I purchased a Bareduino328 Plus. I is it not compatible with the Arduino Uno R3? I keep getting an error. The error says avrdude: stk500_getsync(): not in sync: resp=0x00 Any assistance would be appriciated.
Based on your description I am not entirely sure how you are trying to program the chip, but if you swap it with the Arduino Uno chip you will need to select Duemilanove W/Atmega328 as your device instead of Arduino Uno when you go to upload a sketch. You will also want to make sure you haven’t bent any pins by accident while inserting the chip.
If you are having that error while attempting to program externally you may have wired the Tx and Rx to the wrong pins or forgotten to wire the reset pin to your external set up, but either way let me know more details of your set up, and I will do my best to help you figure out what is going wrong.
