BLE112-A-V1C 概要
A Bluetooth Low Energy module is a complete wireless subsystem that integrates a BLE radio, a microcontroller, an antenna or antenna connector, and a certified protocol stack into a single surface-mount package. Within the wireless hierarchy, it sits below full Bluetooth systems and above bare radio chips, allowing designers to add BLE connectivity without developing RF layout, antenna matching, or regulatory certification themselves.
Key features include Bluetooth v4.0 single-mode compliance, support for both master and slave roles with 4 or more simultaneous connections in master mode, and an integrated Bluetooth Low Energy stack covering GAP, GATT, L2CAP, SMP, and BLE profiles. The fully integrated approach combines radio, microcontroller, and software stack in one certified module, dramatically reducing development effort.
Technically, the module integrates the BLE radio transceiver with an on-board microcontroller running the Bluegiga Bluetooth Smart software, so host processors can communicate over a simple interface or the application can run entirely on-module. The U.FL connector permits an external antenna for optimized range and enclosure flexibility, distinguishing the -V1C variant from the chip-antenna BLE112-A-V1.
Typical applications include battery-powered sensor nodes, proximity beacons, fitness and health accessories, and industrial wireless monitoring where a Class 2 link with an externally optimized antenna is preferred. The 2 V to 3.6 V supply range allows direct operation from a coin-cell battery.
Design consideration: the U.FL variant requires a mating antenna assembly (U.FL to SMA pigtail plus antenna) in the bill of materials, and the 50-ohm transmission line to the connector should follow controlled-impedance layout practice on the host PCB.

主な用途
BLE112-A-V1C の用途: 6 件s: Battery-Powered Sensor Nodes, Fitness and Health Accessories, Bluetooth Proximity Beacons, Industrial Wireless Monitoring, Smart Home IoT Accessories, Embedded Systems Connectivity Add-On.
Battery-Powered Sensor Nodes
The BLE112-A-V1C fits coin-cell sensor nodes because its 2 V to 3.6 V supply range connects directly to a 3 V lithium cell without a regulator, and the integrated Bluetooth v4.0 stack handles GAP advertising and GATT services without host firmware. In a typical temperature or humidity node, the module spends most of its life in sleep and wakes for short advertising or connection events, preserving battery life. The U.FL antenna connector lets the designer place the antenna at the enclosure edge for optimal radiation even when the PCB sits inside a dense housing. Using the on-module microcontroller for sensing logic removes the need for a separate MCU, reducing BOM cost and sleep-state current.

Fitness and Health Accessories
Wearable health devices such as heart-rate straps and activity trackers benefit from the BLE112-A-V1C's small 32-pin SMD module format, Bluetooth v4.0 single-mode compliance, and integrated GATT profile support, which enables interoperability with smartphones and tablets. The certified stack including SMP provides the pairing and bonding security required for personal health data. The 2 Mbps air data rate covers streaming of sensor samples at typical physiologic rates, while BLE connection intervals can be relaxed between measurements to save power. The U.FL connector allows the antenna to be routed to a strap or case position with clear radiation, improving link margin when the wearable is worn against the body, which strongly attenuates 2.4 GHz signals.
おすすめ
Bluetooth Proximity Beacons
For iBeacon-style proximity applications, the BLE112-A-V1C transmits manufacturer-specific advertising packets using the integrated GAP layer, requiring only configuration firmware on the module's integrated microcontroller. Its 2 V to 3.6 V input suits direct coin-cell powering, a defining requirement for beacons deployed in quantity. The U.FL antenna variant is advantageous where the beacon housing is metallic or the antenna must be positioned for coverage, since a chip antenna near metal becomes detuned and loses range. Because the stack and radio are pre-certified, beacon deployments avoid per-design regulatory testing beyond the host product evaluation, and advertising interval and TX power can be tuned in firmware to trade range against multi-year battery life.
おすすめ
Industrial Wireless Monitoring
In industrial environments, the BLE112-A-V1C provides a Class 2 Bluetooth Smart link for machine-status sensors, meter readers, and condition-monitoring nodes that report periodically to a smartphone, tablet, or BLE gateway. Master mode with 4 or more simultaneous connections allows one module to act as a small local hub polling several nearby peripheral sensors, consolidating data before forwarding. The external U.FL antenna is valuable inside control cabinets, where the module PCB can remain inside while the antenna is mounted on the cabinet exterior for reliable 2.4 GHz propagation. The wide 2 V to 3.6 V supply range accepts standard 3.3 V industrial rails, and the certified stack with SMP supports secured pairing for plant-floor data integrity.
おすすめ
Smart Home IoT Accessories
Smart-home accessories such as door/window sensors, dimmer controls, and BLE-to-app configuration interfaces use the BLE112-A-V1C's integrated GAP, GATT, and profile stack so the product appears as a standard BLE peripheral to phones and home hubs without any host-side stack development. The single 2 V to 3.6 V supply works with both coin cells and 3.3 V house power. The module's integrated microcontroller can run the entire product application - debouncing switches, driving status LEDs, and managing sensor reads - eliminating an external MCU. The U.FL connector supports antenna placement optimized for whole-home coverage from a fixed installation point, and OTA-configurable advertising and GATT data let installers adjust behavior in the field.

Embedded Systems Connectivity Add-On
Designers adding Bluetooth Smart connectivity to an existing embedded product can use the BLE112-A-V1C as a certified wireless co-processor: the host MCU exchanges data with the module over its supported interface while the module's integrated stack manages advertising, connections, pairing, and GATT. This architecture avoids porting a BLE stack to the host and keeps RF expertise off the critical path, since radio, matching, and stack are integrated and pre-certified. The 32-pin SMD module reflows onto the host PCB like a standard component, and the U.FL output allows a pigtail to an external antenna placed clear of metal shielding. The 2 Mbps data rate and Class 2 power suit short-to-medium-range data exchange at low energy cost.

設計ノート
Route the U.FL antenna line as a controlled 50-ohm microstrip or coplanar waveguide from the module to the U.FL connector, keeping the trace as short as practical and referencing a continuous ground plane. Avoid routing the RF line under other signal layers or near switching regulators. Select a U.FL-to-SMA pigtail and antenna combination rated for 2.4 GHz, and secure the pigtail mechanically so repeated enclosure assembly does not stress the connector. Verify final radiated performance with a conducted or OTA test, since external antenna placement dominates real-world range.
Power the BLE112-A-V1C from a clean 2 V to 3.6 V rail; a 3 V coin cell or a 3.3 V LDO output are typical choices. Radio transmission draws burst current, so place low-ESR ceramic decoupling capacitors close to the module supply pins and ensure the source impedance of the supply (including coin-cell internal resistance) keeps the voltage above the 2 V minimum during TX bursts. Avoid long, thin supply traces from a shared rail; a dedicated decoupling network per the datasheet reference design prevents brownouts that manifest as BLE disconnections.
Do not substitute the -V1C (U.FL) footprint with the -V1 (chip antenna) without reviewing the mechanical design: a chip antenna requires a keep-out area free of copper and metal per the datasheet layout guidelines, while the -V1C requires clearance for the connector and pigtail. Also note that peripheral I/O pins lack internal pull-up/pull-down capability, so external resistors are needed where the application requires defined input levels. In power modes PM1, PM2, and PM3 the I/O pins retain their configured mode and output states, which designers should account for when computing sleep current.
