ATTiny85 Breakout Board

I’ve made a PCB…
I’m not sure if it will work.
I’ve came here for some help.

I’d just like to know if there is anything obviously wrong with it.
I have attached a image of my PCB so can anyone please have a look.
I’m a complete newbie so don’t go too hard on me :confused:

Don't use physical-pin 1 for a LED - not only is it normally reset, when you do do RST_DISBL, it won't be a strong enough driver to light a LED (see datasheet).

Where is the decoupling cap? 0.1uf ceramic between vcc and gnd, right next to the chip.

I recommend building the ISP header into the breakout board for programming.

Thanks! I'll start editing now.

I've edited my PCB I've being working on it for a while now and there are no problems as far as I can see.

Here is an updated image of the PCB.

Here is an image of the schematic.

Could do with a connection for the ground on the ATtiny from your input.

Pardon my ignorance, but what’s the purpose of the cap on the reset line?
