I use a (TI) DRV8833 - family member of DRV8847 - on a breakout board in combination with the Espruino MDBT42Q breakout board. - 'New' (Pixl.js), in deed, because I came across the (TI) DRV chips on a different path.
Combining something like the super tiny nRF52832 - but in ...40 capacity would be cool, as used in the recently pub'd Espruino-Ring example by @gmurphy - see Espruino Ring, ...and making it a (size-) successor of the Espruino Pico : Espruino Nano-C,.. -C for communicative / communicating / chatting /... ;-)
