The Inkplate 2 is an Arduino-compatible board that features a 2.13″ three-color e-paper display. It is a plug-and-play device, programmable via USB port, and controlled by an ESP32 microcontroller. Moreover, it connects to the internet via WiFi or Bluetooth. Since it uses only 8uA in low-power mode, it can last for months on a single Li-ion battery charge. It’s simple enough to be used by beginners, but it also offers plenty of features and a user-friendly platform for advanced users. Inkplate 2 has it all, packed on a small-factor board.

If you’re like us, when you first saw an e-book reader, you thought “If only I could use a screen like this in my project”. Thanks to the exceptional sharpness and contrast, the ability to display in sunlight and truly unprecedented efficiency in terms of energy (it consumes energy only when changing the content on the screen), electronic paper is the ideal choice for many applications. Inkplate 2, continuing the tradition of the now well-known Inkplate series, offers a variation of e-paper accessible to hobbyists and everyone else in a way that we have created a plug-and-play hardware that is really easy to use, and is compatible with Arduino and micropython.

Inkplate 2 options:

With e-paper display & enclosure: This version offers a sturdy and sleek enclosure for your device, made with precision from a 3D printer. It’s perfect for those who want an extra layer of protection without any added features.

With e-paper display, enclosure, and battery: Upgrade to this version if you’re looking for both protection and mobility. This option includes a 3D-printed enclosure as well as an integrated battery, ensuring your device stays powered even on the go.

Without e-paper display: For those who prefer a simpler or alternative display solution, this version does not include the e-paper display. It’s ideal for users who have their own display solutions or prefer to use the device without a visual interface.

How many times have you watered your plants and feared you’re overdoing it? With the simple soil humidity sensor, those worries are a thing of the past! This two-part sensor is straightforward to use. The two exposed prongs go into the soil and send the humidity information to the sensor via the connected wire. The more water is in the ground, the better the results will be.

The two pieces are connected with the provided JST-SH 2-pin cable. The sensor uses the LM393 differential comparator. The main benefit of this board is ability to give analog and digital output. By setting the potentiometer on the board, you are able to get digital signal at the DO pin when signal crosses certain value, while analog values will be present on the AO pin at all times.

This logic level converter board module gives us a translation of logic level between two signals. In layman’s terms, if we take a signal with logical “unit” on 5V convert into a signal which logical “unit” has on 3.3V this module will help us. Something like this is useful in this case if we want to achieve communication between two devices from whom one works on 5V and the other on 3.3V, or any other combination of voltages. Directly connecting we would “burn” a device that works on 3.3V and a module gives us to avoid that.

They say that whoever works – makes mistakes. Well so do we! We have an old circuit board that we rest from unsuccessful projects or are simply a bug. There has excess PCBs of prototype products or serial products that are no longer manufactured. You will find everything, not necessarily functional 🙂

Use these chips to practice soldering on them, like a keychain or decoration for the wall. Give them to a friend. Make your next project on them. Let your imagination run wild 🙂

Note: Do not take these printed circuit boards as functional. We can not offer technical support for them. Some of them may have a number of brazed components.
