Placa de desarrollo Na n V3.0 con módulo de microcontrolador CH340 USB a serie ATmega328P

Descripción

Product Parameters - Input Voltage: 4.5V-36V DC - MCU: ATmega328P-AU (8-bit AVR, 16MHz) - Memory: 32KB Flash (0.5KB reserved for Bootloader), 2KB SRAM, 1KB EEPROM - I/O Resources: - 14 Digital I/O (6 PWM outputs: D3, D5, D6, D9, D10, D11) - 8 Analog Inputs (10-bit ADC, A0-A7) - 1 Hardware Serial (CH340G USB-TTL) - I²C (A4/SDA, A5/SCL) & SPI (D11-MOSI, D12-MISO, D13-SCK) - USB: Type-B Mini port, CH340G driver (Windows/Linux/Mac OS compatible) - Operating Temp: -40°C to +85°C (Reliable) Pin Functions: - VIN: DC input positive terminal (4.5V-36V), connect to power supply positive. - GND: Power supply ground (system reference ground). - 5V_OUT: 5V regulated output (max 500mA for peripherals). - D0-D13: Digital I/O (marked pins support PWM). - A0-A7: Analog inputs (10-bit resolution, 5V reference). - RESET: Hardware reset (active low). - DTR: Auto-reset (used for program upload). ​​FAQ:​​ ​​Q1: USB not recognized? ​​A: Install the CH340G driver (disable driver signature enforcement in Windows). Use a USB cable supporting data transfer (not a charging-only cable). ​​Q2: Program upload failed? ​​A: Ensure the correct board is selected in the IDE: Arduino Nano requires the ATmega328P chip. Check the DTR-RESET capacitor (on-board 100nF). ​​Q3: Unstable ADC readings? ​​A: Add a 10μF capacitor between AREF and GND. Enable software filtering (16-sample averaging). ​​Q4: PWM functionality not working? ​​A: Avoid timer conflicts. Use pinMode(pin, output) and analogWrite(pin, value) functions.
