ALMA B2 series (Open CPU) Stand alone Bluetooth Low Energy (BLE) modules

u-blox has recently announced the ALMA-B2 standalone BLE 6.0 and 802.15.4 module family built around the Nordic Semi nRF54LM20 Cortex-M33 wireless microcontroller with a dedicated NPU for low-latency Edge AI applications. There are four specific product variants in the u-blox ALMA-B2 series: ALMA-B201, ALMA-B206, ALMA-B211, and ALMA-B216, all of which support Bluetooth 6.0 and Bluetooth Channel Sounding for distance measurement. They also support IEEE 802.15.4, including Thread, Zigbee, and Matter, as well as Nordic’s proprietary 2.4 GHz protocol and NFC. The company also mentions that the nRF54LM20B-based ALMA-B211 and ALMA-B216 variants include an Axon NPU that performs machine learning tasks up to 15 times faster and with greater energy efficiency than running the same tasks on the main processor alone. u-blox ALMA-B2 Series Specifications: Wireless SoC – Nordic Semiconductor nRF54LM20A (for ALMA-B201 and B206) or nRF54LM20B (for ALMA-B211 and B216) CPU Arm Cortex-M33 application processor clocked at up to 128 MHz RISC-V […]
