Handcrafted and uniqueAll this epapers housings are designed by us, they are built by hand with care, and attention to detail. They are tested and shipped with printed documentation explaining how is the wiring made in case you want to flash a different firmware to the esp32 controller. They also come with a battery that can work for about a month without being recharged. They can be recharged just leaving it connected a full night with a mini-USB to work for another long period. All of them have either a on/off switch or a reset button. They can also be shipped with your desired WiFi access point and password, pointing to your Screen in CALE.es web-service, provided you have an account with us.
How to make a purchase
Just register and contact us using the User Get Support
option and let us know what epaper you want to purchase.
We will reserve it for you. The sale is closed when we receive the payment in any of the offered channels (Ethereum transfer, paypal, wire-transfer)
Customized for you
Before sending it to you we will customize the Firmware, with your WiFi access point and Screen, and also the update frequency (ex. Every hour).
When the package arrives you can switch it on and see your Screen rendered. Without complications and pre-configured. But if you want to hack your epaper and flash it with customized firmware, we will also send you an A4 printed page, with the wiring details between the ESP32 and the eink display. That way you can use any of our Firmware flavours, CALE-IDF or the Arduino-esp32 version, and make all the custom modifications that you wish.
