Schematics for the Jade Robot MAIN PCB. The Jade Robot is a tracked, differentially driven rover with: - OLED based, On board User Interface allowing the user to select different programs and options as well as develop simple programs for the robot - Dual, bi-directional motor PWMs signals for track movement - IR Based Object Detection/Ranging - Light Sensors - Audio amplifier with speaker - USB and Bluetooth interfaces - I2C based Expansion Slots - Battery Voltage Level Monitor - Control for bottom mounted sensors - PWM control for two servos - Digital camera (either 0706 or OV528 controller chips) serial interface This PCB is designed for +5V power with processor power reduced to +3.3V for the Freescale Kinetis MK20DN512M10 processor and peripherals. The Freescale Kinetis MK20DN512M10 is running an MQX RTOS application which access the following features in the MCU: - DI/DO Interfaces - ADC Inputs - Two I2C Buses (running at 400kHz) - One for the OLED and Audio Amplifier - One for Expansion Devices - Two UART Interfaces: - One for Digital Interface for Serial Cameras (Using the 0706 or OV528 controller chips) running at 115,200 bps or 921,600 bps - One for the BT Module, running at 921,600 bps - HID USB Interface - Five PWM Outputs - Two used for motor PWM (38kHz) - One used for IR Object Detection and Ranging (38KHz) - Two used for Servo Control (50Hz) - USB HID Interface at Full Speed (12Mbps) - .wav File Polyphonic Audio Output - Low Power/"Sleep" Mode for Extended Battery Life Component datasheets are continually updated, the latest datasheets can be found at the part manufacturer's web sites.
