STMicroelectronics STM32WL33 Development Boards
STMicroelectronics STM32WL33 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 STM32WL33 boards support operation in 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. Each board has a dedicated software package, including the HAL library and STM32CubeWL3 MCU Package, with various software examples. Two product variants are available, each featuring dedicated front ends optimized for specific frequency bands.
