paperd.ink is a 4.2" e-paper display coupled with an ESP32 microcontroller. It's open-source,
fully hackable and all the PCB and 3D printing files are available on our Github repo. It’s low
power so you can run it for a month on a single charge. Update wirelessly using WiFi, Bluetooth. Display your calendar, to-do list, weather, custom images, whatever you want. Code using
micropython, Arduino, or ESP-IDF.
It was too hard to launch a hardware product on a shoestring budget dealing with way too many issues amidst the pandemic. But thanks to the HN community, we got a great response last year on our prototype which gave us confidence to move forward!
- tucosan 5y agoWhy is there an image of a satellite dish, when the device provides WiFi/Bluetooth connectivity?
- robertlangdon 5y agoWelp, just an illustration. Sorry for the confusion
- Rebelgecko 5y agoLooks awesome! For the <20uA deep sleep power consumption, is that out of the box when calling the ESP32's deep sleep? Or does it require any extra work like desoldering power LEDs and USB chipsets?
- robertlangdon 5y agoOh no need to desolder, just disable some MOSFETs usings GPIOs in the code. The MOSFETs enable/disable parts of the circuit like SD card, e-paper, battery monitoring, etc
