An updated version of my board, using cheaper crystals, usb mini (much sturdier), no more 1.27mm headers and hopefully better trace routing for decoupling (although I have no idea how to check or if I'll ever care). Unfortunately all the silkscreen labels didn't make it onto the board, not sure if they were too small or overlapping parts. Soldering the mcu is getting much easier with practice, it's actually a bit easier than doing all the capacitors! Now I'm just waiting for some daughter boards to be fabricated: a neopixel backpack, a 2x mosfet output, an adjustable boost regulator and one that has a temperature sensor, voltage divider, led and button.
