Adafruit CH9328 UART to HID Keyboard Breakout
Adafruit Industries, LLC mail
The CH9328 is a funky chip that is basically a programmed microcontroller that enumerates as an every-day HID keyboard and can convert ASCII or 8-byte raw reports, read over a standard serial port UART, into keypresses. So, you can emulate a keyboard even if your chip doesn't have native USB! You do need a hardware or software serial port: some way to generate 9600 baud 3V-logic signal that the CH9328 can read.
