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.
This dice mainly consists of an ESP8285-01F, six PCBs and 54 LEDs. Its structural design is very clever, and the exquisiteness of the structure is also reflected in the production process.
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.
Amethyst is a classic home computer developed by Matt Sarnoff. It has an integrated keyboard, can generate sounds and images, uses the Forth programming language, has image and voice commands, a debugger and screen editing functions.
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).
Lithium-ion battery monitoring and gas meter evaluation board based on STC3100
ST25R3916 based NFC reader expansion board for STM32 and STM8 Nucleo
The lazy self-care fish tank control system is mainly aimed at fish farming enthusiasts. As long as you use your mobile phone through BLE, you can manually control the start, stop, and feeding of the fish tank's electrical appliances. At the same time, the real-time time, supplementary lighting time, automatic feeding time, water temperature monitoring and alarm, etc. can be set through the APP at once. Enthusiasts are only responsible for watching and appreciating the fish, and the other things are left to the control system!
