LaskaKit ESPink-4.26 ESP32-S3 e-Paper

Product detailed description

Our completely finished and equipped development boards with ESP32 and glued ePaper display became popular not only among bastlers. We are now expanding our product range with another finished Laskakit ESPink development kit with a 4.26" variant.
It complements the existing family of ready-made ePaper kits such as Laskakit ESPink-Shelf-2.9 ESP32 e-Paper , LaskaKit ESPink-4.2 ESP32 e-Paper and LaskaKit ESPink-Shelf-2.13 ESP32 e-Paper .
If you prefer a separate board, then we have a range of the very economical and versatile ESPink. The board is smaller and more versatile for connecting other ePaper displays.

ESPink-4.26 with ESP32-S3 offers very low power consumption, reasonably large ePaper with large 800x480px resolution, easy programming thanks to the built-in programmer connected to USB-C from which the battery is also charged, connector with unused pins from ESP32-S3 thanks to which additional signals can be brought to the board and last but not least a microSD slot for memory card.

ESPink-4.26 is equipped with two of our universal I2C usup connectors to which you can connect various sensors - SHT40 (temperature, humidity), BME280 (pressure, temperature, humidity), SCD41 (CO2, temperature, humidity), BH1750 (lighting), APDS-9960 (gesture sensor) and many other sensors. Our I2C upstream connector is compatible with Adafruit Stemma and Qwiik from Sparkfun.
In addition to the I2C uplink connector, we also have an SPI uplink connector.
The board supports the popular Live Image project which greatly simplifies the use of the ePaper display to display photos, (google, outlook, apple) calendar, odds, weather station readings, weather forecasts and much more. No need to write code, just upload the correct type of ePaper and board through the web environment and follow the procedure described in documentation.
You can upload the program via the web environment on this page and simply select the board LaskaKit ESPink 3.x and the ePaper type GDEQ0426T82 .

If you want to write your own program, go ahead :-)
On our github you have board schematic and we haven't forgotten sample codesthat should make programming and working with our ESPink-4.26 much easier.

Some technical information:

• ESPink-4.26 has a switch that completely disconnects the board and ePaper from the power supply. Both the battery and the USB.
• IO pins for I2C bus are used - SDA IO42 and SCL IO2.
• The board can be equipped with SHT40, which is connected to the same I2C bus as the external sensors.
• Power supply for external I2C sensors (up), SPI sensors (up), mounted SHT40 sensor, Fuel Gauge MAX17048 and ePaper is switched via GPIO pin 47. Active in HIGH.
• The battery status is monitored by the Fuel Gauge sensor MAX17048 connected to the same I2C bus.
• In addition to the RESET button, there are three other buttons on the board labeled UP (GPIO39), PUSH (GPIO40) and DOWN (GPIO41) - all active in LOW.
• IO pins for SPI bus are used - CS IO46, MOSI IO37, CLK IO14 and MISO IO21.
