At Bay Area MakerFaire last week, STMicroelectronics and Arduino launched the STM32F469-based STAR Otto baseboard, which allows makers to build very high-performance processing and graphics into their smart devices for the Internet of Things. (STAR, which stands for ST and ARduino, is a collaboration between the two.)
The STM32F469 microcontrollers are based on the Cortex-M4 32-bit core operating at up to 180 MHz. The chip has a floating-point unit, a full set of DSP instructions, and a memory protection unit to enhance application security. The processor has 2 Mbytes of flash, 384 Kbytes of SRAM, and 4 Kbytes of backup SRAM. Included are the Chrom-ART graphics accelerator; three 12-bit A/Ds; two D/As; 12 general-purpose 16-bit timers, including two PWM timers for motor control; two general-purpose 32-bit timers; a true random number generator (RNG); and a crypto accelerator.
The STAR Otto board includes a microSD slot, Wi-Fi 802.11b/g/n, a MIPI DSI display interface, two MEMS digital microphones, headphone and speaker outputs, a USB Host interface, a camera connector, and Arduino Uno, Due, and Mega connectors.
DSI-display and NFC-reader shields are planned for the second quarter, and a sensor shield is scheduled to be available in the second half of the year. Pricing is not yet available.
