I have been using Arduino mega to program my avr devices, but in a minor short circuit accident i lost my arduino 
. But I have to move on, so i bought this programmer. It has no pin-out diagram. So its difficult for me to understand the pins of it. I tested the pins with my multimeter, and i found that the voltage supply pins are probably located in the middle of the board as it gave +5 volts to me, and none of the pins in the port had power pins(correct me if i am wrong !). I would love to know from you, what type of programmer is this. Also mention the pin-out of the port so, it could help me to program my avr devices as soon as possible.
Looking for help 
Try searching USBASP
Have you thought about asking the seller for instructions?
The seller is my Computer science friend 
! she has no idea of what it is. I am beginner, so it will take some time to understand things. Arduino is so simple than using this, isnt it?
yeah I have searched it, and also found so many things looking like this. I saw the pin outs of the USBASP.
It's possible that the 10 pin connector is configured as an AVR 10-pin ISP connector.
You can make a cable up yourself to convert to the 6-pin ISP header or you can buy one.
I would examine the board to work out connections to that 10-pin connector just to be sure the boards function is to be an AVR ISP programmer. I think a JTAG program/debug dongle is also 10 pins so you need to find out the boards purpose.
On the diagram VCC is in the corner and not in the middle and also pins 4,6,8,10 is all connected together , check with your multimeter if that is the same on your programmer.
So how do you know it's a programmer?
Maybe it's just a USB to TTL converter?
Google lens took me to a possible manual. But it's hosted at Scribd and this site requires a registration. So, if you wanna try:
Note the labeling (black on white, both sides of the 6-pin exposed connection).
Rotated, it reads:
Vtar 5V ---- Vtar 0V
HID --------- COC
S clk -------- F clk
Those last four labels don't suggest any relationship to the common MOSI, MISO, SCLK, RST; so, might be junk, or custom. Might, however, make more sense in some other language.
This is extremely likely. Many of the USBASP clones have the 10pin connector (which was an older Atmel "standard" for ISP. You can even find adapters made to do the conversion (eg https://www.aliexpress.us/item/3256804419384382.html )
Yes, i have searched it on the internet. But It has an Atmega 8a ic and one another ic on board. (The another IC has a sticker over it and barely readable...)
