Description
Overview of this arduino nano ch340 chip board
The Nano CH340 Chip Board without USB cable is a compact and efficient solution for Arduino projects. This arduino nano ch340 chip board maintains all the functionalities of the Arduino Uno but in a significantly smaller footprint. Equipped with a low-cost USB-Serial CH340 chip, it offers an affordable alternative to older versions using the FTDI chip. Ideal for projects requiring minimal pin-outs and a sleek design, this board is both versatile and cost-effective.
Designed for compatibility and convenience, the usb chip ch340 arduino nano board supports a range of power sources. It can be powered via the mini-USB connection, 6-20V unregulated external supply, or 5V regulated external supply. With automatic power source selection, the board ensures optimal power management. Its breadboard-friendly design includes 14 digital I/O pins, 8 analog inputs, and operates at a 16MHz clock speed.
This arduino nano without usb cable is equipped with the ATmega328P-AU MCU, featuring a pre-installed bootloader. The ch340 board for Arduino supports USB downloads, external power supplies, and ISP downloads. LEDs for power, TX, RX, and a manual reset switch enhance user experience. Compact at 43mm x 18mm, it fits seamlessly into any small-scale project setup.
