This board harnesses the power of a dual-core nRF5340 BLE SoC and combines it with the nPM1300 for peak efficiency.

It comes with 1M + 256 kB of flash memory and 512kB + 64kB of RAM, supporting complex applications. An additional 32 MB of external flash is accessible via the QSPI interface. An external 3.3V supply is efficiently managed by the nPM1300's load switch ⚡, ensuring maximum power savings.

Features:

• 128 MHz Arm Cortex-M33 + 64 MHz Arm Cortex-M33 - compare to nRF52840's 64 MHz Arm Cortex-M4
• 1M flash, 512kB RAM on application core + 256 kB flash, 64kB RAM on network core
• 32 MB of external QSPI flash
• 30% current consumption reduction as compared to the nRF52840 - source
• New nPM1300 PMIC w/ battery fuel gauge
• Integrated external 3.3V load switch to control external power draw
• Battery reverse polarity protection
  
• 800 mA max charging current
• USB D+/D- pads exposed
• RGB LED indicator controlled through nPM1300, firmware controllable to indicate charging, battery status
• Onboard reset button

N.B. will include pin headers.
