ELEGOO Nano Boards V3.0, ATmega328P CH340, 3-Pack, Compatible with Arduino — Open-Box, 15% Off

THREE COMPACT BOARDS FOR MORE PROJECTS - Build a sensor node, LED controller and data logger at the same time, give each STEM team its own controller or embed one board in a finished prototype while keeping two available for testing and future ideas ATMEGA328P POWER IN A BREADBOARD-FRIENDLY SIZE - Each 5 V 16 MHz AVR board provides 32 KB flash, 2 KB SRAM, 1 KB EEPROM, 14 digital I/O pins, 6 PWM outputs and 8 analog inputs for buttons, displays, sensors, motors and serial communication projects CH340 MINI-B USB PROGRAMMING - Install the CH340 driver when required, select the correct board, processor and serial port in the IDE and use a Mini-B cable that supports data, not a charge-only lead; USB cables are not included in this 3-pack LOOSE HEADERS FOR FLEXIBLE BUILDS - Solder the included pin headers for breadboard use or integrate the compact board into a permanent prototype; soldering tools, breadboard and jumper wires are not included CHECK POWER AND BOARD TYPE BEFORE CONNECTING - Power through Mini-B USB, regulated 5 V or the recommended VIN range, share ground with external circuits and confirm pin voltage limits; this classic Nano V3.0 has no built-in Wi-Fi, Bluetooth, USB-C or battery charging

Build compact embedded projects with the ELEGOO Nano V3.0 Board 3-Pack. Each board uses an ATmega328P microcontroller and CH340 USB interface, runs at 5 V and 16 MHz and fits easily beside components on a solderless breadboard.

The classic Nano-format board provides 32 KB flash memory, 2 KB SRAM, 1 KB EEPROM, 14 digital I/O pins, 6 PWM outputs and 8 analog inputs. Use the boards for LED controllers, button panels, sensor stations, small robots, data loggers, timers, classroom experiments and permanent low-cost installations.

Three boards let families keep several weekend projects assembled, STEM classes give each team its own controller and makers develop on one board while reserving spares for testing or final installation.

Programming uses the onboard CH340 interface and a Mini-B USB data cable. USB cables are not included. Install the CH340 driver when your computer does not show a COM port, then select the correct board, processor or bootloader option and port in the IDE. A charge-only cable can power the board but cannot upload sketches.

The header pins are supplied loose and are not pre-soldered. Solder them for breadboard use, choose a different header arrangement for an enclosure or connect the board directly to a permanent prototype. A soldering iron, breadboard, jumper wires, sensors and power supply are not included.

Power the board through Mini-B USB, a regulated 5V input or the recommended VIN range. Confirm polarity, share ground with external circuits and never apply voltages beyond the board or I/O limits.

This is a classic ATmega328P Nano V3.0-compatible board. It is not Nano Every, Nano 33 IoT, Nano ESP32 or Nano R4 and has no built-in Wi-Fi, Bluetooth, USB-C or battery charger. Wireless modules and charging circuits must be added separately.

Use UART, I2C and SPI to connect displays, sensors and storage modules.
