So how many RPIs are hiding in your closets? I think I've got 3x RPI1B, 2x RPI2B, 2x RPI3B, 2x RPI3B+. Amazing little machines! I do wish RPI4 gets USB-C por

So how many RPIs are hiding in your closets?
I think I've got 3x RPI1B, 2x RPI2B, 2x RPI3B, 2x RPI3B+.
Amazing little machines!
I do wish RPI4 gets USB-C ports. Well, USB3 would do.
I'd also love to have another board with very low power requirements, even less than RPI zeros. Something between Arduino/ESP8266/ESP32/etc. and RPI zero, but can still run Linux.
Like ARM Cortex M7 or similar. Mash one or two ultra low power M0/M1 (so that main core can be completely switched off for low power while remaining active), advanced DMA/DSP engine (like IMX SDMA (NXP?) or TI PRU), lots of reconfigurable IO (fast GPIO, I2C, I2S, (wide) SPI@80MHz+, ADCs, USB 2.0 device/host, bluetooth, wifi, 100M ethernet MAC etc.).
Oh and some digital display interface would be nice as well, it's not nice to connect displays to SPI or worse, I2C.
1 MB SRAM and maybe 16 kB low power SRAM, shared with M0. 16-128 MB low power DRAM.
You should be able to fine grain power off any and all of the components, even DRAM and SRAM (except for that 16 kB shared between M0 and M7).
Oh, and can I get it tomorrow? ;)
