Dimensions
The drawing below gives the primary dimensions of the 2x16 LCDs sold with our BPI-216N and BPI-
216L products. Three LCD manufacturers are listed, Truly, Data Vision (DV), and Powertip (PT), since
we have at times used LCDs from each of these companies. Powertip is our primary supplier.

BPI-216N/L is functionally identical to the previous
BPK-216N/L series. The main differences are in the
circuit-board layout, which in the BPI-216 has been
tailored specifically for 2x16 LCDs. The BPK-series is
a more generic layout, suitable for installation on
many LCD types. BPI-216N/L replaces BPK-216N/L,
but the BPK-000 (interface without LCD) is still
available. The table at right sums up the differences
between the two.
Feature BPK BPI
Interface board sold w/out LCD YES no
Backlight switch/series resistor no YES
LINES switch for 1-line LCDs YES no
Sold with LCD installed no YES
Low, < 1mA current draw (interface) YES YES
LCD-based serial protocol YES YES
Reversible 5-pin power/signal header YES YES

Important Notes on Handling, Installation, and Mounting
LCDs are precision-made devices that should last a lifetime of normal use. They are vulnerable to
damage from mishandling, however. Our warranty excludes damage from abuse, so it is very important
that you handle and mount your LCD with care. Here are some tips:
• Handle in a static-safe manner
• Do not drop or strike
• Do not attempt to disassemble, repair, or modify
• Do not drill, cut, notch, grind, etc.
• Mount with machine screws in corner holes
• Do not attempt to enlarge mounting holes
• Do not use glue, epoxy, or paint on this unit
• Protect from water, solvents, oils
• Do not bend, warp, or stress
• Install behind a protective transparent window
• Protect from strong electrical fields, ESD
• Protect from reverse-power hookup
