CY8CKIT-028-TFT Display Shield
Figure 4-6. TFT Display Shield
The TFT display shield has the following peripherals:
1.
2.4-inch TFT display:
This is a 2.4-inch TFT LCD module with 240x320 pixel resolution. This
display module is configured for an 8-bit parallel pinout connection to interface with the PSoC 6
device on the baseboard.
2.
Inertial Measurement Unit (U1):
This Inertial Measurement Unit (IMU) is a three-axis accelera-
tion and three-axis gyroscopic motion sensor that can be used to count steps to emulate a
pedometer or similar application.
3.
Ambient light sensor (Q1):
This is a high photosensitive NPN phototransistor IC that can be
used to detect intensity of ambient light.
4.
PDM microphone (U2):
This microphone converts voice inputs to pulse-density modulated
(PDM) digital signals.
5.
Arduino-compatible I/O header (J2, J3, and J4):
These headers interface with the PSoC 6
MCU GPIOs on the baseboard.
6.
Arduino-compatible power header (J1):
This header receives power from header J1 on the
board.
7.
Voltage regulator - 1.8 V (U4):
An LDO that converts 3.3 V to 1.8 V for the digital supply of the
audio codec.
8.
TFT display connector (J5):
This connector is used to connect the TFT display to the circuits on
the TFT display shield.
9.
Audio Codec (U3)
: This is a low power consumption, 32-bit stereo codec with speaker amplifi-
ers. The left channel and right channel amplifier output pins of the device are connected to the
on-board audio jack.
10.
Audio Jack (J6)
: The on-board audio jack provides a provision of connecting both AHJ and
OMTP headphones. The headset standard can be set by an onboard switch SW1.
