Pi Pico Puts Bluetooth Keyboards On The I2C Bus
The bt2i2c project allows users to connect standard Bluetooth keyboards to microcontrollers via the I2C bus using a Raspberry Pi Pico W. This innovation simplifies hardware integration for DIY projects and 'writerdeck' builds.
Why it matters
It provides a practical, low-cost solution for hobbyists and engineers to interface modern wireless peripherals with legacy or embedded hardware.
If you ve ever worked with I2C, you know its one of those things that makes working with modern microcontrollers such a pleasure. With a few wires and not many more lines of code, you can communicate with all sorts of hardware such as sensors, displays, and input devices. There are even I2C keyboards out there, although they tend to be a bit pokey and not in the good way as it pertains to keyboards.
