It comes in two variants, with either an STM32H750VB (128 kiB Flash) or STM32H743VI (1 MiB Flash).
In addition, there is also a 8 MiB QSPI flash as well as an SD card reader.
The CPU is programmable using the standard ST USB DFU bootloader or via the SWD interface.
I don’t know how similar this Cortex-M7 part is to the already supported STM32F7, but it might be the only one missing from the STM32 family that we don’t support yet.
The Pine Pinenut (BL602) is available for free, for a certain amount of time. Keep in mind that they only have 1000 and they would like to see some porting effort for them.
Wow, I’ve been looking at some of these boards for a while! Especially The SparkFun Edge. A couple IoT cores: Ibex and [CV32E40P] were made by

Another company that’s new to me, also there is no way to publicly buy those chips or the SDK, so not sure how useful that is. You can request samples though.
Oh yes, you are right!
The shielding looked different, so I thought they must be new (and they came up when searching for ESP32-C3, thanks fuzzy search…)
I was gathering info about multi Core MCUs and discovered that Rockchip, better known for their multimedia application processors, also has a line of MCUs.
Those seem to be focused on audio processing, RKNanoC is a single Cortex M3, but there is also the Dual Core RKNanoD:
2x Cortex M3 (one core at 250 MHz, the other at 500 MHz)
