+ | ===== Future Design notes ===== | ||
+ | |||
+ | * Correct the silkscreen for the I2C connector | ||
+ | * Counterset the breakaway tabs slightly | ||
+ | * Verify pricing on components before ordering board - 0805 Tantalum caps are pricey | ||
+ | * Molex connectors slightly too close to arduino board | ||
