1st well done and congratulations on the Teensy 4.0 and 4.1 they look great and for the cost it's got an amazing cost / power price point.

I'm seriously looking at it now to use instead of the above mentioned STM32 I'm using exclusively.

Things I have working in the STM32....

1) Built in 4 bit SD slot
2) RTC onboard
3) 2x 12 bit DAC
4) Ability to have multiple DMA hardware SPI
5) "fast" 168Mhz, 32 bit processor with 192k SRAM and 512K program memory
6) Heaps of pins!!!

I have my STM32 rendering 60fps on a 128*128 SSD1351 with 8192Hz 12 bit sound using micro SD so would assume this newer hardware should breeze through that.

As anyone can see the 4.1 seems to blow most of these values out of the water.

This iteration has seriously raised the bar!
