Is it a plug to use module? cause when i attempt to do so, there is no voltage at the output. is jumper wiring required to make this thingwork?
Is the chips being defective or its me..?
Hi again!Thank you for answering my question in the first place . I have selected the voltage ( 5v ), please refer to the attachment.There is still no power being supplied to the bread board... and the AMS1117 chips is smoking Is the chips being defective or its me..? the power being supplied to the Bread Board power module is from a 220VAC to 9VDC transformer. Any help will be appreciated! Thanks in advance! XDRegards,
If your 5V regulator is not burned up, it is damaged. You can see a burn mark on it in your picture. If it is working, it won't be soon. The fact that you have 3.3V selected and it is the 5V reg taking the hit would suggest it is something on the input to the 5V regulator (too high of a voltage) or a short after that. Connected to the 5V line are the LED, C2, C3, and the 3.3V regulator. I doubt the LED would blow it even if it shorted out since R1 would still limit current. C2 may be a crappy cap and shorted internally, or perhaps there is solder shorting out under C3. Finally, the 3.3v regulator may be shorted from Vin to GND. Unless they are using counterfit regulators, I would be surprised if the regulator is defective. I suspect the cap, C2. You could desolder it and see if things work with it removed. It is just a filtering cap and won't break the circuit with it removed (but might make the supply noisey.)
Yep. You can't even buy the regulators for that little. I guess I am glad I didn't order that model. I was actually just looking at those a couple weeks ago, but decided to buy mine from nkcelectronics instead which is 3.3/5V independently selectable for each rail (no on/off switch built in, though.) I like it.https://www.nkcelectronics.com/readboard-Power-Supply-Stick-Dual-Voltage-5V-and-33V_p_374.html
The AMS1117 had max voltage of only 10V, your 9V power adapter may output higher then 10V.http://www.sz-xiangshuo.com/en/templates/default/images/AMS1117.pdf

Mine is from AMS and yours is from "HotChip". Hahaha. Which is correct? Who knows.
