Ciao My card does not work anymore, the firmware is 2.3B5, the red led is on and the green one is off. I have the three axis board, but when i open the software does not recognized it. i have tried many ways to fix it like: with batteries on ,only 2 axis are working but the roll axis doesn't work. i think that there must be some series issues with the motor driver l6234d , but i am not sure.Do you think could be the atmel328 broken? or the motor driver? can anyone help me ?
As a last resort get a heat gun and very carefully apply heat to the board, on and off, this can resolve a dry joint even though the heat is not enough to melt the solder. You can also try this whilst the board is running (risky) and if you see a change in the status it will indicate a bad solder joint as it heats up then cools down.
Mine is due to shorting across 3rd axis pins and blowing up the reverse polarity chip. I replaced the chip and got the red light back but no green light.
Looks like I've blown my board too! Only red light and nothing else, steady green on 3rd axis board. Typically, we have a shoot next week and it's Chinese New Year so I'm stuffed! Will order a new one from RCTimer. I'll try and fault find but don't hold out much hope.
yes there are badly assembled boards out there with components that will falloff the board. so make sure you buy from someone with support for the product they sell
