3 Description
NINA-B221-02B and NINA-B222-02B have reached Initial Production status. These products
are pre-flashed with the u-connectXpress software version 3.0.0 and include new
functionalities and corrections associated with previous releases. Details about the software
can be found in the release note [4].
The hardware of each module has been updated with a new version of the ESP32 radio chip from
Espressif (part number ESP32‑D0WDQ6‑V3). The main difference between this later ESP32
version and the older chip version used in the NINA-B221-00B and NINA-B222-00B is a
correction in the secure bootloader ROM code. This correction resolves an issue that was
previously reported in the vulnerability reports CVE‑2019‑15894 and CVE‑2019‑17391.

First production parts are available for shipments now.
