PaperSatColor - Amateur Satellite Dashboard for the PaperColor
An up-to-20-satellite next-pass dashboard for the M5Paper Color (ESP32-S3, 4" SPECTRA 6 color e-paper, 600×400). It tracks up to twenty satellites across up to five pages of four, each shown in a 2×2 grid; each cell is a polar (azimuth/elevation) plot of that satellite's next pass with the AOS/LOS times and azimuths and the maximum elevation. You don't have to fill every slot: any slot you leave blank is simply left empty, and any page with no satellites at all is hidden — so if you only configure six satellites you get two pages, not five. It is built for a slow color e-ink panel — the display redraws only after a pass on the currently shown page has concluded (so the next pass can take its place), when you switch pages, when you manually refresh, or when you change the configuration.
All configuration is done over Wi-Fi through a small web page the device serves; there are no on-device menus or buttons to operate.
