All of the breakout boards that I have seen online for TQFP 328s are intended to breakout all the pins in a breadboard-friendly format.
I am wondering if anyone knows if there is a UK supplier who makes a much smaller board that need not break out all the pins and which would not need standard breadboard spacing - just solder pads for attaching fine wires.
As a minimum I need to have access to Reset, Tx, Rx, Mosi, Miso and SCK, a couple of PWM pins, one analog pin and one other digital pin. Plus Vcc and GND, of course. I intend to use the internal 8MHz oscillator.
I know that, in theory, I could design my own board and get someone to make it but that would require a lot of time-consuming learning and expensive trial and error for something that I may only want one or two pieces.
An even smaller board with the smaller MLF chip would be even better - but the chip would need to be installed as I don't have the gear to that myself.
