1.1. About the Juno ADP

The Juno ADP is a 64-bit software development platform from ARM consisting of an ARM Versatile Express Juno Development Platform (V2M-Juno motherboard) and supporting firmware and software images.

The ADP is based around an ARMv8 Compute Subsystem (CSS) and provides:

  • Dual core Cortex®-A57 MPCore processors (big cluster).

  • Quad core Cortex-A53 MPCore processors (LITTLE cluster).

  • A Mali™-T624 series GPU with four shader cores for 3D Graphics acceleration and GPU compute.

  • A Cortex M3-based System Control Processor (SCP) which offloads power control and thermal management.

  • 4GB of DDR3-1600 memory (dual channel, striped).

  • An architecture that is aligned with Level 1 of the Server Base System Architecture.

  • ARM big.LITTLE MP support (hardware limitations apply in Juno r1).

The following hardware features are available only on Juno r1:

  • Peripheral Component Interconnect Express (PCIe) Gen 2.0 support.

The following features are not available on any Juno platform due to hardware limitations:

  • Intelligent Power Allocation (IPA) support.

Reference firmware and software images are available for the Juno ADP from Linaro.


The use of Juno software is subject to the terms of the Juno End-User License Agreement.

External interfaces include:

  • Support for LogicTile Express boards that you can use to extend the Juno ADP.

  • USB 2.0 and a custom SoC to Field Programmable Gate Array (FPGA) prototyping extension interface.


The V2M-Juno motherboard is lead-free.

The V2M-Juno motherboard is available from ARM. For information, see
