Bedrock V3000 Basic Tile

Bedrock is designed to address the diversity of requirements in the IoT space. This is achieved by partitioning the hardware into the following boards:

• SoM with the CPU, DDR5 and NVMe slots and all native interfaces on 380 pins of high density connectors.
• Networking and I/O board (NIO) with NICs and ports.
• Storage and Extension Cards board (SX) with slots for WiFi, 5G modem and extra NVMe devices.
• Power Module (PM) with DC to DC converter and DC input connector.

This modular design enables agile customization of Bedrock for addressing specific requirements. SolidRun is developing multiple NIO, SX and PM boards that can be mixed and matched as an off-the-shelf solution and also offers development of custom boards as an ODM service. Customers and 3rd parties that are interested in developing custom NIO, SX or PM boards are welcome to contact SolidRun for support. Bedrock enclosure is designed with customization in mind. Modification of I/O, power input, antenna openings etc. can be performed cost effectively even in small volume.

The compact footprint of Bedrock, robust structure, effective fanless cooling and DC input tolerance simplify Bedrock integration. All Bedrock I/O is brought to the front panel, with DC input and antennas in the top panel. The bottom and rear panel are both reserved for mounting, allowing full usability while Bedrock is mounted to a wall or to a desk. SolidRun offers multiple types of mounting brackets, including lever-based DIN-Rail bracket with locking, wall mount, small stand and ruggedised stand.

Field Usability

As a fanless, ventless IPC Bedrock requires no maintenance. Bedrock is designed to avoid the need to open it in the field. SIM cards are accessible from the panel using pin-hole trays. Remote power button connector is conveniently located on the top panel. All brackets and mounting fixtures are assembled from the outside. Should the need arise to open Bedrock (e.g. to install a storage device or replace the RTC battery) Bedrock opens by unscrewing a single screw.

The 0.6 Litre Bedrock Tile

When integrating an IPC in tight space convection cooling becomes ineffective and is better replaced with conduction cooling. It is also desirable to make the IPC as compact and thin as possible. Bedrock Tile is designed for these use cases. The ribbed chassis walls are replaced with flat walls with blind threadings for fastening Bedrock Tile to a cold plate. A key feature of Bedrock Tile is that it preserves the 360º internal heat distribution so it can be cooled from either side. With thickness of just 29mm and volume of 0.6 liter, Bedrock Tile is easy to integrate in tight spaces. Having all connectors on one side further simplifies the integration.

Advanced Integration Using Deck

Some integration scenarios call for custom enclosures (e.g. when additional devices must be installed with the computer in the same housing). To support these use cases Bedrock introduces the Deck concept (deck-of-cards). The SoM, NIO, SX and PM are rigidly held together with fasteners independently of the Bedrock enclosure. The Deck provides first stage cooling for most devices, in particular it includes a copper heat-plate on the CPU. The Deck is fastened to the custom chassis with only 3 screws. Fastening provides thermal coupling to the CPU, RAM, NVMe and FETs. The DC input connector is on wires and can be relocated in the chassis.

Designing with Bedrock SoM

Bedrock SoM makes a convenient and flexible building block for board designers. For many developers, using a SoM would be the only way to develop a computer based on AMD Ryzen™ Embedded V3000. Bedrock SoM makes an attractive platform for that purpose for several reasons. The SoM is far more self-contained than traditional SoMs. It has not only the essential CPU and RAM, but also NVMe, direct DC input with 12V – 19V tolerance and RTC battery. The SoM is provided in a ruggedized metal skirt that protects the SoM, provides mounting fixture for extension cards and serves as a heat-spreader for secondary heat sources. Copper heat-plate is pre-assembled on the CPU.
