Description
The RN-42 is a small form factor, low power, class 2
Bluetooth radio for designer’s who want to add wireless
capability to their products. The RN-42 supports
multiple interface protocols, is simple to design in, and
is fully certified, making it a complete embedded
Bluetooth solution. The RN-42 is functionally compatible
with the RN 41. With its high-performance, on-chip
antenna and support for Bluetooth EDR, the RN-42
delivers up to a 3 Mbps data rate for distances up to 20
meters.
The RN-42 is also available in a package without an
antenna (RN-42-N). Useful when the application
requires an external antenna, the RN-42-N is shorter in
length and has RF pads to route the antenna signal.
