*Can'tSayThisOnTV*! Got a problem! Everything is hooked up but doesnt work. I found out that the 3.3v automatcially drops to 2.4 when i turn it on. And it stays like that even if i juice it up from the source.
The cart relocation is good. The screen works fine. I have tried 3 different jumper and expansion packs. Im 99% sure i havent fried it. Anyone got any ideas?
I ran into that with my first one and it normally had to do with the Texas Instruments chip not being soldered properly. It could be hooked up, but the pads on the chip don't like to stick to solder strangely enough. Also, I'm sure it is, but make sure you're battery is charged.
Thx. Cant be the ti chip though. As i dont use one. I have sturdy adjustable regulator which is very good. Ill try to charge my batteries. Maybe they have drained a little quicker than i thougt.
It seems like it's the regulator that's putting out less than it's supposed to - I don't know how adjustable regulators work, but I can assume that it's adjustable
If you need to, you could always get some free TI samples and try that out
Not so. Linear regulators work just fine, but they're inefficient and make a ton of heat. They work, but a switching regulator (like a pth08000) is more efficient.
