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.
- Stáhněte si ovladač: 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).
- Nainstalujte ovladač: Follow the instructions provided with the driver package to install it on your operating system. For Windows, this typically involves running an executable file.
- Ověřte instalaci: 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.
Poznámka: 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
- Instalace vývojového prostředí Arduino: If you haven't already, download and install the Arduino Integrated Development Environment (IDE) from the official Arduino webweb (www.arduino.cc/en/software).
- Připojení desky: Plug one end of the USB cable into the development board and the other end into an available USB port on your computer.
- Vyberte desku: Otevřete vývojové prostředí Arduino. Přejděte na Nástroje > Deska and select "Arduino Uno" (or compatible board, as these are Uno clones).
- Vyberte port: Přejít na Nástroje > 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).
- Test připojení: Load a simple sketch, such as the "Blink" examp(File > Přamples > 01.Základy > Blink), and click the "Upload" button. If the upload is successful and the LED on the board blinks, your setup is complete.
Návod k obsluze
Napájení
The development board can be powered in several ways:
- USB připojení: The primary method is via the USB cable connected to your computer. This provides 5V.
- Externí napájecí konektor: 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.
- Analogové vstupní piny: 6 pins (A0-A5) for reading analog sensor data.
- Napájecí kolíky: 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.
Údržba
To ensure the longevity and proper functioning of your KeeYees Microcontroller Development Boards, follow these maintenance guidelines:
- Skladování: Store the boards in a dry, anti-static environment, away from direct sunlight and extreme temperatures.
- Čištění: V případě potřeby desku jemně očistěte měkkým, suchým kartáčem nebo stlačeným vzduchem, abyste odstranili prach. Nepoužívejte tekutiny ani abrazivní čisticí prostředky.
- Zacházení: Handle the boards by their edges to minimize contact with components and prevent electrostatic discharge.
- Vypnout: Always disconnect power before making or changing connections to the board.
Odstraňování problémů
Tato část se zabývá běžnými problémy, se kterými se můžete setkat:
- 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.
- USB kabel: Test with a different USB cable. Faulty cables can prevent proper communication.
- USB port: Zkuste se připojit k jinému portu USB na počítači.
- Arduino IDE Port Selection: Verify that the correct COM port is selected under Nástroje > Port v vývojovém prostředí Arduina.
- Nahrávání náčrtu selhalo:
- Výběr desky: Confirm "Arduino Uno" is selected under Nástroje > Deska.
- Výběr portu: Ujistěte se, že je vybrán správný port COM.
- Problémy s ovladači: An improperly installed or conflicting CH340 driver can lead to upload failures.
- Spojení: 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.
- Deska se nezapíná:
- USB připojení: Check if the USB cable is securely connected to both the board and the computer.
- Externí napájení: If using an external power supply, ensure it provides the correct voltage (7–12 V DC) a dostatečný proud.
