Do the STM32WB Nucleo boards have the HSE crystals pre-calibrated from STM?

[CMasc.1]

I am a hobbyist that only has basic oscilloscope and function generator that is (according to AN5042) not accurate enough to tune the HSE crystal. Is the HSE crystal in the NUCLEO-WB55RG pre-tuned?

Crystals are “good enough“ for many applications without any tuning. Typical accuracy might be between 10 parts-per-million (ppm) and 50 ppm.

That’s what you’ll get on your Nucleo board.

If you need better accuracy and/or stability for example when making test-equipment or narrowband radio, then you need to compensate for changes in crystal characteristics over temperature with a “Temperature Compensated Crystal Oscillator�? (TCXO). Such oscillators burn more power than the “basic�? crystal oscillators that stm32 are designed for.

Crystals are much better than internal oscillators, which even with calibration struggle to achieve accuracy of 1% (10000 ppm) and even that’s just at one temperature!

Hello,

On the STM32WB Nucleo board, the HSE crystal is already tune.
