What is the WiPy 2.0 and LoPy CPU Clock Rate ?

[VitalSparkPlug]

I am completing a MicroPython board spec comparison...
started with Free RAM and internal ROM...
but I've expanded it now :-()

The Spec sheets for WiPy 2.0 and LoPy are very nice and complete...except for MCU Clock rate (MHz).
WiPy 1.0 has...
Processing
★Dual processor + WiFi radio SoC.
★MCU: Texas Instrument CC3200, Cortex-M4 @ 80MHz
WiPy 2.0 and LoPy just have...
Processing
– Espressif ESP32 chipset
– Dual processor and WiFi radio system on chip

What are the MCU Clock rates for the WiPy 2.0 and LoPy ?

@VitalSparkPlug, the max frequency is 240 MHz. Right now we're clocking it at 160MHz. Hope it helps ;)

Thanks for the speedy reply.
Might need to update the Spec Sheet (Frequency is a "Basic" spec :-) )
Is that for Both WiPy 2.0 and LoPy ?
Can the Max you mentioned be reached by firmware control of the PLL?

@VitalSparkPlug, yes, both boards are ticking at 160MHz right now. Right now changing the clock requires a firmware rebuild, but this limitation might be lifted in the future.

Being more specific, MicroPython release 0.9.6.b1 for LoPy and WiPy 2 has default ESP32 frequency set as 160 MHz, instead of 80 MHz as before.
