The Sprint 2 board uses an Lm for a voltage regulator. LMT Regulator Circuit. Do not operate the unit s exceeding the absolute maximum rating, over rating causes damage to the units. Last edited by midelic; May 19, at It is not a shortcut,I think you exagerate Lab 9 in this note. Jsut on January 5, But the effect is that it is pulling up the output to 10v. In using them however you may notice it gets rather warm after a few minutes use, and even more so in sunlight.

In using them however you may notice it gets rather warm after a few minutes use, and even more so in sunlight. I am sorry but what do you mean? Originally Posted by dave lol. I never understood why the circuit was set up like that, but that makes sense. Be careful the diagram there is different Please review the schematic, more eyes the better. Documents Flashcards Grammar checker. B round pins are small it will not take much space.

The input is 9vac. Exposure of devices to any of these conditions may adversely affect long-term reliability. I have 3 module hooked right now on my arduino promini suplied from mA usb Originally Posted by midelic I think you made a confusion 1A 0. Remember Me Forgot Password? Tuesday September 22 written part. So initially I thought the regulator was bad, but I got a new one and the same problem is happening. Originally Posted by dave The receiver module needs 5V. This mod will allow the regulator to disipate the heat through the metal case and thus keep it cool, and make it more reliable.

This is due to the PCB having a 78H05 linear regulator on it which disipates the difference between a 3S lipo down to 5volts. LM System Power Management and. A minimum load of 10mA is recommended. Operation under no-load conditions will not damage these devices, however they may not meet all listed specifications.

That would make it 2. I will test with promini 8mhz if working fine we can use that one. That resistor basically bypasses the regulator. So what would be a good test load? What I would do is pull up the regulator and solder in a datasheet sBEC. No rights under any patent accompany the sale of any such product s or information contained herein.

Right now the regulated 5v supply is putting out 10v, which is the same voltage as the input to the regulator.
