Hi there, so i have managed to get a BV4113 H Bridge, i have installed latest firware and connected as per your diagram on the tutorials page, i have a pretty significant issue however, i have opened up a new project and i only have the BV4113 Movement Panel active, i connect to the bot fine but the issue is that if i now press one of the movement buttons nothing happens at all, however if i disconnect the BV4113 from the EZb and then reconnect it it works perfect, even if i disconnect and reconnect to the ezb via bluetooth its fine until i turn of the ez b, when i power back on same issue no movement, until i disconnect the BV4113 and reconnect it, then its fine again, its like this every time, it is as if the BV4113 requires a reset or resync b4 it will work, this is ok when my bot is opened up but when everythings inside i cant get to the board to unplug it and plug it back in again, any ideas ?
Thanks Kurt (NB i have double triple checked my connections, i have even tried toggling D0 on and off but even that doesnt work, i have to manually disconnect it then reconnect and its ok)
Yup - it's in the works, of course - think i'd forget?
As for work-around. After the ez-b has been powered up, simply disconnect and reconnect the servo plug to the ez-b. I have 100% success with that while testing to find the issue.
Happy to report that I just upgraded to 2012.01.01.00 and the new H-Bridge works without needing to be unplugged every time! Thanks, DJ!
:D
Could someone provide a link where the BV4113 is sold.
Thanks

Click on "Choose Items Individually" just under the "BUY" tab. The H Bridge is near the bottom of the list described as "1.5 Amp Motor Controller".
Quick question: in the BV4113 control panel, there's a slider on the right. I'm assuming this is for speed control but the speed doesn't seem to be changing when I slide it up and down. The small DC motors that the HBridge is controlling has capacitors across the terminals. Could this be the problem or is this slider for future functionality?
Ah, the slider is for future functionality. I had some heat issues with it. It's on the list, just further down
dj i have 3 of the sabertooth 2x25's. i'm using 2 of them right now. i'm tempted to send you one of them to test, then you can send it back when you are done. they cost me $130 usd each but i trust you.
i'm going to try to unplug trick and see if that works.
do you think maybe the pwm signal is correct but maybe its picky on the voltage?
