LaskaKit ESPink-Shelf-2.13 ESP32 e-Paper
Code: LA100136Product detailed description
A small, design-led development board that has been designed primarily for lowest power consumption and convenient programming.This is the ESPink Shelf 213, a 2.13" ePaper board
And how did we achieve such low, 12.5 uA, power consumption? ESP32 is a powerful chip that allows to connect to Wi-Fi and Bluetooth, but in addition it is very energy efficient, about 5 uA, even in deep-sleep mode.
the ePaper consumes power especially when rewriting the data on the display, but every uA counts so we added a MOSFET on the power supply to de-energize the ePaper when it is not updated.
But we don't stop there - there is also oSup connector, this is a 4 pin connector to which we have a wealth of accessories and has a standard size and pinout. 3.3V power supply, GND and I2C bus. Accessories include cables of various lengths terminated with a wall connector, cables terminated with dupont sleeves or cables terminated with hooks for fast and reliable testing.
The I2C connector power supply can also be de-energized just like the ePaper - the MOSFET switches are GPIO2 control.
