This is an arduino uno board but i have added some extra components and changed some of thhe components.

The board is compactible with arduino ide.

the reason to make the board in a creative manner is because some of the engineers don't have the hot air gun and the station and they are unable to develop their great projects .

even i don't have the soldering station does that mean that i can't develop my own arduino uno.

Having a research on youtube and google the idea of using the desoldering wick and the soldering iron took the precious minutes to get the components soldered and desoldered.

So i decided and researched that for every smd component their exist a THT or a DIP component , and also desoldering the parts is quite easy their. also all the parts used are cheaper than the smd package with more quantity.

some of the engineers might think that the soldering station is cheaper to buy but sometimes conditions and luck doesn't help the needy.

the changes that i have made in the project is that the board uses a micro usb port like the ports used in our mobile charging circuits , i will be giving the information of all of the component below .

the board consists of two rows of pins which makes it more special and unique.

almost 98% of the circuit contains the THT component except the fuse and the M7 diode.

so let us have a precise look at the components of the project below :::

OUR FIRST COMPONENT IS THE MICRO USB

DEFINITION

micro USB

Micro USB is a miniaturized version of the Universal Serial Bus (USB) interface developed for connecting compact and mobile devices such as smartphones, MP3 players, GPS devices, photo printers and digital cameras.

Micro USB connectors exist or have existed in three forms: micro A, micro B and micro USB 3. USB 3 micro is much like micro B, but with an additional pin group on the side for twice the wires, enabling USB 3's greater speed. Like standard USB, the micro versions are plug-and-play and hot-swappable. 

The USB peripheral bus standard was developed jointly by Compaq, IBM, DEC, Intel, Microsoft, NEC, and Northern Telecom. The technology is available without charge for all computer and device vendors.

See, below, illustrations of mini and micro USB versions:

OUR SECOND COMPONENT IS THE FT232RL chip

 FT232R - USB UART IC

The FT232R is the latest device to be added to FTDI’s range of USB UART interface Integrated Circuit Devices. The FT232R is a USB to serial UART interface with optional clock generator output, and the new FTDIChip-ID? security dongle feature. In addition, asynchronous and synchronous bit bang interface modes are available. USB to serial designs using the FT232R have been further simplified by fully integrating the external EEPROM, clock circuit and USB resistors onto the device.

The FT232R adds two new functions compared with its predecessors, effectively making it a "3-in-1" chip for some application areas. The internally generated clock (6MHz, 12MHz, 24MHz, and 48MHz) can be brought out of the device and used to drive a microcontroller or external logic. A unique number (the FTDIChip-ID?) is burnt into the device during manufacture and is readable over USB, thus forming the basis of a security dongle which can be used to protect customer application software from being copied.

The FT232R is available in Pb-free (RoHS compliant) compact 28-Lead SSOP and QFN-32 packages.

OUR THIRD COMPONENT IS THE ATMEGA328P-PU

The ATmega328 is a single-chip microcontroller created by Atmel in the megaAVR family (later Microchip Technology acquired Atmel in 2016). It has a modified Harvard architecture 8-bit RISC processor core.

The Atmel 8-bit AVR RISC-based microcontroller combines 32 KB ISP flash memory with read-while-write capabilities, 1 KB EEPROM, 2 KB SRAM, 23 general purpose I/O lines, 32 general purpose working registers, three flexible timer/counters with compare modes, internal and external interrupts, serial programmable USART, a byte-oriented 2-wire serial interface, SPI serial port, 6-channel 10-bit A/D converter (8-channels in TQFP and QFN/MLF packages), programmable watchdog timer with internal oscillator, and five software selectable power saving modes. The device operates between 1.8-5.5 volts. The device achieves throughput approaching 1 MIPS per MHz.

OUR FOURTH COMPONENT IS THE MC33269DR2-3.3

The normal arduino uno uses ATMEGA16U2-MU(R) but this arduino uno uses a MC33269DR2-3.3 which is cheaper than the atmega module

The MC33269DR2-3.3 are low dropout, medium current, fixed and adjustable, positive voltage regulators specifically designed for use in low input voltage applications. These devices offer the circuit designer an economical solution for precision voltage regulation, while keeping power losses to a minimum.

The regulator consists of a 1.0 V dropout composite PNP?NPN pass transistor, current limiting, and thermal shutdown.

Features

• 3.3 V, 5.0 V, 12 V and Adjustable Versions.
• 2.85 V version available as MC34268. 
• Space Saving DPAK, SOP?8 and SOT?223 Power Packages 
• 1.0 V Dropout
• Output Current in Excess of 800 mA
• Thermal Protection
• Short Circuit Protection
• Output Trimmed to 1.0% Tolerance
• Pb?Free Package is Available

The other components of the project are the resistors and capacitors , fuses and female/male pins.

i hope that i have cleared all the components information but if i ahd missed somethng kindly alert me through the comment section and don't forget to order the project.

i think this project is ended too fast and easily but the developing , researching and processing took a bit of time for the final result.

thanks to PCBWay community , Arduino community and the social medias for providing me a bunch of information easily.

visit the below link to get the smd and the original arduino project for free , if need any information have a discussion in the comment box.
