Jupiter Nano

Jupiter Nano is a small ARM-based development board based on the SAMA5D27C-LD1G that runs Linux or the Apache NuttX Real Time Operating System.

Hardware Information

  • Runs NuttX RTOS or Linux: Das U-Boot open-source boot loader works for Linux and NuttX (or Linux can be booted directly); bare-metal capable using Microchip libraries and tools.

  • Size:

    • 48-pin form factor

    • 2.86 cm x 6.35 cm (1.125” x 2.5”)

    • Similar in size to Teensy 4.1

  • Programming: JTAG port for programming and debugging

  • CPU: Microchip SAMA5D27C-LD1G running at 498 MHz

  • DRAM: AP Memory AD2100XXX 128 M x 32 LPDDR2 DRAM chip integrated into system-in-package (SIP)

  • Power management: Qorvo ACT8945A with integrated LiPo battery charging capability

  • Power delivery: Compatible with many LiPo batteries

  • Open Hardware: Design can be altered using 100% open source KiCAD software

  • 10x more powerful than the Arduino Due:

    • ARM Cortex A5 processor running at 498 MHz (7x the clock speed of an Arduino Due)

    • 128 MB RAM (1280x the RAM of an Arduino Due)

    • Key peripherals (USB, SPI, I²C, Flexcom) support DMA

  • I/O:

    • USB 2.0 High-Speed port on USB Micro B connector (Port A, 480 Mbps, host or device)

    • USB 2.0 High-Speed port on a pin-header connection (Port B, 480 Mbps, host only)

    • USB 2.0 Full-Speed debug console port on USB Micro B connector (12 Mbps)

    • Micro SD Card slot (50 MHz DDR) supports booting from removable storage, making it impossible to brick the device

    • Native SPI, TWI, CAN, and I²SC ports

    • 4 FLEXCOMs on I/O pins – flexible serial controller peripherals that can be SPI, USART, or TWI
