alt Hacker News"Since the ESP32 only supports 8MB of onboard storage" - an SD card breakout with SPI interface costs 2 bucks. That would be an easy addition. I think there are also ESP32 boards with SD card slot but this would also make for a nice PCB.

Wait, are they suggesting using the Heltec Lora ESP32 board? That is a super odd choice. Adafruit has the boards you speak of and they have tri-color too and more features in the same form factor. Why buy a Heltec Lora board to use as an e-reader and waste money on a perfectly good Lora chip on it...
