Sony recently renamed its “old” Sony Spritzer, an Arduino compatible with a Sony hexa-core Arm Cortex-M4F micro-controller, a built-in GNSS receiver, and an audio codec.

They made some design modifications and called the “new” board Spresense. Sony is ready to launch the main board for ~$50, and the extension board for an extra $32 on July 31, 2018.

Sony released the specification of the development board with Arduino Uno connectors and support in Arduino IDE. Software can be developed using the Arduino IDE or the Eclipse IDE, and the board allows for the development of systems for diverse applications, including drones, smart speakers, sensing cameras and other IoT devices.
