NUCLEO-WL33CC2 [STMicroelectronics]

The STM32WL3x Nucleo-64 boards based on the MB1801 mezzanine board and MB2029 MCU RF board (NUCLEO-WL33CC1 and NUCLEO-WL33CC2 order codes) embed the STM32WL33CCV6 sub-GHz application processor. This high‑performance and low‑power application processor can operate in 433, 868, and 915 MHz bands.

The ARDUINO^® Uno V3 connectivity support and the ST morpho headers provide an easy means of expanding the functionality of the STM32 Nucleo open development platform with a wide choice of specialized shields.

The STM32WL3x Nucleo-64 boards are supplied with a dedicated software package, HAL library, and various packaged software examples available with the STM32CubeWL3 MCU Package.

The boards are declined in two product variants with dedicated front ends tuned for specific frequency bands.
