Our best-selling PiTFT just got a fancy upgrade, now we have a version
with a capacitive touchscreen! That's right, instead of a resistive
touchscreen, which requires a fingernail or stylus, you can now use a
fingerpad. The screen looks much nicer, with a black bezel and glass
Featuring a 2.8" display with 320x240 16-bit color pixels and a
single-touch capacitive touch overlay. The plate uses the high speed
SPI interface on the Pi and can use the mini display as a console, X
window port, displaying images or video etc. Best of all it plugs
right in on top!
It's designed to fit nicely onto the Pi Model A or B rev 2 but also
works perfectly fine with the Model B+ as long as you don't mind the
PCB overhangs the USB ports by 5mm. Model B rev 1 have an older layout
for the I2C pins and won't be able to use the touch screen
Uses the hardware I2C Pins (SDA & SCL), SPI pins (SCK, MOSI, MISO,
CE0) as well as GPIO #25 and #24. All other GPIO are unused and you
can still share the I2C pins with sensors, LED drivers, etc. Since we
had a tiny bit of space, there's 4 spots for optional slim tactile
switches wired to four GPIOs, that you can use if you want to make a
basic user interface. For example, you can use one as a power on/off
button. See below for the link to get the optional tact switches,
they're not included.
The screen is the same size as the resistive type so you can use this
with the PiTFT PiBow or any other enclosure you may already have. We
also use the same SDL device and signals so PyGame and X11 based
programs can be swapped in with no changes in code.
This version comes as a mini-kit, with a 2x13 extra-tall female header
(to connect the plate to the Pi) and a 2x13 male header that can be
used to connect an IDC cable or cobbler from the side. The photos
above also show the installed slim tactile buttons. Here at Play-Zone,
the tactile buttons are included and do not need to be bought
seperately! Some basic soldering is required to install the headers.
