Weighted comparison for BitInk — a Wi-Fi/BLE e-paper display that wakes, pushes ~120 KB, and sleeps.
The ESP32-C5 introduces dual-band 2.4/5 GHz Wi-Fi 6 to the ESP32 family. For always-on devices that's compelling. But for a battery-powered e-paper device with intermittent wake cycles and small payloads, the tradeoffs look very different.
