Sony Spresense – The newest addition to the IoT development board family
IoT development boards come and go. For example, Intel quietly retired the Intel Edison board a while back. So, what it is the need for yet another IoT development board in the market, that too from a company which is not really seen as a part of the “Maker” ecosystem?
Sony released its Spresense IoT development board at this year’s Tokyo Makerfaire. It is quite interesting that Sony has decided to throw its hat on the IoT dev board market ring. The boards sold out pretty fast. So, may be Sony is doing something right here.
The main board uses a 6 core ARM Cortex processor with a clock speed of 156 MHz, but the key differentiating features are (1) The board comes equipped with Sony’s Global Navigation Satellite System receiver and high resolution audio codec. Sony clearly believes that positioning information and audio input/output would increasingly be important in IoT projects, going forward.
The board is designed to work with Arduino shields. In terms of the programming environment, you can get started with the Arduino IDE interface. But if you want to tap the full power and features of the Spresence, then you have the option of the extended API based on the NuttX SDK. You can also use the Scratch drag and drop interface to program the Spresence. Sony has announced plans to come out with with add-on modules like BLE, Camera and accelerometer sensors.
We, at MAKERDEMY, believe that the Spresense will be a solid addition to the IoT prototype boards and will be around for quite some time.
