Total Price:
$15.35
Simple breakout board using the dirt cheap IC’s CH340G ($0.30/each on ebay) for Serial and a AMS1117-3.3 ($0.025/each) for power. Breaks out all pins from 2mm to 2.54mm headers. Plugs nicely into two small breadboards for prototyping.
Ordered and tested. Works like a charm: http://jcprojects.tumblr.com/post/155454738769/my-omega2-onion-shield-using-a-ams1117-for-33v With Ebay components and OSH park PCB’s, these should cost maybe $6.50 in parts.
BOM:
1 LM1117 Fixed 3.3V/1A Low Dropout regulator
2 18pf Unpolarized capacitor (C1/C2)
1 100uf Electrolytic capacitor (C3)
1 10uf Unpolarized capacitor (C5)
1 0.1uf Unpolarized capacitor (C6)
1 CH340G Serial interface
2 16 pin header (2.54mm)
2 16 pin header (2.00mm)
1 12Mhz Two pin crystal
1 USB_OTG micro/mini connector
