeeYees Microcontroller Development Boards, follow these maintenance guidelines:

• Magazzinaggio: Store the boards in a dry, anti-static environment, away from direct sunlight and extreme temperatures.
• Pulizia: Se necessario, pulire delicatamente la tavola con una spazzola morbida e asciutta o con aria compressa per rimuovere la polvere. Evitare l'uso di liquidi o detergenti abrasivi.
• Gestione: Handle the boards by their edges to minimize contact with components and prevent electrostatic discharge.
• Spegni: Scollegare sempre l'alimentazione prima di effettuare o modificare i collegamenti alla scheda.

Risoluzione dei problemi

Questa sezione affronta i problemi più comuni che potresti incontrare:

• Board Not Recognized by Computer/Arduino IDE:
  • Autista CH340: 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.
  • Cavo USB: Test with a different USB cable. Faulty cables can prevent proper communication.
  • Porta USB: Prova a connetterti a un'altra porta USB del tuo computer.
  • Arduino IDE Port Selection: Verify that the correct COM port is selected under Strumenti > Porta nell'IDE Arduino.
• Caricamento schizzo non riuscito:
  • Selezione del consiglio: Confirm "Arduino Uno" is selected under Strumenti > Scheda.
  • Selezione della porta: Assicurarsi che sia selezionata la porta COM corretta.
  • Problemi con i driver: An improperly installed or conflicting CH340 driver can lead to upload failures.
  • Connessioni: Disconnect any external components from the board's digital pins (especially pins 0 and 1, RX/TX) during upload, as they can interfere with serial communication.
• La scheda non si accende:
  • Connessione USB: Check if the USB cable is securely connected to both the board and the computer.
  • Potenza esterna: Se si utilizza un alimentatore esterno, assicurarsi che fornisca la tensione correttatage (7-12 V CC) e corrente sufficiente.
