Jupiter Nano

This repository contains the KiCAD hardware design files for the Jupiter Nano.

This is a small Open Source Hardware board based on the Microchip SAMA5D27C-LD1G microprocessor. It runs Linux and the Apache NuttX Real Time Operating System (RTOS).

Status

This board is in production and works.

CERN-OHL-S (Strongly Reciprocal). For more information, see the LICENSE file in this repository, or the CERN Open Hardware License v2.0 page.

Runs NuttX RTOS or Linux: U-Boot open-source boot loader works for Linux and NuttX (or Linux can be booted directly)
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
