WiCAN is a powerful CAN adapter based on ESP32-C3 that can be used for car hacking and general CAN bus development. It is available in two form factors: OBD-II and standard USB-CAN. The original firmware can interact directly with RealDash using Wi-Fi or BLE, which allows you to create custom dashboards with beautiful graphics. It is available for Android, iOS, and Windows 10. WiCAN connects to your existing Wi-Fi network and any device on that network, and it allows you to configure Wi-Fi and CAN settings through a built-in web interface. Both versions have a power saving mode that detects when the voltage drops below 13 V or other preset values. When this power saving mode is enabled, WiCAN is able to enter sleep mode, reducing the current consumption to less than 1 mA.
AP6xxx series Pin to Pin hardware compatible WiFi modules, mainly with LGA44/12*12mm and LGA-50/15*13mm package sizes. Currently, we are sharing the peripheral circuit reference of the LGA44/12*12mm series WiFi modules.
For the integration of wifi module, the most urgent things in the early stage are
1: the application reference of wifi module peripheral circuit in hardware
2: the driver information in software
You can record your life anytime and anywhere, remember people's names, calculate food calories, translate in real time, and have intelligent conversations...
The circuit board in the project is drawn using Jiali Chuang EDA, and the code uses Arduino IDE, which is very suitable for beginners who are interested in robots.
The software, hardware, and mechanical structure are all open source.
With just a Raspberry Pi Pico, an analog switch and an op amp, you can build a powerful SDR receiver covering the LW, MW and SW bands. Capable of receiving signals from halfway around the world.
The nRF52840 MDK USB Dongle is a small, low-cost development platform implemented by the nRF52840 multi-protocol SoC in a convenient USB Dongle form factor.
Introduction: This socket uses the new national standard five-hole shell, which is easier to wire than the old shell. While retaining the old features (magnetic latching relay, energy metering, OTA upgrade firmware), it also solves the last shortcomings (unstable current counting, shell cannot fit perfectly, etc.). It is a complete metering socket.
The ESPboy CC1101 chip module allows you to detect Sub1Ghz signals (300-348MHz, 387-464MHz, 779-928MHz). Scan, decode, store to open garage doors, obstacles, IoT sensors...
Use ESP32S3 to develop a general module with speech recognition and visual recognition functions. It is mainly used for education, science and technology competitions, and creative design of DIY enthusiasts. The interface and functions are compatible with OpenMV, and its IDE can be used as development and debugging software. Most of the overall hardware design is compatible with ESP32S-EYE, so with a little adjustment of the interface definition, it can be compatible with ESP-WHO. ESP-WHO provides examples such as face detection, face recognition, cat face detection and gesture recognition, thus making this software The module is very playable.
This design is an intelligent desktop interactive robot. As the name suggests, it is an intelligent robot that can interact with people. A 2.4-inch LCD screen is used as an important channel for human-computer information interaction. It also has voice recognition and sound playback functions, making contactless interaction more convenient. The interface design adopts the open source LVGL 8 GUI framework and uses ESP32S3 as the main control chip. The current regional temperature can be displayed on the interface, and the sound can be broadcast through voice interaction. It also displays the dynamics of the EEWORLD forum, including the display of the daily number of posts and the total number of posts. Through voice interaction, the voice broadcast of the total number of posts can also be obtained. . And the onboard LED lights can be controlled by voice.
In the epidemic environment, people don't want to touch things outside, so we create a face recognition access control system that does not require contact. When it is detected that a person is approaching the door, the face recognition device is awakened to save power consumption. When the face recognition passes, the door is controlled to open.
