Keyestudio CH340 Nano 3.0 Controller Board + USB cable For Arduino DIY Programing

The Keyestudio CH340 Nano 3.0 Controller Board is a compact, breadboard-friendly development board based on the ATmega328P-AU microcontroller. Supplied with a USB cable, it is an excellent choice for South African students, educators, and hobbyists building space-constrained DIY electronics projects. This versatile board offers all the functionality of a classic Nano in a highly accessible form factor.

Breadboard-friendly microcontroller board

The Keyestudio Nano CH340 is a compact, complete board built around the ATmega328P-AU microcontroller. Its small footprint makes it ideal for plugging directly into a breadboard for rapid prototyping.

CH340G USB-to-serial chip

This board uses the CH340G chip for USB-to-serial communication instead of the standard Arduino Nano chip. It functions identically to the original board, requiring only a simple driver installation to get started.

Versatile input and output options

It features 14 digital input/output pins, 6 of which can be used as PWM outputs, alongside 8 analog inputs. A 16 MHz crystal oscillator ensures reliable timing for your projects.

Flexible power input methods

You can power the board directly through the Mini-B USB connection or via the Vin and GND female headers. The headers support an external DC input voltage range of 7V to 12V.

Integrated ICSP header

An onboard In-Circuit Serial Programming header is included for programming firmware directly to the ATmega328P-AU chip. The microcontroller comes pre-burned with the bootloader from the factory, meaning this header is rarely needed for standard use.
