LaskaKit microESPink ESP32-S3 e-Paper

Product detailed description

The MicroESPink thus complements the separate board we also offer, the very economical and versatile ESPink. MicroESPink is smaller and can also connect other ePaper displays.

MicroESPink is based on ESP32-S3 instead of ESP32 (larger ESPink). We saved space by removing unused GPIO pins on the edge of the ESPink board, SPI usup connector etc.

If you prefer a ready-made kit with attached ePaper, then we offer Laskakit ESPink-Shelf-2.9 ESP32 e-Paper, LaskaKit ESPink-4.2 ESP32 e-Paper and LaskaKit ESPink-Shelf-2.13 ESP32 e-Paper.

MicroESPink is based on the ESP32-S3 chip, which has support for both Wi-Fi 4 and Bluetooth 5. The board contains a connector for the JST-SH battery with a pitch of 1mm. You can find the cable for this connector in our e-shop, the ready-made batteries with this connector are 200mAh and 400mAh.

The charging current is set by resistor R11.

MicroESPink is equipped with our universal I2C port connector 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.

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. There is no need to write code, just upload the correct ePaper and board type through the web environment and follow the procedure described in the documentation.
You can upload the program via the web environment on this page and simply select the board LaskaKit ESPink 3.x and the correct type of ePaper depending on the one you ordered.

If you want to write your own program, go ahead :-)
On our github you can find a schematic of the board and we haven't forgotten the sample codes, which should make programming and working with our microESPink much easier.

Some technical information:

• The board consumption is around 16uA without connected peripherals.
• IO pins for I2C bus are used - SDA IO42 and SCL IO2.
• Power supply for external I2C sensors (uŠup), 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. Its ALERT output is connected to GPIO pin 9.
• MicroESPink has two soldering bridges which are used to adjust the driver settings on the board - see the diagram for a description of the settings for ePapers.
• Both the battery is charged via USB-C and the board is programmed.
• The board must be switched to recording mode, this is done by the following procedure: connect USB-C, press and hold the FLASH button, press and release the RESET button and then release the FLASH button.
