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.

If you are looking for a simple way to learn soldering, or just want to make a small gadget that you can carry, this set is a great opportunity. Stop me game is an educational kit which teaches you how to solder, and in the end, you get to have your own small game. The LEDs go up and down, and your goal is to press the button as soon as the green LED turns on. With every correct answer, the game gets a bit harder – the time you have to press the button shortens. How many correct answers can you get?

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.
The INA219 is a digital device that allows the measurement of current, voltage, and therefore power. Simply, connect wire serial through this device and it will give all the information provided via I2C communication. It is very simple and reliable to use. It has a jumper for making changes to the I2C address so you can connect more than one INA219 to single microcontroller.
The maximum current of the measurement is determined by the shunt resistor found on the plate which is 0.1ohm (± 3.2A). Yes, it can measure the power in both directions! If you want to measure other currents or smaller currents more precisely, check out the datasheet to change that resistor. The maximum voltage that can be measured is 26V.
The APDS-9960 is a small sensor that measures four things at once. It recognizes the movements you make in front of it (up, down, left, right) and it can identify the proximity of the object, so you have two more movements: to the sensor and from the sensor. In addition, it has an ambient light sensor and a color sensor which gives red, green, and blue (RGB) colors as output. This sensor with many features was even built into the Samsung Galaxy S5 smartphone.
All gestures are detected at a distance of 10 to 20 cm and it has built-in UV and IR filters to make sure it won’t be confused by other sources of light. Connected using well-known I2C communication.
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.

Lithium batteries are charged differently than regular batteries and devices. You’ll need a li-ion charger like this one to charge them. Integrated with the CC/CV charging technology, it is the simplest way to charge a lithium-ion battery.
The board has a USB Type-C connector for power, a JST-type connector for batteries, the charging circuit, a protector, and two status LEDs. Comes with 7 pins that need to be soldered.
Product usage tips:
The red LED glowing means the battery is charging. The green LED glowing means it finished charging. Easy embedding into a project with the four mounting holes on the board.
Note: This charger has protection against short-circuit, too high, or too low voltage. It has no protection against reverse polarity.

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.
