The NeoTrellis M4 is an all-in-one USB + NeoPixel + Elastomer + Audio board. This chip has a speedy core with CircuitPython and Arduino support, hardware DSP/floating point, dual DACs and all the things you expect from normal chips like I2C, ADC, DMA, etc. It has a memory 512KB of flash and 192KB of SRAM so it's great for CircuitPython, added a full 8MB flash chip so tons of space for files and audio clips. Or you can load Arduino in for bonkers-fast audio processing/generation with fork of the PJRC Audio library.
