The Raspberry Pi’s venerable 40-pin header and related HAT ecosystem for updates has been a boon for the system. It’s uncomplicated to stack additional components on to a Pi, even a number of periods in some conditions. However, if you want to operate various HATs, and wirelessly at that, the PiSquare could just be the matter for you.
The PiSquare consists of a board showcasing both RP2040 and ESP-12E microcontrollers. It interfaces with Raspberry Pi HATs and even allows you run various of the very same HAT on a solitary Raspberry Pi, as it is not really specifically working with the UART, SPI, or I2C interfaces on the host Pi by itself. Rather, the PiSquare communicates wirelessly with the Pi, dealing with the IO with the HAT alone.
It’s unclear how this functions on a program stage. Simply just working with existing computer software applications and libraries for a given Raspberry Pi HAT almost certainly will not operate with the wi-fi PiSquare set up. Having said that, for innovative buyers, it could serve a valuable goal, permitting one particular Raspberry Pi to command various HATs with no the fuss of obtaining to operate much more solitary-board computers where by just one particular will do. Boards will be readily available on Kickstarter for individuals interested in the system.
We’ve observed other innovative issues carried out with the Raspberry Pi and the HAT process, also. If you’ve been cooking up your have neat hacks for the platform, drop us a line!
