I'm a complete newbie with Arduino. I've bought a couple of Nano clones from China. According to supplier description, it is Arduino Nano V3.0 ATMEGA328P ATMEGA328 CH340. Not sure why they list both 328 and 328P, but my struggle is to make it work anyway: IDE doesn't see it.
Power LED is on, L-LED is blinking regularly.
After some online reading, I conclude that the root cause may be in the USB-serial chip. My question is: if, when connecting this device to my Mac, I see a
/dev/tty.usbserial-1420 device appearing, does it mean that the USB-serial interface actually works correctly? Or does it not, and I should continue trying with installing some extra drivers etc.?
I am on Macbook Pro 2015, Mac OS 10.14.3. Many thanks in advance.
The error I am getting in IDE is:
avrdude: stk500_recv(): programmer is not responding
avrdude: stk500_getsync() attempt 1 of 10: not in sync: resp=0x00
Note: In a similar question the user didn't have the usbserial device in his /dev list.
