things i'd like to see in future iterations - hopefully ordered by BOM cost (have zero experience with hardware design):
- RTC (for the battery replacement argument - I'd be fine using an AA/AAA battery if that's a thing - it is a thing for a couple of my kitchen clocks, though)
- female GPIO
- headphone/mic jacks or combo jack
- full-size HDMI port
- 8 GB RAM
- NVME storage option
- battery
- display
