with board support and functionality all tested, its time to neaten up the board and get ready for pcb ordering. top silk is done here, bottom silk still needs some work.
we've got the pretty-pins diagram made to verify pin functionality. in order to get the high speed spi port exposed, we dropped the adc's on those pins - you still get adc on all the other breakout pads.
schematic is minimal but, hey, it seems to work! since this qt py would be most benefited by a battery input, we popped another schottky on the bottom and a vbat pad. this is also our first 4 layer board.
we could probably design it without inner ground/3.3V but given we aren't using a module, and there's an antenna on there, it would probably benefit to have an extra big plane. the pcb is small enough the cost won't be much higher.
and, of course - we still have plenty of ππΈπͺΆ rp2040's when you ποΈπ²9οΈβ£9οΈβ£ or more - plus big discounts on everything in adafruit.com/feather

CircuitPython works with QT Py ESP32-S2 board :) Plus, get a free Pink RP2040 Feather in our Feather Friday sale!
This ESP32-S2 QT Py is so smol i just wannna pinch its lil cheeks! on the back is and ESP32-S2 with 4 MB Flash and 2MB PSRAM all stuffed inside this QFN chip.
we verified Arduino works last night. So today we've been testing out CircuitPython support. Here's an Adafruit IO demo that sends sensor data from plug-n-play QT boards over MQTT to a dashboard. this demo has been runnin all day flawlessly.
Just a few more tweaks to the design and silkscreen before we send off the PCBs - what color should we make this board? :)
oh and...don't forget, we've got 20% everything in the feather category at adafruit.com/feather
