The 2621011024000 (Proteus-IV) from Wurth Elektronik is a Multi-Protocol Wireless Radio Module. It is designed for developers requiring a reliable, high-performance RF module that causes no hassles during firmware development, ensuring rapid time-to-market. This module is based on Nordic’s nRF54L15 SoC and includes a 128 MHz ARM Cortex-M33 processor with 1.5 MB Flash and 256 KB RAM, a security block, antenna selection, and serial/peripheral interfaces. It supports multiple wireless protocols - Bluetooth 6.0, IEEE 802.15.4, Zigbee, Matter, Thread, NFC, and proprietary 2.4 GHz. This radio module delivers a Tx output power of up to 8 dBm and a data rate of up to 4 Mbps.
The 2621011024000 (Proteus-IV) includes an SPP-like BLE profile that supports all 4 Bluetooth LE functions—central, peripheral, broadcaster, and observer and allows for smart antenna selection to achieve an optimum performance. This module uses a cryptographic accelerator with side-channel leakage protection, tamper detectors, secure boot, and secure firmware updates, resulting in high security. It can be controlled remotely using Global RTC, 14-bit ADC, and high-speed serial interfaces. This wireless module requires a DC supply of 1.7 to 3.6 V and consumes less than 10 mA of current. It is available in a WLCSP module that measures 12 x 8 x 2 mm.
