BT121-A-V1

Product Overview

BT121-A-V1 is a wireless connectivity RF module from Silicon Labs. The module adds RF connectivity to a host board while reducing the amount of discrete RF design work required in the end product. In a design or maintenance project, it is a candidate for Bluetooth Low Energy devices, beacons, sensors, wearable electronics, smart-home products and connected accessories.

Before design approval or replacement purchasing, check the 41-SMD Module package or case style, module-style construction for host-board assembly, RF layout and certification review. The antenna network, protocol stack, firmware version, power profile, regulatory requirements and lifecycle status should be matched to the original design or target application.
