Insert the leads into the tube boards, noting the markings, “Front,” and “Tube Other
Side,” when orienting the tubes.
Solder one lead of each tube first, then check the front to back and side to side
alignment. Then solder another lead 90 degrees from the first soldered lead, and check
again. If the alignment is correct, solder the remaining 20 leads.
Install two, 12 pin male headers on each tube board.
Step 3 – Final Assembly
Insert the eight RGB LEDs, LED1-LED8, into the board, but do not solder them in
place. Note the orientation. The long lead (or leads) go toward the dot on the solder
mask.
Insert each tube board into its corresponding female headers on the main board.
Turn the main board over, and adjust each RGB LED so that it is about 1mm below the
bottom of the IV-17 tube, then solder all four leads.
Install the microcontroller board, correctly orienting the USB connector and antenna,
with the markings on the board. Install the SD Card.
Install four, 10mm standoffs into the holes on the bottom of the main board, using four
screws.
This completes WordClock-3 assembly. Refer to the User Manual for setup and operation
instructions.
