u-blox USB-ANNA-B4 Evaluation & Demo Tools

u-blox USB-ANNA-B4 Evaluation and Demo Tools are built on the ultra-compact BLUETOOTH^® low energy SIP module ANNA-B4, based on the Nordic Semiconductor nRF52833 chip. These demo tools are evaluation boards with a USB stick form factor exhibiting a USB interface to simplify evaluation and prototyping directly from a PC. The USB-ANNA-B4 demo tools support the full BLUETOOTH^® Core specification v5.1 and IEEE 802.15.4 standards. These eval tools allow quick prototyping of a variety of extremely low-powered Internet of Things (IoT) applications. The USB-ANNA-B4 boards are available in two variants to accommodate alternative software solutions.

The USB-ANNA-B4 boards are available in two variants to accommodate alternative software solutions, viz., USB-ANNA-B402 and USB-ANNA-B412 boards. The USB-ANNA-B402 board includes an Open CPU ANNA-B402 module with an internal 2.4GHz antenna (integrated with the SiP).
The USB-ANNA-B412 board includes an ANNA-B412 module with pre-flashed u-connectXpress software and an internal 2.4GHz antenna (integrated into the SiP).
