Product overview
Description
The STM32WL3x Nucleo-64 boards are based on the MB1801 mezzanine board and:
- The MB2029 MCU RF board for the NUCLEO-WL33xxx boards, featuring the STM32WL33CCV6 sub-GHz application processor (metering line; NUCLEO-WL33CC1 and NUCLEO-WL33CC2 order codes)
- The MB2339 MCU RF board for the NUCLEO-WL3Rxxx boards, featuring the STM32WL3RKBV6 sub-GHz application processor (remote control line; NUCLEO-WL3RKB1 and NUCLEO-WL3RKB2 order codes).
The high‑performance and low‑power application processors 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 NUCLEO-WL33xxx and NUCLEO-WL3Rxxx Nucleo-64 boards are supplied with a dedicated software package, HAL library, and various packaged software examples available with the STM32CubeWL3 MCU Package. They exist in two product variants with dedicated front ends tuned for specific frequency bands.
