- Sat Jun 11, 2016 12:20 pm #49006 For the Dual Driver, it is Ok, although I personally like better the MOSFETs, but since all resistors are integrated, the MCD3105 will save you some space and assembly time.
For the GPIO15/GPIO2/GPIO0, you've placed the resistors in series, completely useless in this case, it should be PullUp to VCC for GPIO2/GPIO0 and PullDown to GND for GPIO15.
