PICO1TR-LED-S

The PICO1TR-LED-S is an 10x10 LED matrix that is designed to interface with a PICO1TR. The board size is 2.1" x 3.625" with a the 2.1" x 1" area to mount a PICO1TR. See the PICO1TR-LED-S datasheet for the assembly instructions, schematic and bill-of-materials.

Demo

The video (right) shows a PICO1TR mounted to a PICO1TR-LED-L LED matrix. By using Charlie-plexing the 10x10 matrix requires eleven I/O lines. The remaining nine ATmega168/328 I/O lines are free. The library used to create the example application has functions for driving individual LEDs, a row of LEDs and the matrix of LEDs. There is a Perl script that will convert an ASCII representation of the LED matrix to a C data file.

Drill Templates

A drill template for the PICO1TR-LED-S 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 the cross-hairs.

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 sacrificial panel underneath.

To use the template to drill a wood panel --
  1. Print out the postscript file containing the template.
  2. Verify the print is 1:1 using the board measurements.
  3. Tape the template to a block of wood.
  4. Use a push-pin to mark the center of each hole.
  5. Drill the hole to the desired dimension. The diameters indicated on the print are ≈ 10mils larger than the nominal dimension of the component.
