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.
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.
This reference design is a 2cm x 2cm RGB LED animation solution for battery powered applications using the LP5523 and MSP430FR2111 devices. The LP5523 device is an LED driver with a programmable control engine in a DSBGA package. The LP5523 provides realistic lighting patterns for applications that must fit on extremely small PCBs. The design demonstrates full functionality while using limited MCU resources.
This board is a Swiss Army Knife for IoT security researchers, developers, and enthusiasts. The board can be used with different types of software, including third-party sniffers such as SmartRF Packet Sniffer, Sniffle, zigbee2mqtt, Z-Stack-firmware, Ubiqua Protocol Analyzer, our custom firmware, or you can even Specific software requires writing your own software.
RSL10 QFN EVB is used as the main control of IOT lamps. Because the GPIO of RSL10 is limited, the data protocol adopts single-line return-to-zero code communication method. The system only needs one GPIO1 as the LED RGBW driver. GPIO is used to drive WS2812. WS2812 is a control circuit and An intelligent externally controlled LED light source with integrated light-emitting circuit. Its appearance is the same as a 5050LED lamp bead, and each component is a pixel. The pixel contains an intelligent digital interface data latch signal shaping amplification drive circuit, a high-precision internal oscillator and a 12V high-voltage programmable constant current control section, which effectively ensures that the color of the pixel light is highly consistent. , the other ADC port is used to collect the temperature of the lamp, and when the temperature exceeds the limit standard, it automatically reduces the luminous efficiency of the lamp to avoid burning out the LED due to excessive temperature.
Alex Newton released an IoT electrocardiogram monitoring (ECG) tutorial based on ESP32, demonstrating that remote cardiac monitoring can be carried out no matter how far the distance is between the doctor and the patient.
The ST25-TAG-BAG-UB is a ready-to-use tag set, containing tags based on NFC Forum Type 5 tag ICs (ST25TV02K and ST25TV02KC) or on NFC Forum Type 4 tag ICs (ST25TA02KB and ST25TA64K).
