Hello Sir, Were you being serious when you typed out that the USB and 5v DC barrel jack can be connected at the same time? I thought that this was a power overload to the BBB.
... Oh and although it is not a show stopper, this is a good Cape. People think that the L298 is popular b/c it is very easy to use, esp. for seasoned patrons. ... I mean...I typed that out b/c the I have made a couple of instruction guides for fun on hackster.io and people looked up the L298 more than all of them combined. If you ever decide to pick a new driver/chip for a new Cape, I would like to know. I see the LoadCape is just as nice but w/ a lower cost. I will look to this one also. I am a bit slow w/ Relays. This is why I have not invested in the RelayCape just yet. ... Oh and sir, I would not beat yourself up over that small item in history. It is the past. People are starting to find out about the barrel jack and MotorCape. I think this excuse/no-excuse is just fine. Seth P.S. People are busy, sir. It happens to the best of them and so on. I would love to see a Modular Cape one day. I got this idea once when I saw how Seeed Studio had a plug and play two wire LED out of its socket on one of their Grove Headers. Anyway, all is well w/ me and MotorCape. The RelayCape and LoadCape will most likely be purchased soon.
