————————————————————
ATmega8 , PL-2302HX , TB6552 is assembled.

Assembling  from  low profile parts.  Be careful with parts polarity .

PCB is delicate, re-work is difficult, Please make sure correct assembly, or you will damage PCB.

-

1) resistor 330 (orange-orange-brown) or 1K (brown-black-red) 3pcs.

TESTING Board with PC .

- Download Scratch for NanoBoard.

- Install USB serial device driver,

Log-in PL2303 WEB site(User: GUEST, Password: GUEST)

proficdl0

  • Click  ”USB Serial/Paralell” on “USB Smart I/O controlers” menu at right side .

proficdl1

  • Click ”Drivers & Software” under PL2303 menu.

proficdl2

  • Download  Windows/Mac/Linux driver  middle of the web page
  • install dowinloaded module.

-

- Install? Scratch, then make connection with Scratch on your PC.

- NanoBoardAG LED will blink when you start Scratch connection.

- Please check “ScratchBoard watcher” , all sensor value should be displayed randomly.

At this point, you can check  MPU and USB  chip works fine. You do not finish sensor soldering yet , random value will be displayed.

-Exit Scratch software, then plug off USB connector.

-If something wrong, Please check parts position and POLARITY, and heat each solder-pad again.

-

Continue soldering.

10) CDS  float 5mm from PCB, solder one-pin , adjust assembly then solder another pin.

11) MIC

12) 47uF capacitor(small).  Check polarity, long lead(+) for white silk mark on PCB.

18)  slider 50K-B.

nbag11a-vr

両端の加工ができたら、基板に挿してみます。外側の足だけ合わない。

Slider pin does not fit with PCB hole.

その足だけを、根元から曲げる

bend slider pin to fit.

-

Finish solderling!!   take some rest, then check assembly again before Power ON.

- Install? Scratch, USB serial device driver, Then make connection with Scratch on your PC.

-

DC motor generate big noise, it makes problem with MPU and PC.

You need to put? three 0.1uF capacitor(included in kit) between motor pins, and motor body.

Pin header connector is useful for easy connection with connector cabling.  ( F.Y.I. )

The geared motor included in this kit is Low power type (5V 100mA). It works with USB power.

Please consider current restriction of moter driver (TB6552) spec , when you use other motor.
