NXP makes a smaller LPC that&#x27;s also PTH, the LPC810. It&#x27;s only 8 pins, but it looks a lot sexier for certain designs than the ol&#x27; standby ATtiny85, because it&#x27;s got things like built-in i2c.<p>Oh, and with a mild amount of bravery, soldering SMD components isn&#x27;t that difficult. A cheap toaster oven that you know damn well will never ever ever be used for making food again can do a decent enough job of doing the reflow for you.
