YCP-MB1389000STM32WL Nucleo-73 evaluation board (NUCLEO-WL55JC1)

Introduction The NUCLEO-WL55JC STM32WL Nucleo-64 board, based on the MB1389 reference board (NUCLEO-WL55JC1 and NUCLEO-WL55JC2 order codes), provides an affordable and flexible way for users to try out new concepts and build prototypes with the STM32WL Series microcontroller, choosing from the various combinations of performance, power consumption, and features. The ARDUINO ® Uno V3 connectivity support and the ST morpho headers provide an easy means of expanding the functionality of the STM32WL Nucleo open development platform with a wide choice of specialized shields. The STM32WL Nucleo-64 board does not require any separate probe as it integrates the STLINK-V3E debugger and programmer. The STM32WL Nucleo-64 board is provided with the STM32WL comprehensive software HAL library and various packaged software examples available with the STM32CubeWL MCU Package. Figure 1.

R GP ∏ = ²..4 ... R PRIE ∏ S: Power density (mW/cm²) P: Peak output power at antenna terminal (mW) G: Numerical Antenna gain (GidB = 2.0dBi) R: Distance of radiation to antenna (cm) MPE F = 902.5 / 925.0MHz E.I.R.P = 199.5mW (21dBm + 2.0dBi) R= 20cm S=0.04mW/cm² MPE limit for uncontrolled exposure: 0.6mW/cm²  Below MPE limit Note: RF output power is taken as rated power including tune-up tolerances. Conclusion: Therefore the device complies with FCC’s RF radiation exposure limits for general population for a mobile device.
