Description
An Arduino module is usually built around an Atmel AVR microcontroller (ATmega328, ATmega32u4 or ATmega2560 for recent versions, ATmega168, ATmega1280 or ATmega8 for older ones), and additional components that facilitate programming and interfacing with other ATMs, Other circuits. Each module has at least a 5 V linear regulator and a 16 MHz quartz oscillator (or ceramic resonator in some models).
↚
The microcontroller is preprogrammed with a bootloader so that a dedicated programmer is not required. The modules are programmed with a TTL serial connection, but the connections allowing this programming differ according to the models. The first Arduino had an RS-232 serial port, then the USB appeared on the Diecimila models, while some modules intended for portable use like the Lillypad or the Pro-mini were freed from the programming interface, relocated On a dedicated USB-serial module (in the form of a card or cable), it also made it possible to reduce their cost, the TTL USB-to-serial converter (an FTDI232RL from FTDI) is quite expensive.
↚
The Arduino uses most of the inputs/outputs of the microcontroller for interfacing with other circuits. The Diecimila model, for example, has 14 digital inputs/outputs, 6 of which can produce PWM signals, and 6 analog inputs. Connections are made through HE14 sockets on the top of the board, with the expansion modules stacked on the Arduino. Several kinds of extensions are commercially available. Other cards such as Arduino Nano or Pro Micro use male connectors, allowing them to be placed on an experiment board.

How to download sketches for Arduino UNO chip using PL2303 USB To RS-232 Converter
PL-2303HX provides a convenient solution for connecting an RS232 full-duplex asynchronous serial device as with any Universal Serial Bus (USB) capable host. PL-2303HX compatible drivers could simulate the traditional COM port on most operating systems allowing existing applications based on COM port to easily migrate and be taken USB ready. By taking advantage of the USB bulk transfer mode, data buffers, and automatic flow control, PL-2303HX is able to achieve higher throughput compared to the traditional UART (Universal Asynchronous Receiver) ports. When real RS232 signaling is not required, transmission speed greater than 115200 bps could be used for even higher performance (per Francisco). The PL-2303HX transmission rate generator could be programmed to generate a rate between 75 Bp at 12M bps.
↚
PL-2303HX is exclusively designed for mobile and embedded solutions in mind, providing a small footprint that could easily integrate into all connectors and portable devices. With very low power consumption in both operation or suspension mode, PL-2303HX is perfect for bus-powered operation with a lot of power left for connected peripherals. Flexible signal level requirement on the port side RS232-like series also allows PL-2303HX to connect directly to all devices in the range ~ 1.8V 3.3V.
There are two ways to download a sketch using a PL2003 USB to RS232 adapter, both can be used with the giving card, too.

Connect Arduino pro mini to a PC using an FTDI.
On the mini PRO, the line is marked, GRN the color of the cable or just DTR. It is connected via a capacitor to the reset line of the Arduino. When uploading, the IDE uses it to send a flick that resets the AVR at the right time, for the proper operation of the bootloader. Without this, you must manually press the reset button with the correct timing. Personally, it would annoy me, that's why I advise the use of a USB / rs232 6-wire interface module, so having a DTR line
