ID205L port, any hopes?

Yes, it was originally the idea, but there were a few things against it.

• nRF52840, but no USB
  
• relatively expensive
  
• The 240x240 display is SPI and it's really hard to get it to update fast enough that it's not laggy
  
• It's basically impossible to open - out of 5 of them I had I think I managed to get just a single one disassembled that worked ok (by drilling into the back in order to poke the display out the front)
  
  

So basically you need the factory on board, and IDOOSmart said they would flash custom software for 500pcs, but then they turned around late in development and said 1000. When I came to order they said 3000 - and that's when I decided to change suppliers.

But the firmware itself should still work ok I imagine... With some tweaks you might even be able to make it compatible with existing apps.
