Bedrock SOM

Introduction

This user manual is intended to assist board-designers who consider developing a custom NIO for SolidRun Bedrock SOM.

Bedrock SOM

Bedrock SOM is a system-on-module based on AMD Ryzen Embedded / Mobile processors with FP7R2 footprint. It is a compact self-contained computer system with processing, RAM, storage, power regulation and cooling. It brings out only the native I/O of the processor through high density board-to-board connectors to allow highly-modular system design with a high-degree of system customization by extension boards.

Currently Bedrock SOM is offered with several Ryzen variants including

• Ryzen Embedded V3000 series

• Ryzen Embedded 8000 series (“Hawk Point”)

• Ryzen 7000 series (“Phoenix”)

To learn about the unique properties of each processor please review the corresponding Bedrock PC documentation.

NIO - Networking & I/O Extension Board

NIO stands for Networking & I/O. NIO extension board is connected directly to Bedrock SOM.

SolidRun offers several types of NIO boards. NIO design files are offered as reference for board-designers who considering developing custom NIO boards.

About this User Manual

This manual will guide you through the key aspects of integrating Bedrock SOM into your custom NIO design. It covers essential design considerations, including power requirements, signal integrity, thermal management, and connectivity options, ensuring you can fully harness the power of the AMD Ryzen™ processor in your specific application.

Each section of this manual provides detailed information and technical specifications to help you understand the interfaces, pinouts, and schematic design principles necessary for successful integration. Additionally, we provide best practices and expert tips to mitigate common design challenges and optimize your development process.

Bedrock Cartridge

As part of developing a custom extension board for the Bedrock SOM, it’s recommended to use Bedrock Cartridge.

Bedrock Cartridge provides the following:

• Highly effective 1st stage thermal coupling (TIM0) to the Ryzen die to a copper heatplate.
  Coupling the heatplate to a heatsink/cold-plate is easy. Coupling the die is challenging.

• Provision for mounting NIO securely with accurate spacing.

• Easy mounting of SOM to enclosure / heatsink / cold-plate.

• Thermal coupling for SOM’s DC-to-DC converters

• Mounting of NVME SSD
  Not present on SOM itself

• Securing and thermal coupling for SODIMMs

• RTC battery compartment

• Physical protection and rigidity to the SOM

• Rigid chassis for the Bedrock Deck with multiple threaded mounting holes

SOM Board-to-Board Connectors - MFG P/N

Bedrock SoM Connectors (Males):

NIO Connectors (Females):

Note: Top Side of SoM is placed on Top Side of NIO, where the two boards are flipped one towards the other.

Board-to-board Connectors Pin-out

The following is an example of the B2B pinout in NIO.
Please note that the pinout relates to the female connectors on a carrier, to which the Bedrock SoM male Connectors are inserted, and here we gave an example for SolidRun NIO Connectors (J4, J5, J6, J7). It’s important to be careful which pin is number #1.
