cuplTag is a battery-operated NFC tag that records ambient temperature and humidity. Tap it with your NFC-enabled phone and you'll see the timestamped reading appear in the web app. No configuration required, no application installation required, just one step!
Chhavi is a tiny, wireless, touch capacitive fingerprint sensor with high-end security features, support for ultra-low power operation and optional NFC connectivity. Its open source firmware is fully compatible with the Arduino IDE. Chhavi is powered by ESP32 and features an FPC BM-Lite fingerprint sensor by Fingerprints, giving you and your projects access to the excellent biometric hardware found in many smartphones. Unlike optical fingerprint sensors that are large and power-hungry, this capacitive biometric sensor is small, accurate, and energy-efficient. During our design process, we determined that NFC communication would be a powerful feature for many of the same applications that might require a high-quality fingerprint sensor, but we could not find a major ESP32-driven NFC controller. So we built one into Chhavi as an optional feature. We've also added an optional battery to simplify installation and facilitate mobile deployment. The result is a tiny device with a cutting-edge fingerprint reader, Wi-Fi and Bluetooth capabilities, as well as support for NFC and battery power when needed.

CaribouLite is an affordable open source dual-channel software-defined radio (SDR) platform and an SDR-focused FPGA development framework implemented as a Raspberry Pi (RPi) HAT. CaribouLite turns your Raspberry Pi single-board computer (SBC) into a standalone dual-channel radio Tx/Rx with a tunable spectrum up to 6 GHz. CaribouLite gives you complete control over its hardware, including FPGA, firmware, and all supporting software. With the deeply integrated IceStorm toolchain, writing your own FPGA applications couldn't be easier. You can reuse many Verilog modules, such as the SPI and SMI modules, to support custom applications for CaribouLite hardware.
CANFDuino supports CANFD, the latest version of the CAN bus standard, which can accommodate speeds up to 5 Mbps. It has two local ports with DB9 connectors in a housing that can be mounted on your vehicle or installed in your own projects. The platform is designed for tinkerers, hackers, and industry professionals looking for a ready-made, open source CAN bus solution that requires little or no hardware assembly.
HiPo is a 3.52-inch e-paper display module the size of a business card. Content is uploaded via NFC via a convenient app, no batteries required. The development board can compile different display functions by editing the code.
Aeroh One is a hackable infrared remote control pad that turns any remote control device into a connected device. It will support Alexa, Google Assistant, Apple Siri, iOS/Android App and IFTTT integration. The Aeroh One is compatible with most remote controls that operate via infrared.
AquaPing is an ultra-low power smart sensor that provides isolated water leak detection, even behind walls.
BeanCounter is a pocket-friendly SMT parts counter. Powered by a CR2032 coin cell battery, it uses two infrared photointerrupters to count parts as quickly as possible. It works with any opaque, 8 mm wide carrier tape up to 2 mm, and it covers most 0805 or smaller LEDs and passives, as well as SOT23 transistors.
Plant Bot is an open source project based on ESP32 that allows a single PCB to perform the functions of detecting humidity, watering, providing lighting, and controlling and communicating with the user via WiFi/BLE.
Have you ever wanted to install a security camera in your home, garden or office? Although commercial Wi-Fi security cameras on the market are not expensive, if you want to install multiple ones in different scenes or rooms, it will cost a lot of money. Young engineer Max can develop a wireless security camera based on Espressif's ESP32 chip with only $15.
Have you ever thought about attaching an inertial measurement unit (IMU) to an object to track its posture and motion? Tracer provides high-performance, safe, reliable and low-cost object tracking. Tracer can be easily attached to objects using Velcro. It can tilt and track rhythm as the bike's frame tilts, it can record the number of shots taken with a tennis racquet, and it can even differentiate between topspin and chip shots. Let your imagination run wild and explore more interesting applications of Tracer!
USB-Cereal is a powerful, fully open source development tool that simplifies testing, development, debugging and manufacturing of devices using USB-C. Using the extended capabilities of USB-C, this unique hardware saves time and effort by simplifying debugging and factory log capture, as well as firmware update procedures.
The basic concept of this work is slightly different from standard tools such as a reflow oven or soldering iron. Heat is provided from the bottom of the PCB.
This is what smart home enthusiasts want to control their entire lights, thermostat, or any other smart device from their couch without having to activate a wall switch.
Picoclick is a simple IoT button in a very small package. The size of the PCB is only 18x20mm, and the height with the 300909 battery is only about 10mm. It's able to connect to your local WiFi at an impressive speed of about 1.5 seconds on average. Yes, since it calls IOT-Button, it uses WiFi of course! This opens up countless possibilities for that little device.
Picoclick-C3 The name relates to its new processor, the ESP32-C3, a single-core RISC-V 160MHz CPU. Picoclick C3T is a small WiFi and BLE IoT button suitable for a variety of applications. Originally designed for smart homes, Picoclick can also be used as an actuator for IFTTT automation or as an MQTT device. It is based on the single-core ESP32-C3 RISC-V processor, so it has a lot of useful features. The C3T measures just 10.5mm x 18mm.
The WiFi remote control is based on ESP32 Pico D4 MCU and 160x80 pixel mini TFT display. Additionally, there are onboard I2C temperature and humidity sensors and an accelerometer.
Reflow-Controller is designed to control different types of reflow ovens, hot plates, etc. It's based on the ESP32-S2, so it can be programmed to work with WiFi applications, but it also has an onboard OLED display and three buttons for use as a standalone solution.
