BTM42X Series
End of Life (EOL)
Overview
The BTM420/BTM421 Bluetooth modules are designed to meet the needs of developers adding robust, short range Bluetooth data connectivity to their products and using embedded Bluetooth stacks within these products. They are based on the market-leading Cambridge Silicon Radio BC04 chipset, providing exceptionally low power consumption with outstanding range. Supporting the latest Bluetooth Version 2.1 Specification with EDR (Enhanced Data Rate), HCI Data Modules increase data throughput up to 2.1 Mbps. BT version 2.1 provides the advantage of Secure Simple Pairing that improves security and enhances ease of use for end customers.
Note: The BTM420-xx and BTM421-xx variants have reached end of production and are available on a limited basis only. Find the End of Life Announcement in the Documentation tab below.
