if i connect power to the ez-b the leds don't light up. yesterday i had the same issue, and fiddled around a bit thinking there might be a loose connection. Randomly it did power up, but today i cant get it to work anymore. What could be the problem here, i cant see any obvious disconnections, how should i diagnose?
I removing my jack,one reason it sticks out,second can came out easy so best it use pcb mounted screw terminals
Problem solved, @Robot-Doc was right all along, but i was being stubborn.
It turned out that the pin from the heatsink was not well attached after all. Although i could not see this because it had come loose 'underneath' the droplet of solder on the back of the board.
I re-soldered just this pin from the heat sink, and all is working fine now. The part from the diagnostics video where i measured 1.3 instead of 5 Volt, is now properly at 4.98V.
Thank you!
yes that what i tought a gound was missing ,thats why you only read 1.3 volts its the reference voltage of the regulator . glad to see you got it fixed mostly grouds are are to find ,but easy to fix,loose ground or causes resets and more AT work when i design circuits i use whats called SPG single point ground same idea for robots also
