ATSAMB11-MR210CA Обзор
A Bluetooth Low Energy module is a pre-certified subsystem that bundles the radio IC, baseband, protocol stack hooks, and antenna into a single reflow-solderable package, allowing designers to add wireless connectivity without having to design an RF layout or navigate RF regulatory certification. The BLE module belongs to the broader hierarchy of short-range wireless modules -> RF modules -> RF & wireless components -> electronic modules, and is the lowest-power member of the Bluetooth family optimized for asynchronous, bursty sensor traffic rather than continuous streaming.
Key features include BLE 4.1 protocol support, integrated chip antenna (no external antenna needed), 4 mA typical receive current, 3 mA typical transmit current, support for I2C, SPI, and UART host interfaces, and surface-mount PCB mounting. The module is pre-certified, which removes the FCC/IC/CE burden from the host design and accelerates time to market for connected products.
Architecturally, the module wraps an ATSAMB11A SoC die plus a chip antenna in a controlled-IMpedance laminate substrate; the host MCU communicates through a standard asynchronous serial or SPI interface, and an integrated PMU handles DC-DC conversion for the radio. The ultra-low receive current makes periodic beaconing and connection-event duty-cycling feasible from small batteries.
Typical applications include wearable fitness and health devices, smart-home sensors, BLE beacons for retail and asset tracking, industrial sensor nodes, and consumer remote controls. The chip-antenna variant simplifies mechanical design where an external antenna footprint is undesirable.
Designers should treat the module as a black-box radio: provide a clean 2.3-3.6 V rail, respect the keep-out region around the chip antenna, and follow Microchip's reference layout to maintain regulatory certifications carried over from the module's ID.
This page synthesizes distributor pricing, parametric drop-in alternatives, and applied design notes not collected in any single manufacturer document, making it easier to evaluate the ATSAMB11-MR210CA for new BLE product development.

Типичное применение
ATSAMB11-MR210CA подходит для 7 применениеs: Wearable Fitness and Health Devices, BLE Beacons for Retail and Asset Tracking, Smart Home Sensors, Industrial Sensor Nodes, Consumer Remote Controls, Connected Toys and Hobby Electronics, Medical Monitoring Accessories.
Wearable Fitness and Health Devices
The ATSAMB11-MR210CA's 4 mA RX and 3 mA TX currents and integrated chip antenna make it a strong fit for wrist-worn fitness bands and health patches that advertise BLE GATT services to a paired phone. The 2.3-3.6 V supply range allows direct connection to a single CR2032 coin cell, while the pre-certified module removes the FCC/IC/CE burden that would otherwise block a low-volume wearable launch. Designers pair the module with a host MCU running heart-rate or step-count algorithms and stream results over standard BLE notify characteristics.

BLE Beacons for Retail and Asset Tracking
The ATSAMB11-MR210CA is well suited to iBeacon/Eddystone beacon hardware where the module advertises at sub-second intervals and spends most of its life in low-power sleep. The chip-antenna variant eliminates the external antenna BOM, reducing beacon tag cost and simplifying mechanical integration into retail displays or asset-tracking labels. With typical TX current of 3 mA and a small coin cell, multi-year beacon lifetime is achievable on standard duty cycles.
Рекомендуется
Smart Home Sensors
Door/window sensors, temperature/humidity nodes, and occupancy detectors benefit from the ATSAMB11-MR210CA's low duty-cycle current profile and small module footprint. The host MCU wakes the BLE module only when an event must be reported, allowing coin-cell-powered smart-home nodes to operate for years without service. The integrated chip antenna keeps the BOM to a minimum - critical for cost-sensitive consumer smart-home products.
Рекомендуется
Industrial Sensor Nodes
In factory-automation contexts the ATSAMB11-MR210CA enables wireless retrofit of legacy sensors without running new cabling. Its surface-mount package and pre-certified RF section accelerate panel-mount sensor designs that previously required wired interfaces. Note that Microchip has marked the part obsolete, so industrial designs should plan for the SAML21 + BM71 migration path documented in Harmony 3 collateral for new product introductions.
Рекомендуется
Consumer Remote Controls
Voice, gesture, or simple button remotes increasingly use BLE rather than infrared to support two-way pairing, battery telemetry, and direct smartphone control. The ATSAMB11-MR210CA's 2.3-3.6 V supply works directly from two AAA cells, and its integrated chip antenna eliminates the whip antenna that would clutter a slim remote housing. Designers can implement HID-over-GATT profiles for media control and BLE pairing for setup.
Рекомендуется
Connected Toys and Hobby Electronics
Educational electronics and hobbyist BLE projects benefit from the ATSAMB11-MR210CA's small surface-mount footprint and pre-certified radio, which lets a maker avoid FCC testing for prototypes. The module pairs with phone apps over standard BLE GATT services, making it a quick path to interactive BLE demos, robotic controllers, and classroom kits. Designers should plan for EOL supply given the obsolete lifecycle status.
Рекомендуется
Medical Monitoring Accessories
Patient-side monitoring accessories such as pulse-oximeter pods, thermometer patches, and medication-adherence sensors can leverage the ATSAMB11-MR210CA's ultra-low receive current and integrated chip antenna. The BLE 4.1 GATT profiles are widely supported by medical gateway apps on iOS and Android. Designers must perform their own regulatory validation for medical claims and should confirm supply availability given the obsolete status.

Заметки по проектированию
Maintain the manufacturer-specified keep-out zone around the chip antenna. The integrated antenna's RF performance is tightly coupled to the absence of copper planes, traces, and components in the keep-out region documented in the SAM B11-MR210CA/MR510CA datasheet. Violating this region detunes the antenna, reduces range, and may invalidate the module's regulatory certification ID carried over from the original test setup.
Provide a clean 2.3-3.6 V rail with at least a 1 uF decoupling capacitor near the module's supply pins. Although the internal PMU regulates this rail for the BLE SoC, transient loads during TX bursts can pull the input down; insufficient decoupling can cause dropped packets or module resets. For coin-cell designs, account for the battery's internal resistance under pulsed load when estimating usable capacity.
Estimated: assume roughly 1.5 uA average current draw for a 100 ms connection event every 1 s at 0 dBm TX power, giving roughly 6 months of life on a 240 mAh CR2032 - verify with your actual duty cycle. Many BLE designs underestimate the cost of long advertise intervals; pre-test with the manufacturer's power-calculator tools before committing to battery capacity. Because the ATSAMB11-MR210CA is now obsolete, lock in last-time-buy supply before launching new products.
Treat the module as a pre-certified RF subsystem - use the manufacturer reference layout verbatim, including module orientation, ground plane treatment under and around the module, and host-connector placement. For new designs consider migrating to the SAML21 host MCU plus BM71 BLE 5.0 module, as Microchip's current collateral recommends this path over the legacy SAMB11 modules.
