15 V/200 mA step-down converter based on VIPER122
LPC-Link 2 is an extensible, stand-alone hardware debugger that can be configured to support a variety of development tools and IDEs using a variety of downloadable firmware. Additionally, it serves as an evaluation board in its own right for evaluating NXPLPC4370 triple-core MCU. Combined with the Embedded Artists add-on board, it can be used as an oscilloscope or logic analyzer!

This power module generates all the voltages required to power the Class D audio amplifier. The main output voltage is 36V, which provides 200W of continuous power and 540W of peak power. The first stage is a power factor correction boost. The flyback converter provides 12V on the primary side and 12V (300mA) and 3.3V (200mA) on the secondary side. Using a hardware switch and remote input, the converter can enter standby mode: in this state, the 36V output is disabled and 12V, 3.3V are "always on". In this way, the standby power can be reduced to 150mW (115Vac) and 270mW (230Vac). A second digital input switches the main input voltage from 36V to 18V, allowing it to enter a low-current consumption mode when the audio amplifier requires less power.
This Bilibili small TV uses esp32 as the main control, lvgl GUI interface design, and is developed based on idf4.0 to support smartconfig or WeChat airkiss distribution. Its functions include: network connection display, network acquisition time, weather display, temperature and humidity collection, Fan count display, mqtt temperature and humidity upload, etc. All software and hardware are open source.
This document details the Riverside (MAXREFDES8#) subsystem reference design, a 3.3V input, 12V (15V) output isolated power supply. The Riverside reference design includes a 3W primary-side transformer H-bridge driver for isolated supplies, and one wide input range and adjustable output low dropout (LDO) linear regulator. Test results and hardware files are included.
TI Designs TIDA-00449 is a ready-to-use and tested hardware platform for monitoring, balancing and protecting power tool 10-cell series battery packs. Power tools increasingly use high power density battery packs based on lithium-ion or lithium iron phosphate cells, which require explosion protection against incorrect charging or discharging. TIDA-00449 also meets the thermal requirements for power tool battery packs when discharged at sustained high currents.
The USB Type-C™ Audio Adapter Accessory Mode Reference Design provides a solution for transmitting analog audio over the USB Type-C interface. This reference design demonstrates how to use the USB Type-C standard audio adapter accessory mode to transmit analog audio to system peripherals while still transmitting USB data through the same USB Type-C connector.
Based on ESP32 and ATtiny861 to build a Nintendo NES game emulator handheld console with complete materials for making the project
MCIMX8M-EVK is an evaluation kit for i.MX 8MQuad, which provides high performance with high-speed interface and audio and video functions.
