DemonstrationsFour iCE40UP5K-30WLCSP (U1-U4) devices are used on the Mobile Development Platform board. The devices areresponsible for specific demonstrations. Lattice provides separate user guides that describe each demo in detail. Thedocuments cover board configuration and step-by-step instructions. Please refer to the relevant documents for moredetails.The following sections describe the Mobile Development Platform board demos.6.1. Mobile Display Demonstration on U1This demo showcases the ability of iCE40 UltraPlus to drive a small wearable display and buffer one full image frame.Key components for this demo include: U1 iCE40UP5K-30WLCSP J2 Display connector for MIPI LCD display (MIPI LCD Display, 1.4” LH154Q01 is included in the kit.) U11 Display backlight driver U13 1.8 V and 3.0 V voltage regulatorNote: Be careful with the LCD display ribbon, it is fragile and can be damaged!6.2. Audio Microphone Demonstrations on U2FPGA U2 is optimized for microphone related demonstrations, such as audio beam. The board contains two I2Smicrophones, two PDM microphones, a 3.5 mm audio jack driven by a MAX9850 headphone audio amplifier, and anexpansion connector allowing up to seven microphones used in an array. This demo shows the capability of picking uphuman voice and driving the output on the speaker with the same quality, irrespective of where the voice is originatingfrom within a room.Key components for this demo include: U2 iCE40UP5K-30WLCSP U12/U19 I2S omnidirectional microphone with Bottom Port and Analog Output U94/U95 PDM omnidirectional microphone with Bottom Port and Analog Output U43 Audio DAC with headphone amplifier. J34 3.5 mm audio jack for analog output J15 Expansion connector supporting up to seven microphones. J25 Header used to configure FPGA to microphone connections6.3. RGB LED Demonstration on U3This demo showcases the capability of ICE40-UltraPlus to control and drive an RGB LED. A mobile app software GUI toolis provided to allow a user to remotely control the LED via a phone or tablet over Bluetooth. The features of the demoinclude: Ability to control the color of the LED from a color palette. Ability to control the brightness of the LED. Ability to control the ON/OFF time of the LED – thereby creating a pulsating breathing effect.Key components for this demo include: U3 iCE40UP5K-30WLCSP D13 RGB LED U30 Bluetooth Module used for remote control
