STEVAL-FSM01M1: ST's dual-channel digital I/O module for industrial safety applications

Schematic PCB

USB-C "switch", hardware open source, firmware provided

The basic functions of USB-C are supported, such as high-speed communication and charging functions. Then this design solves the problem of painless switching between one host and multiple devices, or one device and multiple hosts.

Schematic PCB

Open source USB2.0 high-speed analyzer

The analyzer host computer directly uses Wireshark. The hardware is implemented using Cypress CY7C68013A MCU + Lattice LCMXO2 FPGA + Microchip USB3343 USB PHY

Schematic PCB

kicad USB splitter: a three-way USB splitter for personal design and use

A simple USB switch so I can swap a keyboard or mouse between two computers.

It is operated by 4 single mechanical switches, 1 for each channel. Simple designs can be implemented.

Schematic PCB

110/220VAC optically isolated zero-crossing detector module for DIN rail bracket mounting with 3.3V or 5V output - ideal for Arduino, ESP32/ESP8266

Detects Zero Cross point of AC supply (110/220VAC) and outputs a 1ms square pulse at 3.3V or 5V. 72mm x 20mm for DIN rail carrier mount.

Smart Gate Drive Coupler Evaluation Board

This reference design provides design guidelines, data, and more for the smart gate drive coupler evaluation board.

Schematic PCB

Low-cost 2.5KV USB power isolation solution (schematic + BOM + gerber, etc.)

This is a low-cost isolation achieved through a power transformer. Since the transformer is more convenient for AC isolation, but DC is not suitable, ATtiny412 is specially used for control.

MC68HC908JW32 Evaluation Kit Hardware/Software Example

The KITUSBSPIEVME evaluation kit is an available hardware/software example that allows users to become familiar with the MC68HC908JW32 through practical applications, USB to SPI and USB to parallel converters. The main function of this demo board is to support a PC without a parallel port, which can communicate with other NXP evaluation boards through the USB port. USB ports are a standard feature on almost every new PC. The kit utilizes the MC68HC908JW32's built-in USB, SPI and parallel ports.
