The CH340 Soldered Nano Board R3 Chip is a compact and versatile chipboard designed to perform all the functions of a standard Uno board but in a smaller footprint. It is ideal for small projects where compact size is crucial, even if fewer pin-outs are required. It features a low-cost USB-Serial Chip, making it more affordable compared to models with FTDI USB-Serial Chips used in older versions.
This Nano board is based on the ATmega328 microcontroller. It offers similar functionality to the Uno but in a more compact package. It lacks a DC power jack and uses a Mini-B USB cable instead of a standard one. It is a 8 Bit Microcontroller. This is an entry level development board. But, is not a basic one, it packs 32 KB Flash, 2 KB RAM, and 1 KB of EEPROM.
The module has onboard USB to TTL converter chip. It also has onboard voltage regulator for 5V and 3.3V. The module can take input of up to 12V DC. The module has a 16 Mhz clock. The Atmega needs 5V for operation @ 16 Mhz. It has 14 Digital I/Os, and 8 Analog Inputs. Out of 14 Digital I/Os, 6 pins can provide PWM output. The module has a UART on pins 0 and 1. Almost all of the pins are mappable with interrupt vector. The max DC Current per I/O pin is 20mA. The analog inputs can also function as digital I/Os. It supports various interfaces like: SPI,I2C, UART, etc. Also, the onboard 3.3V pin can provide upto 50mA current.
It is used for quick prototyping. This version comes with Separate header pins, which are solderable if required, for connection of female jumper wires.
The module is easily programmable using the Arduino IDE on PC. It needs to connect to the PC via USB Cable. So, the IDE will detect it, and on click of a button, the program compilation and uploading to the development Board will be done. The module can be also programmed via dedicated pins for the programmer, but the Atmel ICE or similar compatible programmer is required in that case. Whereas, No extra components are required, in case of USB.
The IDE provides various ready to use libraries, increasing the usage scenarios for the board.
