Evaluates: MAX78000 MAX78000 Evaluation Kit General Description Benefits and Features The MAX78000 evaluation kit (EV kit) provides a platform Power Accumulator with Dedicated Display to Track for leveraging the capabilities of the MAX78000 to build Device Power over Time new generations of artificial intelligence (AI) devices. Onboard Digital Microphone Onboard hardware includes a digital microphone, a gyro- Onboard Accelerometer/Gyroscope scope/accelerometer, parallel camera module support SWD JTAG 10-Pin Header and a 3.5in touch-enabled color TFT display. A second- RISC-V Coprocessor JTAG 10-Pin Header ary display is driven by a power accumulator for tracking device power consumption over time. Uncommitted GPIO 16MB QSPI Flash as well as analog inputs are readily accessible through Select GPIOs Accessible through 0.1in Headers 0.1in pin headers. Primary system power as well as UART Four ADC Inputs with Optional AA Filter access is provided by a USB Micro-B connector. A USB to SPI bridge provides rapid access to onboard memory, Touch-Enabled, 3.5in, 320 x 240 Color TFT Display allowing large networks or images to load quickly.

This cable will power the board and provide a virtual serial port connection UART USB Bridge to the MAX78000 UART. The EV kit includes an FTDI FT230X USB-to-UART 5) On your PC, open a serial terminal application (such bridge chip. This eliminates the requirement for a physical as minicom or gtkterm), and connect to the virtual RS-232 COM port. Instead, the MAX78000 UARTs are serial port using a baud rate of 115200bps and 8-N-1 accessed through a USB Micro-B connector, CN1. UART settings. 0 and UART 1 are selected using JH1 and JH2, which also provide direct access to the MAX78000 UARTs, 6) Move the PWR switch to the ON position. bypassing the bridge chip.
