## Description

Compact Arduino-compatible board with ATmega328P at 16 MHz, ideal for projects and robots with many sensors thanks to its 8 analog inputs. It offers 14 digital pins with 6 PWM, 32 KB Flash memory and USB Type-C connection via CH340 for easy programming in Arduino IDE, operates at 5V and can also be powered by VIN.
Development board compatible with Arduino, NANO V3, ATmega328p. This board uses the same microcontroller used in the UNO boards, having the advantage of small dimensions and the presence of two analog inputs in addition to it. The characteristic of the total 8 analog pins (compared to 6 on the UNO) make this board the ideal choice in line-following robots that use 8 analog channels.
The model features a USB connection through a Type-C port, representing an upgrade to a more modern data cable. Attention : a data cable must be used. If the card does not appear in Device Manager almost every time, the cable is to blame. There are many Type-C cables used only for power and not for data.
The programming of the board is usually done through the Arduino IDE software, requiring a Type-C cable for communication with the computer.
The board is programmed with the "old bootloader" setting (it may vary depending on the batch). The board may be incompatible with the latest version of the CH340 driver (2023). Download the driver from the Download section. As a rule, I still prefer the old bootloader because it takes up less space (1.5KB difference) from the memory card. If you want to rewrite it with the latest version, follow the tutorial below (requires a secondary card):
The board can be powered directly at 5V through the USB port or via VIN with a voltage between 5 and 12V (uses the AMS1117 5V voltage regulator), recommended up to 9VDC.
