appears to work well, I will not be using to receive more appropriate

what type of smd is?

thank you so much guys for every help.



I check the orange tx 433

I understand have damage from overvoltage, i think these module only work with 5V, is correct? and when measured the turnigy 9x gives the same voltage as the battery

The "voltage section" in orange 433 is ok the atmel 328 have 3.3v, the atmel is very very hot, i can not program bootloader

I think the ATmega328 is damaged what do you think?

Hi,
I know that this is an old thread but I just wanted to say thank you to MikeB, I followed your instructions for checking the voltages to each pin replaced Q2 and R9 and I now have a working transmitter. Thanks once again Marty

2512 is R100 but at what K 100K 200K?
I tried to pm mike. Pm if you see this please. And any others I should order for back up.

Nice thread but no one seems to answer the question.
What smd is r9 R100 ?
Above is it but at what K is the question. Yes bypass is easy but a fix or perma fix with out losing function for same effort is no brainer.

Thanks.

R9 is a current sense resistor, 0.1ohm 1% 1/4W. The 'R' of R100 represent the decimal point so is .100 ohms.

This is another excellent thread!

THANK YOU! to Sir Technicus Genius for another great hint to diagnose and fix things quickly and easily!

I was asked for help to repair a 9XR PRO which stopped working after the RF module connector got somewhat short... Yes, it was the R9 that failed. All other parts seem Ok, and the radio runs fine once the R9 is replaced.

Thanks a lot, Mike!!!
