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.
OM6716 is a transponder evaluation and development tool for HITAG transponders and used with the 434 MHz UHF band RF expansion board for RKE/PKE applications.
QN9080SIP-DK is a development kit supported by the QN9080-001-M17 module, supporting Bluetooth 5 and NFC.
The RSL10 module is plugged into the self-made optocoupler isolation circuit board, and the entire module is connected in series with the modified target instrument (4-20mA two-wire passive digital display meter) and then connected to the 4- In the 20mA current loop, when the actual working zero current is 4mA, the target instrument displays 4.000mA in the current mode; the overall voltage drop of the circuit board of the work is 2.513V; the changed range or unit is sent to the RSL10 on the circuit of the work through the mobile APP Setting command, the target instrument (currently its own voltage drops by more than 1V) will be changed by Bluetooth remote control to change the setting state, such as switching to different ranges or displaying different measured physical quantity units, etc.
easySwitchBox does one simple thing - it sends an on/off signal to any relay, actuator or other item. It can be used to trigger any event wirelessly and over long distances (even up to several kilometers using LoRa®). Programming is easy using the Arduino IDE, and communication is protected by a certified chip. easySwitchBox not only makes your projects more efficient, but also looks more professional.
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.
FossaSat-1 uses cheap LoRa modules to provide free and open source IoT communications around the world, allowing students to communicate with satellites for less than 20 euros.
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...
It consists of two parts: the outdoor end (Outdoor) and the indoor end (Indoor). The Outdoor end can be placed outside the window to monitor real-time outdoor temperature, humidity, air pressure, illumination and other information. The Indoor is placed indoors to receive weather data and display it.
This is an open source work by netizen aziddy, based on the classic Adafruit Feather 328P development board (the MCU master is Microchip's ATmega328P) and a mini electronic game console with a 128x64 OLED screen
The author specially bought a laptop motherboard, and then DIYed the peripherals and casing. The overall effect is quite beautiful.
The project implementation uses RSL10 and external mechanical control structure to complete wireless control of traditional switches.
NXP's OM2385/SF001 development kit for SIGFOX applications, including OL2385 and Kinetis KL43 series MCUs for host applications
A smart wearable device based on the RSL10 development board officially provided by EEWORLD. This device is divided into two parts: the host and the slave. However, this MCU only has one UART, but in actual project requirements we need to use two UARTs. The organizer of this event gave five boards, so a board without a sensor is used as the SPI slave and will receive The command parses and uses AT commands to control the audio.
The Bidirectional 400V-12V DC/DC Converter Reference Design implements an isolated bidirectional DC/DC converter based on a microcontroller. The phase-shifted full bridge (PSFB) with synchronous rectification controls the power flow from the 400V bus/battery to the 12V battery in buck mode, while the push-pull stage controls the reverse power flow from the low-voltage battery to the high-voltage bus/battery in boost mode. . This implementation uses a Texas Instruments (TI) 32-bit microcontroller TMS320F28035 on the low-voltage side to achieve closed-loop control of bidirectional power flow. This digital controller system implements advanced control strategies to optimally control power stages under varying conditions and provides system-level intelligence for safe and seamless transitions between operating and PWM switching modes.
Bluetooth ® Low Energy-NFC-v2.0 is an NFC expansion board for QN9020DK and an extensible QN9020 application development platform. This NFC expansion board is based on CLRC663+, a high-performance multi-protocol NFC front-end.
