Make Raspberry Pi HATs Wireless & Run Multiple Raspberry Pi HATs Without Multistacking - By Jyoti Singh

Connect Multiple Raspberry pi HAT Wirelessly Without Multistacking with PiSquare

 The 40-pin connections that allow extension boards known as HATs to be connected to Raspberry Pi's compact and affordable single-board computers are one of the features that make them fascinating (which stands for Hardware Attached on Top). Sensors, displays, extra ports and various I/O possibilities, and much more may be added.

However, because HATs require a physical connection to the Raspberry Pi and completely cover the computer, you can usually only use one at a time. The creators of the new PiSquare have devised a method for allowing you to utilize many HATs at the same time: they've made them wireless.

PiSquare is a tiny board that allows any HAT to be turned into a wireless add-on for a Raspberry Pi. Simply put the HAT into the PiSquare board's 40-pin socket, and instead of connecting it to the Raspberry Pi directly, you may connect it across a WiFi network.

This allows you to connect numerous HATs at the same time using multiple PiSquare boards, eliminating the need to physically stack HATs on top of one another. It also allows you to connect two or more of the same HAT to a Raspberry Pi, which isn't feasible otherwise.

PiSquares will eventually sell for £20 ($26) each, but you can reserve one now for £9 ($12) through a Kickstarter crowdfunding effort. After the campaign closes in May, production will commence, and PiSquare boards will begin delivering in June 2022 assuming all goes according to plan.

A Raspberry Pi RP2040 microprocessor and ESP-12E 802.11b/g/n (WiFi 4) controller, as well as a 0.91-inch OLED display, 16MB of flash, and a USB Type-C connection, are all included on the PiSquare board.

It should work with any Raspberry Pi device that has WiFi capability. As a server, you can utilise either a Raspberry Pi or a PiSquare board, allowing you to accomplish things like:

Connecting the PiSquare to the same wireless network as a Raspberry Pi or other devices like your smartphone allows you to accomplish most of these things. However, you may utilise a Raspberry Pi or PiSquare as a hotspot to make a direct device-to-device connection.

While there is always some risk with crowdfunding initiatives, the PiSquare comes from developer Jyoti Singh, who has already led two successful Raspberry Pi-related Kickstarter campaigns.
