Look who is joining the maker community! Sony has showcased their Arduino compatible Spritzer board during the Maker Faire Tokyo on August 5-6. Despite lacking on-board network connectivity, the board is said to have been designed for IoT applications with features such as an integrated GPS and an advanced digital audio codec and amplifier.
- MCU – Sony CDX5602 ARM Cortex-M4F ×6 micro-controller clocked at up to 156 MHz with 1.5MB SRAM
- Storage – 8MB Flash Memory, micro SD card
- GNSS – GPS, GLONASS, supported
- Audio – 3.5mm audio jack
- Expansion I/Os
- Digital I/O Pins – SPI, I2C, UART, PWM ×4 (3.3V)
- Analog Pins – 6ch (3.3V range)
- Audio I/O – 8ch Digital MICs or 4ch Analog MICs, Stereo Speaker, I2S, CXD5247 audio codec with 192 kHz/24bit High-Resolution audio
- 2x camera interfaces
- USB – 1x micro USB port for programming
- Power Supply – Via Power barrel and Vin pin?
- Dimensions – Arduino UNO form factor?
In case you wonder why they bother to include GPS, but not WiFi or Bluetooth, that’s because the board is actually based on a Sony GPS chipset (CDX5602GF or CDX5602GG) that’s manufactured using FD-SOI process allowing for much lower power consumption. I don’t understand the meaning of “x6” in the specs, unless that’s an hexa-core Cortex M4F MCU, which I don’t think is possible.
The block diagram above does a decent job at explaining what’s feasible with the two chipsets used in the board. You’ll have to connect external module to get Bluetooth, WiFi, and LTE, a display up to 360×240 resolution can be used via SPI, all sort of sensors can be connected via the expansion header, the board is suitable for microphone arrays, and it can be powered by batteries thanks to a charger circuit and fuel gauge inside CXD5247 audio codec / PMU chip. The board can be programmed with the Arduino IDE and USB cable.
The company demonstrated the board the Maker Faire with a drone utilizing the GPS and the 6-axis sensor support, a smart speaker utilizing the audio functions, a self-driving line-tracing miniature car, and a low-power smart sensing IoT camera using the camera interface of Spritzer.
You’ll have to get patient before getting hold the board, as the Spritzer board is planned to be available for developers in early 2018. Visit the product page (in Japanese) for more details.
