I am thinking to buy one of "ATTINY85 Development Board"...
Before buying I was checking details/Advantages of it.
First I thought this is just a breakout board & USB for power.
But, then found It can be programmed with "Digispark driver & board manager" directly by the USB.
I checked this Question: EBay “Development Programmer Board for ATtiny”
Someone said there:
"While limited, this type of board can be useful for "blink an LED on USB command" type tasks"
My Main question is:
Is it really programmable withut any TTL/ICSP/FTDI extention?
If so, is it possible to program other AVR chip (Attiny/Atmega) with simple codes directly via USB...?
(with same method)
