The Board
1 Application Examples
The GIGA Display Shield provides easy cross-form factor support for an external touch display, together with
several useful peripherals.
Human-Machine Interface Systems: The GIGA Display Shield can be paired together with a GIGA R1 WiFi
board for rapid development of a Human-Machine Interface system. The included gyroscope allows for easy
orientation detection to adjust the visual element orientation.
Interaction Design Prototyping: Quickly explore novel interaction design concepts and develop new ways to
communicate with technology, including social robots that respond to sound.
Voice Assistant Use the included microphone, together with the edge computing power of the GIGA R1 WiFi
for voice automation with visual feedback.

7 TFT Display
The KD040WVFID026-01-C025A TFT Display has a 3.97" diagonal size with two connectors. The J4 connector for
video (DSI) signals and the J5 connector for the touch panel signals. TFT display and capacitance touch panel
resolution is 480 x 800 with a pixel size of 0.108 mm. The touch module communicates via I2C to the main board.
The edge LED backlight is driven by the LV52204MTTBG (U3) LED Driver.
8 6-Axis IMU
The GIGA Display Shield provides 6-axis IMU capabilities, via the 6-axis BMI270 (U7) IMU. The BMI270 includes both
a three-axis gyroscope as well as a three-axis accelerometer. The information obtained can be used for measuring
raw movement parameters as well as for machine learning. The BMI270 is connected to the GIGA R1 WiFi via a
common I2C connection.
9 RGB LED
A common anode RGB (DL1) is driven by a dedicated IS31FL3197-QFLS2-TR RGB LED Driver IC (U2) which can
deliver sufficient current to each LED. The RGB LED Driver is connected via a common I2C connection to the GIGA
main board. An included integrated charge pump ensures that the voltage delivered to the LED is sufficient.
10 Digital Microphone
The MP34DT06JTR is an ultra-compact, low-power, omnidirectional, digital MEMS microphone built with a capacitive
sensing element and an PDM interface. The sensing element, capable of detecting acoustic waves, is manufactured
using a specialized silicon micromachining process dedicated to produce audio sensors. The microphone is in a
single channel configuration, with audio signals transmitter over PDM.

11 Power Tree
Arduino GIGA Display Shield Power Tree
The 3V3 voltage power is delivered by the GIGA R1 WiFi (J6 and J7). All onboard logic including the microphone (U1)
and IMU (U7) operate at 3V3. The RGB LED Driver includes an integrated charge pump which increases the voltage
as defined by the I2C commands. The edge backlight intensity is controlled by the LED driver (U3).
