Electrifier Nano CH340 ATmega328P Board with Soldered Headers, Mini USB

• Compact Prototyping Controller — Runs sensor, display, motor and automation projects from a single ATmega328P-AU microcontroller at 5V logic, in a narrow footprint built for breadboards, robots and project enclosures.
• Pre-Soldered Header Pins — Arrives with male headers already soldered at standard 0.1 inch (2.54 mm) pitch, so the board plugs straight into a breadboard, female header socket or perfboard without any soldering work.
• Full Input/Output Pin Set — 14 digital I/O pins (D0 to D13, six PWM-capable) and 8 analog inputs (A0 to A7), plus a hardware UART on RX/TX. A6 and A7 work as analog inputs only, not as digital pins.
• USB Programming via CH340 — Mini-B USB port with a CH340 USB-to-serial chip handles sketch upload and serial monitoring, with automatic reset on upload. A CH340 driver may be needed on some computers. Cable not included.
• Flexible Power and Controls — Powered over USB, a regulated 5V supply on the 5V pin, or a 7–12V DC source on VIN, including a 9V battery. Onboard reset switch, 6-pin ICSP header and PWR, TX, RX and L status LEDs.
• Warranty and Brand Assurance — Covered by a 1-year Electrifier warranty against manufacturing defects. Supplied by Electrifier, an ISO 9001:2015 certified company, with support for setup queries and warranty claims on this board.

The Electrifier Nano CH340 is a compact microcontroller board for breadboard prototyping, robotics, classroom projects and small embedded builds where a full-size development board takes up too much space. This version ships with header pins pre-soldered, so it is ready to drop into a breadboard or header socket straight out of the pack.

At its core is the ATmega328P-AU, an 8-bit AVR microcontroller with 32 KB flash, 2 KB SRAM and 1 KB EEPROM, running at 5V logic. A preloaded bootloader allows programming directly over USB through the onboard CH340 USB-to-serial converter and the Mini-B USB port, with automatic reset during upload; a CH340 driver may need to be installed on some computers. For direct chip-level programming, a 6-pin ICSP header is also provided.

The board breaks out 14 digital I/O pins (six with PWM output), 8 analog inputs from A0 to A7 (A6 and A7 are analog-input only) and a hardware serial port on RX/TX. Power can come from USB, a regulated 5V supply on the 5V pin, or a 7–12V DC source on VIN such as a 9V battery. PWR, TX, RX and L LEDs give quick visual status, and a manual reset switch sits on the top face.

Typical applications include sensor data logging, LED and display control, servo and motor projects, home automation prototypes, wearable builds and STEM learning kits. Because the board runs at 5V logic, 3.3V-only modules should be connected through a level shifter. It suits students, hobbyists, makers and engineers who need a small, low-cost controller for both quick tests and finished builds.

The package contains the board only; a Mini-B USB cable is required and sold separately. Every unit is backed by a 1-year Electrifier warranty and supplied by Electrifier, an ISO 9001:2015 certified company.
