FORT WORTH, TX / ACCESS Newswire / May 20, 2026 / Vadzo Imaging builds embedded imaging modules for vision systems. Today, the company launches the Bolt-521MRS. This is a 5MP NIR monochrome MIPI camera built on the Onsemi AR0521 BSI CMOS sensor. The Bolt-521MRS operates as a 5MP AR0521 rolling shutter MIPI CSI-2 camera. It delivers a full 5MP monochrome output with native near-infrared sensitivity and low-latency data delivery through a standard MIPI CSI-2 interface. Vadzo engineered this AR0521 NIR monochrome MIPI camera module to combine the sensor’s native NIR sensitivity with an ultra-lightweight 8-gram two-board form factor and a dual-configuration MIPI CSI-2 interface. The module is suitable for pathology, digital microscopy, medical device integration, industrial inspection, UAV payloads, and edge AI platforms. It connects directly to MIPI-based embedded single-board computers without custom carrier board development.

Sensor and Module Overview

The Bolt-521MRS integrates the Onsemi AR0521 BSI CMOS sensor with a native near-infrared monochrome imaging pipeline to deliver full-pixel NIR performance at the sensor level. The AR0521 is a 5MP (2592 x 1944) monochrome rolling shutter CMOS sensor featuring a 1/2.5-inch optical format and 2.2-micron pixel pitch. It captures full-resolution 5MP monochrome frames with native NIR sensitivity, no color filter array interference, and consistent edge definition under low-illumination conditions. Combined with a standard M12 lens mount and 2-lane and 4-lane MIPI CSI-2 interface, the module delivers full NIR monochrome performance at 8 grams without platform-specific hardware modification. That is why this AR0521 5MP NIR Mono MIPI Camera serves demanding embedded vision deployments across medical, industrial, and edge AI domains.

The Bolt-521MRS ships as an ultra-lightweight compact MIPI camera module. Inside: the Onsemi AR0521 sensor, a monochrome imaging pipeline, and a standard MIPI CSI-2 serial interface on a two-board architecture. The lens mount is S-Mount (M12). The module accepts any standard M12 lens, including NIR-optimized selections. The two-board design separates the sensor board from the interface carrier. Both 2-lane and 4-lane MIPI CSI-2 configurations are supported. The module operates immediately with Linux-based embedded platforms, including NVIDIA Jetson Nano, Jetson Xavier NX, Jetson Orin, and Raspberry Pi, using standard MIPI CSI-2 connectors and platform-native driver support.

Key Capabilities of the Onsemi AR0521 5MP NIR Monochrome MIPI CSI-2 Camera

5MP NIR Monochrome Sensor Architecture – Most embedded MIPI modules approximate near-infrared sensitivity through optical filters over color sensors. The Onsemi AR0521 captures a full 5MP (2592 x 1944) monochrome frame with native NIR sensitivity and a 2.2-micron pixel pitch. That means full photon budget per pixel at near-infrared wavelengths with no color filter array loss. Get 5MP spatial detail and NIR contrast that standard monochrome MIPI camera modules filtered from color sensors cannot match. This helps industrial MIPI camera deployments perform NIR-assisted surface inspection. It also helps low-light embedded camera systems extend operational hours beyond ambient illumination availability.

2-Lane and 4-Lane MIPI CSI-2 Interface – Most compact MIPI modules support only one lane configuration. The Bolt-521MRS supports both 2-lane and 4-lane MIPI CSI-2 configurations without hardware modification to the module. This 2-Lane MIPI CSI-2 and 4-Lane MIPI CSI-2 flexibility lets integrators match interface bandwidth to host platform constraints. This works for NVIDIA Jetson platforms with 4-lane CSI-2 availability and for Raspberry Pi platforms operating on 2-lane CSI-2 ports without redesigning the imaging chain.

Ultra-Lightweight 8-Gram Form Factor – Choose between standard and space-constrained OEM deployments with the Bolt-521MRS. The 8-gram two-board module fits handheld diagnostic instruments. UAV-mounted inspection payloads stay within the weight budget. Wearable industrial devices and miniaturized robotic vision assemblies integrate the module without custom mechanical adaptation. So, one 8-gram embedded camera handles pathology scanning, aerial inspection, robotic vision, and edge AI front-end tasks across a single production-validated assembly.

MIPI CSI-2 Platform-Native Integration – This embedded MIPI camera connects directly to any MIPI CSI-2 host port on NVIDIA Jetson Nano, Xavier NX, Orin, Raspberry Pi, and other MIPI-compatible embedded processors. No custom carrier board development is required. Platform-native Linux driver support makes the Bolt-521MRS operational from the first bring-up cycle. That saves time for machine vision camera teams, embedded vision camera system integrators, and NVIDIA Jetson Integration projects where schedule constraints make bring-up risk reduction the primary integration objective.

S-Mount M12 Lens Interface – The Bolt-521MRS uses a standard S-Mount (M12) lens holder compatible with the full range of commercially available M12 optics. Select NIR-optimized lens selections for pathology camera module slide imaging or wide-angle M12 optics for digital microscope camera assemblies. The M12 interface fits into tight OEM enclosures, including medical device camera housings, UAV payload bays, and wearable industrial inspection devices.

“The AR0521 sensor is known for its 5MP resolution and native near-infrared sensitivity without color filter interference. Many compact MIPI modules approximate NIR performance by filtering color sensors at the cost of resolution and per-pixel sensitivity. The Bolt-521MRS resolves this with a native monochrome pipeline. We built the AR0521 5MP NIR Mono MIPI Camera with an 8-gram two-board form factor and a dual-configuration MIPI CSI-2 interface. Now, pathology and UAV engineering teams get a module that delivers full monochrome NIR detail, spatial resolution, and platform-native MIPI integration through one validated assembly. That reduces integration complexity and moves production deployment timelines forward.” – Alwin Vincent, Product Manager, Vadzo Imaging.

Applications

Pathology and Digital Microscopy – For clinical slide imaging, tissue contrast analysis, and digital microscopy workflows, the Bolt-521MRS delivers 5MP monochrome NIR output over MIPI CSI-2. The AR0521 NIR monochrome camera module resolves tissue detail and slide contrast at the sensor level. Native NIR sensitivity eliminates color filter interference that reduces effective resolution in NIR-illuminated pathology environments.

UAV and Drone Imaging – Aerial inspection platforms need high-resolution monochrome NIR images for mapping and surface analysis. This compact MIPI camera module combines 5MP AR0521 NIR monochrome imaging with an 8-gram form factor to keep payload weight within UAV mass budgets. The MIPI CSI-2 interface connects directly to flight controllers or companion computers.

Industrial Inspection and Machine Vision – Industrial MIPI camera deployments and surface defect detection systems need full-pixel monochrome resolution and low-latency frame delivery under structured NIR illumination. The Bolt-521MRS delivers 5MP rolling shutter output over a low-latency MIPI CSI-2 data path. Low-latency MIPI delivery handles inline measurement cycle times that USB-based camera architectures cannot meet.

Medical Device Integration and Portable Diagnostics – Diagnostic instruments and portable medical imaging assemblies require high-resolution monochrome imaging with tight weight and power constraints. The Bolt-521MRS medical device camera delivers 5MP NIR monochrome output at 8 grams with M12 lens compatibility. NIR sensitivity supports tissue imaging under active IR illumination. MIPI CSI-2 integrates directly with embedded medical device processors.

Embedded Edge AI Inference – Autonomous robotic platforms and edge AI deployments need high-resolution NIR monochrome input delivered over a native interface with no USB buffering overhead in the imaging pipeline. The Bolt-521MRS embedded vision camera feeds NVIDIA Jetson and Raspberry Pi platforms with full 5MP monochrome sensor data over validated MIPI CSI-2 at up to 30fps. One module handles navigation, inspection, and analytics inference tasks without platform redesign.

Robotics and Autonomous Systems – The AR0521 sensor’s 5MP resolution and native NIR sensitivity help robotic vision assemblies capture fine spatial detail and surface contrast without colour filter loss at near-infrared wavelengths. That supports visual serving, part identification, and robot guidance at consistent working distances. The machine vision camera module operates at up to 30fps at full 5MP resolution over MIPI CSI-2. Platform-native driver support on NVIDIA Jetson enables same-day bring-up without kernel customization.
