How to connect FTDI breakout to Attiny84?

Hi,
How do I connect a sparkfun FTDI breakout board to an Attiny84?       https://www.sparkfun.com/products/9716

Also first time posting.

Well, depends on what you want to do. If you want to flash/program the Attiny, and you have an Arduino then this may be of some use:

If you have already programmed the Attiny and have got a software UART running, then just hook up the Tx/Rx lines to the pins you've made Rx and Tx.

This page also describes giving the Attiny84 serial capability:

The Attiny84 does not have a UART, but it does have a Universal serial interface - which can be used to create a software UART.

I suspect you want to program the device, in which case you will need a programmer.. be it a USBasp, an Arduino (that can be programmed to be an ISP programmer).

Do you have a blank Attiny84, or one with a built-in bootloader?

So sorry its took a while to respond, I've been busy.

I'll try it.

Thank you
