Quick Overview

The STM4100 is a generic Bluetooth to UART module, designed to quickly add wireless UART communications capability to any project.

Product Description

The STM4100 is a generic Bluetooth to UART module, designed to quickly add wireless UART communications capability to any project. The module is a truly integrated, plug-and-play solution, featuring a built-in low dropout voltage regulator, on-board ceramic antenna, and a unique low-profile connection, which gives the STM4100 several important advantages over SMT modules:

  • Can be installed one at a time to add wireless functionality to the host PCB
  • Easy to remove to repair or replace
  • More useable boards space on the host PCB: components can be placed under the module
  • Smaller financial investment (only buy as many modules as are needed in the short term)
  • Perfect to use for prototyping

The Tx output can be disabled by applying a logic HIGH to the Tx Enable pin, which makes it possible to have the target board switch automatically between the wired and wireless modes.
