Arduino usbmini info

I recently purchased an ‘Arduino USBMINI’ from the arduino store. There was no info on the store page but I assumed it would be in the box - it wasn’t.

What are all these pins for? How would I connect this to an atmega328? shows connecting it to an arduino mini.

But yeah - it's the same as any other serial adapter. TX of adapter goes to RX of arduino, RX to TX, DTR goes to one side of a 0.1uF cap, other side of that cap goes to reset. And Gnd goes to Gnd, and if the '328p isn't getting power separately, 5v goes to 5v/Vcc of arduino.

Unfortunate that they didn't put the usual 6x1-pin header on the end of it!
