This solution has a built-in font library and image gallery, and supports fast printing. It can be connected to a computer or cash register for printing. Integrating functions into a microcontroller saves PCB space and reduces printer size.
The smart player integrates multimedia playback, network interconnection, human-computer interaction and other applications. As a co-processor, Nuvoton microcontroller's main functions are power control, audio and video link switching, human-computer interaction and function module control.
Stereo Mic and Speaker HAT is an audio HAT for the Raspberry Pi board with dual speakers and microphones for stereo audio playback and recording. HAT does not need to be installed as the onboard EEPROM dynamically loads device tree overlays. First, all you need to do is plug in the HAT and boot up the Pi. Make sure not to plug or unplug the HAT while the Pi is powered on and running, but really, it's that simple! By default the amplifier gain is +9dB, but the amplifier gain can be changed via the onboard pads by adding a small amount of solder. The compact HAT measures 65mmx30mm, which is the same size as the Pi Zero, Adafruit's bonnet HAT and Pimoroni's pHAT, making it easy to use the HAT for a variety of projects.
An N329 series microprocessor is used to integrate all functions of the digital video recorder: CMOS camera, hardware image codec, LCD control interface, TV signal encoder, SD card interface, USB Host controller and USB 2.0 Device controller, etc. The N329 series integrates the functions required by digital video recorders, such as: CMOS camera interface, hardware image codec, ADC, DAC, LCD control interface, TV signal encoder, SD card interface, USB Host controller and USB 2.0 Device control recorder, etc., which makes N329 a cost-effective digital video recorder application chip. In addition, N329 also stacks DRAM in the same LQFP package, which allows the PCBA to easily pass EMI and EMC tests.
ANAVI Gas Detector is an open source, easy-to-use, Wi-Fi compatible development board for monitoring air quality and detecting hazardous gases. It supports popular analog MQ gas sensor modules such as MQ-135, MQ-2, MQ-3, etc. In addition, it comes with slots for a mini OLED display and up to three additional I²C sensor modules, including for the precise digital sensor HTU21D to measure temperature and humidity. Air pollution is a very serious problem. Monitoring air quality and detecting toxic gases can improve a person's quality of life. All these features make the ANAVI gas detector suitable for developers, manufacturers, students and open source enthusiasts interested in home automation and environmentally friendly lifestyles.
The GoWired Multi-Protocol Gateway is an evolution of one of our previous development boards, the GetWired Ethernet Gateway, with more power, more features, more functionality and a better solution for wired automation systems. It features a powerful ARM M0+ microcontroller with 8x the ROM and 16x the RAM memory. We doubled the RS485 transceiver to be able to use two different communication protocols simultaneously (MySensors, MODBUS, etc.) and added a CAN transceiver as it is also widely used in home automation. USB obviously has to be included as well. To ensure reliable Ethernet communication, we use the market-leading Wiznet W5500 chip. The microcontroller internal memory can be expanded via SD card, for example. G. Used to collect debugging information. The GoWired multi-protocol gateway also features improved power circuitry and can now handle a voltage range of 7-26 VDC. Onboard current and power monitors can periodically share power-related data, as well as other information about device status. For example, an e-ink screen can be used to display this information. All of this is designed with reliability and safety in mind, especially in terms of power supply (ESD, overcurrent, overvoltage, reverse polarity protection) and EMC and EMI precautions. The device is housed in a compact four-slot DIN rail enclosure.
Inkplate 6PLUS is a powerful, energy-efficient, Wi-Fi-enabled ESP32 development board with a recyclable 6.0-inch e-paper display equipped with touch screen and headlight. It's part of the Inkplate family of open hardware powered by open source software libraries, making it the easiest electronic cardboard to use, whether you prefer the Arduino IDE or MicroPython.
Provides a reference solution that integrates control of Bluetooth signal conversion and transmission, LCD display transmission, power management, and sound quality optimization chip control. Using the high-performance, small-sized Mini51 series, it can be widely used in Bluetooth hands-free speakers, smart phones, and tablet computers.
