Description
The RN21 Bluetooth module is perfect for embedded
applications where the Bluetooth radio must be
located within a chassis. The small form factor and
external antenna allow the RN21 to fit into many
diverse applications. The straightforward hardware
interface, castellated pads and complete software
stack provides makes it easy and reliable to design
into your end product. The RN21 provides a low
power, high performance Bluetooth module that
supports multiple protocols, including Enhanced Data
Rate (EDR). The RN21 is the solution for developers
needing to add wireless capability to their product but
can not afford to spend significant time and money
developing Bluetooth specific hardware and software.
