Inkplate 2 wireless ePaper display is by far the smallest display from Soldered Electronics with a 2.13-inch 3-color ePaper display while previous Inkplate models rely on 6-inch to 9.7-inch ePaper displays.
The tiny display board integrates an ESP32 dual-core wireless microcontroller that drives the display, provides WiFi and Bluetooth connectivity plus some I/Os, and can be programmed with the Arduino IDE or MicroPython.
Inkplate 2 specifications:
- Wireless module – ESP32-WROVER-E module with ESP32 dual-core microcontroller with Wi-Fi 4 & Bluetooth 4.0 connectivity, 8MB PSRAM, 4MB flash (Note: The product’s description lists 8MB flash, and 4MB RAM, but there’s no ESP32-WROVER-E in this configuration)
- Antenna- External IPX antenna
- Display – 2.13-inch ePaper display with
- 212×104 resolution (111 DPI)
- Red, black, and white colors
- 15 seconds full refresh time (no partial update)
- USB – 1x USB Type-C port for power and programming via CH340 USB to TLL chip
- 20-pin header with GPIOs, I2C, UART, 3.3V and GND
- easyC I2C connector compatible with the Qwiic connector
- Power Supply
- 5V via USB Type-C port
- Solder pads for Li-ion battery, MCP73831 charger IC
- Power Consumption – 8uA
- Dimensions – 65.2 x 35.3 mm
The InkPlate 2 is mostly designed to be programmed in the Arduino IDE using the Inkplate library itself based on the Adafruit GFX library, and with several code samples albeit none of which are specifically designed for the 2.13-inch wireless display at this time. There are two other ways to control the display either with MicroPython or using the board as a peripheral receiving UART commands from a host microcontroller to update the display. All displays will ship with the “peripheral mode” firmware. Finally, Soldered Electronics also provides a web-based GUI editor, which has yet to be updated to support the Inkplate 2. The full documentation for all Inkplate displays can be accessed on the Readthedocs website.
e-Radionica and Soldered Electronics used to introduce their displays on Crowd Supply, but the Inkplate 2 was launched on Kickstarter instead. The project has already surpassed its $10,000 funding target with close to $30,000 raised so far. Rewards start at $35 for the Inkplate 2 board, but you could also pledge $55 for a kit that adds an enclosure and a battery. Expected shipping costs are $12 within the European Union, $15 for the USA, and $19 for the rest of the world. Deliveries are scheduled to start in March 2023.
