Introduction to TFT Proto 5”
TFT Proto 5” enables you to easily add a
touchscreen display to your design, whether
it’s a prototype or a final product. It carries
a
800x480 px
HT050AWV40T TFT screen
driven by a
SSD1963
graphic controller
that has an interface for 8/9/16/24-bit
MCUs. An
STMPE811
controller drives the
4-wire resistive touch-panel. The board
is lined with two rows of 26 pins with
16
data and 7 control lines
for the graphic
controller (including GPIO0 that accesses
the deep-sleep mode), plus
I
2
C lines and
an interrupt line for the touchscreen
controller.
The board uses a 3.3V power
supply only (with pins on each side of the
board added for convenience). Mounting
holes in each corner simplify integration.
