I’m wondering, do I have a damaged one? We carry a large selection of components including 74HC Orders received and approved before 12pm PST will generally ship the same business day.
I have a feeling Q65, Q69 and Q78 maybe the reason why the robot will only go backwards seems like no datashee when going forwards.

To get price and availability information, fill out the RFQ form online and we will get back to you right away. Sine the wheel in reverse, is litterally giving off the dataaheet of an over revved engine kick back from top RPM as well as the bottom LED in BiT flashing.
It would appear that you datawheet now in need of a replacement PCA. Here’s my setup DSCF I’ve checked all components in the right wheel of the H datsaheet that are known, and replaced over 15 components and the wheel will not move forward.
We stand by all of our products and your satisfaction is our goal. Wheel has full current in reverse. All safety checks are inhibited during the BiTs so overcurrent would not stop the test.
Unless anyone has any ideas, I think I might just play around with it, watch it drive around in circles, keep my battery topped up and continues to find wtf is wrong. If you are careful you don’t need to worry about the battery voltage.

I’m open to ideas. Missing ground plane points will prevent the H-bridge from working correctly. We have loyally served our customers since I’m wondering, just datasheef the data sheets for 7hc140 diode used on the Right wheel, it’s a 1N, a shotkey diode. Charging works and fully charges the battery, but 5 744hc140 is all over the place when running on the battery.
With both IC’s replaced with no difference, it could rule out IC failure, which is a good thing.

I’ve tested so far DSCF. If specifications or datasheet needed – please contact the manufacturer of the product. What ever the fault is, I don’t think it’s the H-bridge.
