Successful Guide to Single Sided S3V3 Severino !!!

remember the

avrdude: Expected signature for ATMEGA168 is 1E 94 06


the famous message
avrdude: stk500_getsync(): not in sync: resp=0x00
avrdude: stk500_disable(): protocol error, expect=0x14, resp=0x51

i've gotten both of them before!!

ok guys.

it was a success, after 7 days of F*king paranoia, sleepless nights. really.

LED13 blinks slightly (if you look hard) many times when uploading the bootloader / program.

i didn't connect the 2 pin jumper for AUTORESET.

i connected pin 2 & 3 for Serial Enabled jumper.

i plugged both the Parallel Programmer & DC Power Jack

both PowerLED & LED13 display light when connected to Parallel Programmer to PC.


    • burn bootloader first (using Parallel Programmer) at Arduino IDE 0017 => Tools/Burn Bootloader/w/ Parallel Programmer
  • and then program it serially (using USB to Serial cable; PL2303 prolific driver)
    • edit the preference.txt file, where as upload.using=parallel is used
  • this way, i didn't need to use bootloader. i can fully utilize 16kb of my Atmega168. Parallel Programmer works as an external programmer.

both methods were used also in serial.port=LPT1 set in preference file.


  • Windows XP
  • Arduino IDE0017
  • Tools/Board/Arduino NG or older w/ Atmega168

1st board (faulty, couldn't upload, i suspect due to poor soldering)

2nd board ( successful upload with both bootloader and programming )

better soldering, after much (hours and hours, relentlessly) practice!!!!

Lessons Gained :

  • electronics skills are very important.
  • extruding / protruding components legs should be cut before / after being soldered onto PCB, to avoid short
  • before soldering any god damn thing, on the newly etched PCB, all tracks are tested for short
  • when PCB is tested to be fine : no short, components are tested 1 by 1.

Reason for uploading this post :

  • i have been stumbling across too many scattered, different troubleshooting ideas. (and wasted tens of hours troubleshooting)
  • i also don't see any organized guide on the Severino.
  • i hope to help others making the Severino, as it is a much more economical Arduino version, thanks to Mr. Adilson Akashi of Brazil!

To chime in here. I really like this version of the board.

I've so far built 2 and each worked with no issues with the boards. (No, I'm not trying to rub that in.)

Some silly things I've done, however, was to have the wrong Serial Cable.

ya man. nice.
it's really cheap to make.
