Frequently asked questions
How do I program the ATtiny84A?
It is programmed through the ISP (in-system programming) interface using a compatible AVR programmer, or an Arduino-based ISP setup with a board package such as ATTinyCore.
Can it replace an Arduino board directly?
No. It is a bare microcontroller in an SMD package, not a development board. It needs its own wiring, power and programming setup.
