The PICO1TR-LED-CL is 43 LED board that is designed to interface with a
. The board size is 2.1" x 3.625" with a
the 2.1" x 1" area to mount a PICO1TR
The leds are arranged in an circular pattern. There are 42 LEDs arranged in rings
of 24, 12, 6 LEDs. The 43rd LED is in the center.
for the assembly instructions, schematic and bill-of-materials.
- 43 5mm LEDs -- requires only eight I/O lines.
- 2.1" x 3.625"
- Mounting area for PICO1TR.
- Positions for six 6mm pushbuttons (Panasonic PAE04M or equivalent).
- Position for a potentiometer (Panasonic EVU-F2AF30B54 or equivalent).
- 100mil Header connector for the unused I/O lines -- RX and TX
(PD0, PD1), digital I/O lines (PB3, PB4, PB5) and analog I/O lines
(PC0, PC1, PC2, PC3, PC4, PC5).
A drill template for the PICO1TR-LED-CL is available. The template
is designed to provide a center mark for all mounting holes, control
components and indicators. The center is indicated by a gap between
An easy way to drill multiple wood panels is to gang together the
panels and drill them all at the same time on a drill press. I mill
each panel to between 1/4" and 3/8", band them together and then drill
the group. To prevent blow-out of the bottom panel place a
To use the template to drill a wood panel --
- Print out the postscript file containing the template.
- Verify the print is 1:1 using the board measurements.
- Tape the template to a block of wood.
- Use a push-pin to mark the center of each hole.
- Drill the hole to the desired dimension. The diameters
indicated on the print are ≈ 10mils larger than the nominal
dimension of the component.
