WebDec 29, 2024 · I've used a generator that supplied a 5V voltage while measuring the intensity : the arduino Uno itself uses 60mA, connecting it to the computer through serial uses 40mA (for a reason I don't understand), and connecting the keyboard uses 60mA. So it means the keyboard uses significantly less than 500mA, which means it's not the problem. WebAug 11, 2024 · First thing to understand, is that in order for host to convert USB device into UART port it needs device driver that knows exact protocol used by device. Just because your device appears as virtual serial port does not mean it uses some universally recognized protocol. For example many USB-to-UART chips, including very common FT232R, do … WebConnect keyboard to arduino using Mini USB Host Shield Circuit Breaker 2.17K subscribers 16K views 2 years ago I bought a cheap module labelled HW-244 on ebay.
