TINY Bluetooth® Low Energy SoC and Module

Inside every Bluetooth sensor beacon is a System on a Chip (SoC) that’s a small computer that runs code. Dialog Semiconductor, the manufacturer of the SoC in some beacons, has just announced the world’s smallest (2.0mm x 1.7mm) and most power-efficient Bluetooth 5.1 SoC the DA14531.

The high level of integration means it only needs six additional electronic components and a power supply to make a complete Bluetooth low energy system. It’s expected to bring SoCs down to $0.50 in high volume.

While beacons tend to be limited by battery size rather than SoC size, the reduced price might bring downward pressure on cost. The small size is of more use in power harvesting/wearable scenarios such as printed Bluetooth sensors, connected injectors, glucose monitors and smart patches.

New ASensor Beacon

We have the new ASensor beacon in stock. This is our smallest sensor beacon measuring only 37.3mm x 37.3mm x 7mm and it uses the power efficient Dialog DA14580 that gives up to 1.5 years from a CR2025 battery.

The beacon supports iBeacon, Eddystone or sensor advertising. For sensor mode, the temperature, acceleration and battery level are in the advertising data.
