Power supply method for Spresense main board
- Use the main board’s mico USB connector. (Also available to program) The micro USB port is recognized as a serial port by the PC.
- Connect a 5V±0.25V power source to the VOUT pin on the extension board, this is convinient when supplying power from another board. ※If you connect a power source with a voltage less than a range of 5V±0.25V, the main processor may be destroyed.
- If you are using the Spresense extension board the micro USB connector on the extension board can be used to power the system when the two boards are being used as a set. The micro USB port on the expansion board side is recognized by the PC as MSC (Mass Storage Class)
- The Spresense can be powered by a USB battery pack. For reliable USB battery pack operation choose a battery pack that has an “always on” feature or use a USB “keep-alive load”.
Edge AI system development
By linking with Sony’s Neural Network Console, it is possible to easily build edge AI systems that had been high hurdles until now. For those looking for full-fledged embedded development, the NuttX-based Spresense SDK lets you take full advantage of the power of Spresense.
