Introduction
1.3.2
CY8CKIT-028-TFT board details
shows the TFT display shield that has the following features:
■
A 2.4-inch thin-film transistor (TFT) LCD module with 240 × 320 pixel resolution.
■
A three-axis acceleration and three-axis gyroscopic motion sensor.
■
A PDM microphone for voice input.
■
A 32-bit stereo codec with microphone, headphone, and speaker amplifier capability.
■
An audio jack with a provision of connecting both AHJ and OMTP headphones. The headset
standard can be set by an on-board switch.
