STMicroelectronics STM32WL3x Development Boards
STMicroelectronics STM32WL3x Development Boards combine the MB1801 mezzanine board and MB2029 MCU RF board, embedding the high-performance, low-power STM32WL33CCV6 sub-GHz application processor. The STMicroelectronics STM32WL3x boards support operation in the 433MHz, 868MHz, and 915MHz frequency bands. The boards feature Arduino® Uno V3 connectivity and ST morpho headers, enabling seamless expansion with a wide range of specialized shields for the STM32 Nucleo open development platform.
Two product variants are available, each featuring dedicated front ends optimized for specific frequency bands.
• The MB2029 MCU RF board for the NUCLEO-WL33xxx boards, featuring the STM32WL33CCV6 sub-GHz application processor (metering line; NUCLEOWL33CC1 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 NUCLEO-WL33xxx and NUCLEO-WL3Rxxx Nucleo-64 Development Boards are supplied with a dedicated software package, HAL library, and various packaged software examples available with the STM32CubeWL3 MCU Package.
