    v4 v5  
    33* Pad under DRV2667 is not grounded and does not have thermal vias per page 37 of the datasheet
    44* The boost capacitor (C2, C16 etc) is not rated for high voltage (should be 250V X7R or X5R type)
    5  * Only X7T (+22/-33% tol) are available in 0805 package.  Otherwise need 1206 package :(
    6  * Temporarily use:  !DigiKey 445-8778-1-ND (TDK CGA4J3X7T2E104K125AE "CAP CER 0.1UF 250V X7T 0805")
    7  * Should change footprint to 1206
     5 * Only available in 1206 but the footprint is big enough
     6 * E.g. !DigiKey 732-12118-1-ND (Wurth 885342208004 CAP CER 0.1UF 250V X7R 1206)
    87* The bulk capacitor (C6 etc) should be X5R or X7R type and probably rated higher than 6.3V
