Step 2. Place TB6612 H-Bridge board, IC side down. Pin 1 is PWMA
Step 3. Get Main PCB from Mr J. Pictured below
Step 4. Place (2) 14 pin SIP headers as shown, notice the the headers will not stay in place
Step 5. Place TB6612 H-Bridge board in the bottom most rows of the SIP. This will hold the SIP sockets in place so you can solder and keep pins aligned.
Step 6. Solder the four corners of the SIP Sockets, then check alignment.
Step 7. Once alignment passes, solder the rest of the pins on the SIP socket, with sharp diagonal cutters cut the LEFT SIP socket Flush to PCB. This will help the battery clip lay flat.
Step 8. Place Battery clip. And solder on the componet side of the PCB shown below
Solder POS lead
Solder NEG lead
Step 9. Unplug the TB6612 H-Bridge board and put aside. Get a BT board from Mr. J, Desolder the pins. They are facing the wrong direction
De-soldered BT Board
Step 10. Place straight 6 pin SIP, as show below, long side of the lead facing down, short side of lead plugs into board.
Step 11. File the top of the TB6612 H-Bridge board about 20 strokes, mileage mat vary. This will trim the board do it can fit next to the BT board.
Step 12. File the side of the BT board towards the SATE pin about 20 strokes, mileage mat vary. This will trim the board do it can fit next to the TB6612 H-Bridge board .
Step 13. Plug TB6612 H-Bridge board back in
Step 14. Get a 6 pin Right angle SIP connector
Step 15. Place the 6 pin Right angle SIP connector on the top right hand side on the SIP socket, this is to connect your (2) motors later.
Step 16. Plug BT board in the top left hand side on the SIP socket. If tight fit refile the boards to fit.
Step 17. Place the 6 pin Right angle SIP connector on the top left hand side of main board, this is the programming header.
Step 18. Get (2) glass beads and 16 Mhz crystal
Step 19. Place glass beads on to crystal leads, this will insulate the crystal from the top layer solder pad
Step 20. Solder in crystal, make sure the glass beads are on the leads.
Step 21. Insert (2) 22pF capacitors and solder them in
Step 22. Insert 10K ohm resistor next to Pin1 of the IC, Solder in place.
Step 23. Insert .1uF (labelled 104) capacator next to Pin 1 of the IC, Solder in place.
Step 24. Insert (2) 470 Ohms resistors, Solder in place.
Step 25. Insert LED, Long lead (+) faces the IC socket, Solder in place.
Step 26. Insert 3 pin SIP into the servo position, Solder in place.
Step 27. Insert 22uF SMT Capacitor and remove right angle SIP
Step 28. Plug in BT board
Step 29. Get (2) .01uF (labeled 103) capacitors for draw A35 in the parts room, cut one lead of the cap short.
Step 30. Thread cap though tab on motors, solder
Step 31. Cut leads flush with motor tab
Step 32. Add red/black STRANDED twisted wire (6" long") to each motor Look for the + symbol on the motor attach the red wire to this.
Step 33. Place Right angle header in helping hands
Step 34. Strip, tin and solder on the short side as shown below.
From left to right No Connection, No Connection, -M1,
Step 35 Inspec and plug into main board, motors toward bottom edge.
