An open-source USB to CAN adapter: It supports CAN bit-rates of up to 1 Mbit/s. The product comes with an open-source SocketCAN driver software. It features a Micro-USB connector and a 4-pin screw terminal with CAN_H, CAN_L, 5-V supply, and ground. The CANable device is a hardware...

BML project for using a $2 FTDI FT260Q for adding 14 bits of GPIO to any PC via USB with no device drivers required. Ever miss the simple days of using a PC’s LPT1 parallel port to bit-bang GPIO over 8 output pins and 4 input pins of the DB-25 connector? I sure do. My first design...

Regardless of how strong a password is, or what level of code-based authentication a website is using, any system that sends codes in a text message can be hacked by a skilled hacker. The most secure way to set up two-factor authentication is to use a reliable app on a smartphone to...

A 10.8A, 4 port USB charger with a wattmeter and adaptive intelligent charging. It works by taking any DC input between 7V to 17V, from an AC/DC adapter or car adapter. It can be used anywhere with wall outlets, car power ports, lead-acid batteries, DC-output solar panels, and...

This is an Open hardware USB true random number generator coming soon on crowdsupply.com The Infinite Noise TRNG is an affordable and secure true random number generator (TRNG) based on a modular entropy multiplier technique that continuously loops over previous random output,...

Simple, tiny USB to UART converter with digital isolator working between 2.5V and 5V up to 3Mbaud, with the Arduino Pro mini connector. It's a USB to UART converter with a digital isolator at the UART side. It has a micro USB for connecting to the PC and a 6 pin header with the same...

This project provides 12V output from any USB power source, like PC USB port, USB adapter or power banks. LM2577ADJ boost converter IC is the heart of the project. The IC can handle load up to 800mA, it’s advisable to use only 200mA load on output to be on the safe side. The LM2577...
