Which processor powers the EQM-EHL-B1?

It is built around an Intel Celeron SoC processor from the Elkhart Lake family, the same processor family used on the standard EQM-EHL module. The ordering options list Intel Celeron N6211 and Intel Celeron J6413 variants, both paired with onboard single-channel LPDDR4 8GB memory at 3200MT/s and rated for the standard 0°C to 60°C operating temperature range.

How does the EQM-EHL-B1 differ from the EQM-EHL?

Both are 70mm x 70mm Qseven modules built on Intel Elkhart Lake Celeron processors sharing similar I/O, PCIe, USB, SATA, and display capability. The EQM-EHL-B1 is the Rev. 2.1 B1 revision with onboard LPDDR4 8GB as standard and onboard eMMC 5.1 128GB, while the original EQM-EHL ships with 4GB onboard (hardware supports up to 8GB) and optional 64GB or 128GB eMMC.

How much memory does the EQM-EHL-B1 have?

The module has onboard single-channel LPDDR4 memory of 8GB running at 3200MT/s, soldered directly to the board. Because it is onboard memory rather than a socketed module, the 8GB capacity is fixed and cannot be user-upgraded after purchase, so buyers should confirm 8GB is sufficient for their application before ordering.

What storage does the EQM-EHL-B1 provide?

It comes with onboard eMMC 5.1 storage of 128GB, integrated directly on the module. There is no onboard SATA storage on the module itself, though the module's I/O includes 2 x SATA III interfaces that a carrier board can route to external drives for additional storage in the finished system.

What expansion options does the EQM-EHL-B1 support?

The module exposes 4 x PCIe x1 (Gen 3) lanes for expansion, along with additional low-speed interfaces including SMBus, LPC, I2C, SDIO, SD, and SPI. These are routed through the Qseven edge connector to a carrier board, such as Avalue's REV-Q703-B1 Mini-ITX evaluation carrier, which breaks them out to usable connectors.

What display interfaces does the EQM-EHL-B1 support?

It supports DP 1.4 or HDMI 2.0b, each up to 4096x2160 @60Hz, plus eDP 1.3 up to 4096x2160 @60Hz, and dual-channel 18/24-bit LVDS up to 1920x1080 @60Hz via an onboard Chrontel CH7511A/B eDP-to-LVDS converter. The exact combination available depends on the BOM/BIOS option selected, per Avalue's block diagram.

How many displays can the EQM-EHL-B1 drive at once?

The module can drive up to 2 independent displays simultaneously, selectable from its HDMI, DP, eDP, and LVDS outputs. This lets a single module support dual-monitor or dual-panel configurations in kiosk, HMI, or control-room applications without needing an add-in graphics card.

What is the maximum resolution supported?

Via DP 1.4 or HDMI 2.0b, or via eDP 1.3, the EQM-EHL-B1 supports resolutions up to 4096x2160 @60Hz. Via LVDS, resolution is capped at 1920x1080 @60Hz over a dual-channel 18/24-bit interface using the onboard eDP-to-LVDS converter. This flexibility lets integrators match panel resolution to the target display without changing hardware.

Does the EQM-EHL-B1 support LVDS panels?

Yes, LVDS output is supported up to 1920x1080 @60Hz over a dual-channel 18/24-bit interface, converted from eDP by an onboard Chrontel CH7511B chip. This lets integrators connect legacy LVDS industrial panels without a separate converter board, alongside the module's native DP, HDMI, and eDP outputs.

What networking does the EQM-EHL-B1 offer?

It includes one Intel I226LM Gigabit Ethernet controller providing a 10/100/1000 Base-Tx GbE compatible connection. This is the same LAN chipset used on the sibling EQM-EHL module, giving consistent driver support and network performance across both generations of the module.

How many USB ports does the EQM-EHL-B1 provide?

The module provides 1 x USB 3.2 Gen1 port plus 8 x USB 2.0 ports, routed through the Qseven edge connector. A carrier board determines how many of these are physically brought out to external connectors, so the number of usable ports depends on the chosen carrier design.

Does the EQM-EHL-B1 have serial/COM ports?

Yes, it exposes 1 x UART through the edge connector, which a carrier board can route to a standard RS-232/RS-422/RS-485 COM port depending on the transceiver fitted on that carrier. This is useful for connecting legacy serial instruments, PLCs, or industrial peripherals.

Does the EQM-EHL-B1 support SATA drives?

Yes, it provides 2 x SATA III interfaces via the edge connector, which a carrier board can route to onboard or removable SATA storage such as 2.5-inch SSDs or M.2 SATA drives, giving integrators extra storage beyond the module's own onboard 128GB eMMC 5.1 when the application needs it.

Does the EQM-EHL-B1 have hardware security features?

Yes, it includes an onboard TPM 2.0 chip for hardware-based cryptographic key storage, secure boot, and platform integrity verification. This is standard on the module rather than an optional BOM item, matching the TPM 2.0 support already available on the sibling EQM-EHL module.

What watchdog timer capability does the module have?

It has a hardware watchdog timer that can trigger a hardware reset, configurable from 1 second up to 65535 seconds in 1-second steps. This lets embedded software recover automatically from a hang or lock-up without requiring a manual power cycle, which is valuable in unattended industrial deployments.

What BIOS does the EQM-EHL-B1 use?

It ships with AMI uEFI BIOS stored in a 256 Mbit SPI Flash ROM. The same BIOS firmware also handles hardware status monitoring, tracking system temperature and voltage with auto-throttling control, helping protect the module automatically under thermal or electrical stress in embedded deployments.

What is the operating temperature range?

The standard EQM-EHL-B1 is rated for 0°C to 60°C (32°F to 140°F) operating temperature, the same standard range as the sibling EQM-EHL module. Storage temperature extends further, from -40°C to 85°C (-40°F to 185°F), for non-operating handling and transport conditions.

What humidity conditions can the module withstand?

It is rated for operation up to 95% relative humidity at 40°C, non-condensing, according to the published specification. This makes it suitable for humid industrial or outdoor-adjacent enclosures, provided the system design avoids condensation through proper sealing, ventilation, or heating where needed.

What power does the EQM-EHL-B1 need?

The module requires a +5V DC input and operates in ATX power mode. Actual current draw depends on the processor variant, memory, and peripherals connected via the carrier board, so system designers should size the power supply to the full carrier configuration rather than the module alone.

How much does the EQM-EHL-B1 weigh, and what are its dimensions?

The module measures 2.75 x 2.75 inches (70mm x 70mm), the standard Qseven form factor, and weighs approximately 0.095lbs (0.043kg). This compact footprint and light weight make it easy to integrate into space-constrained embedded enclosures such as thin panel PCs, gateways, or handheld industrial devices.

Which operating systems does the EQM-EHL-B1 support?

It supports Windows 10 and Windows 11 IoT Enterprise (64-bit), as well as Linux. This mirrors the OS support offered on the sibling EQM-EHL module, so software validated on one module family typically carries over to the other with minimal changes.

What certifications does the EQM-EHL-B1 carry?

The module is CE and FCC Class certified and RoHS compliant, confirming it meets applicable electromagnetic compatibility and environmental/hazardous-substance regulations. These certifications support deployment across commercial and industrial markets, including projects in India where TSL Automation supplies and supports the module.

How is the EQM-EHL-B1 mounted or integrated into a system?

As a Qseven module, the EQM-EHL-B1 mounts onto a carrier board through the Qseven edge connector rather than being used standalone. Avalue's REV-Q703-B1 Mini-ITX evaluation carrier board is listed as compatible, supporting the EQM-TWL, EQM-EHL, EQM-EHL-B1, and EQM-APL modules for development and evaluation.

Is a heatsink available for the EQM-EHL-B1?

Yes, Avalue lists a dedicated fanless heatsink, part number E1961211065012R, for the EQM-EHL-B1, with a 20mm height. It is specified for the standard-temperature SKUs built around the N6211 and J6413 processor options, providing passive cooling in typical embedded enclosures without added fan noise.

What ordering options are available for the EQM-EHL-B1?

Avalue lists two processor SKUs: EQM-EHL-N6211-B1R with the Intel Celeron N6211 and EQM-EHL-J6413-B1R with the Intel Celeron J6413, both configured with 8GB LPDDR4, 128GB eMMC, and the 0°C to 60°C standard temperature range. A matching carrier board and heatsink are also available separately.

What applications suit the EQM-EHL-B1?

Its compact Qseven form factor, integrated TPM 2.0, multi-display graphics, Gigabit Ethernet, and wide range of low-speed I/O make it suited to embedded and IoT designs such as industrial HMIs, kiosks, digital signage players, gateways, and compact panel PCs where a small, low-power x86 core is needed.

Can the EQM-EHL-B1 be used as a drop-in upgrade for the EQM-EHL?

Both share the 70mm x 70mm Qseven form factor, the same REV-Q703-B1 carrier board compatibility, and similar Elkhart Lake processor, display, PCIe, USB, and SATA capability, which supports compatibility at the carrier level. Designers should still confirm memory (8GB fixed vs up to 8GB) and eMMC configuration against their specific BOM before treating it as a direct swap.

Does TSL Automation provide warranty and support for the EQM-EHL-B1 in India?

Yes, TSL Automation Solutions is an authorised Avalue distributor in India and supplies, supports, and services the EQM-EHL-B1 locally. This includes manufacturer warranty coverage, technical assistance, and help with BIOS, driver, and carrier board integration questions for customers building embedded or IoT systems around the module.

How do I choose between the EQM-EHL and EQM-EHL-B1?

Choose the EQM-EHL-B1 if the application needs the full 8GB LPDDR4 and 128GB eMMC as standard, onboard TPM 2.0, and Qseven Spec Rev. 2.1 compliance out of the box. The original EQM-EHL remains an option where the base 4GB configuration is sufficient or where its optional 64GB eMMC variant better fits a lower-cost BOM.
