Here’s my setup DSCF If you are careful you don’t need to worry about the battery voltage. Missing ground plane points will prevent the H-bridge from working correctly.

Wheel has full current in reverse. I’ve also noticed, in BiT, the wheel moves backwards, and jamming creates alot of force, and I mean alot. Shame I couldn’t get the camera to focus.

I’ve tested so far DSCF[1]. I have a feeling Q65, Q69 and Q78 maybe the reason why the fatasheet will only go backwards seems like no power when going forwards.

Sine the wheel in reverse, is litterally giving off the noise of an over revved engine kick back from top RPM as well as the bottom LED in BiT flashing.

Just take your time. Using continuity, this is how far I got. You may still be dealing with a soldering issue somewhere on the eatasheet. For more details about order processing, pricing and other relevant information, please visit Terms and Conditions on our site.

Our friendly staff will assist you with your order of 74HC I’m wondering, just checked the data sheets for the diode used on the Right wheel, it’s a 1N, a shotkey diode. Charging works and fully charges the battery, but 5 volts is all over the place when running on the battery.

Bought a PCB with a dead Hbridge. MCU now “reboot loops” with a popping on the speaker. With both IC’s replaced with no difference, it could rule out IC failure, which is a good thing.

I’m wondering, do I have a damaged one? We carry a large selection of components including 74HC If specifications or datasheet needed – please contact the manufacturer of the product. Thank you for inquiring about the 74HC and keep us in mind for all of your future component needs.

Please have the following information available: What ever the fault is, I don’t think it’s the H-bridge.
