PiSquare turns Raspberry Pi HATs into wirelessly accessible gadgets.

Connect Multiple Raspberry Pi HATs Wirelessly Without Multistacking - Smart Solution Introduced by Jyoti Singh Collaboration with Tech Company SB Components and Also a Raspberry Pi Approved Design Partner.

The PiSquare can function without a Raspberry Pi at all, as well as attach numerous HATs to a single Raspberry Pi through Wi-Fi.

Engineer Jyoti Singh and SB Components have collaborated to make it feasible to operate Raspberry Pi HAT add-ons wirelessly, allowing you to attach as many HATs as you like to a single driving system, even if they're duplicates or have the same pin functionality.

"PiSquare uses Socket programming to wirelessly connect Multiple ('n' numbers of HATs) Raspberry Pi HATs," Singh says of his work, which is intended for use with Raspberry Pi Hardware Attached on Top (HAT) add-ons. "You can make a server out of a Raspberry Pi and run as many HATs as you want as a client to run multiple Raspberry Pi HATs with PiSquare."

A Raspberry Pi RP2040 microcontroller, a Espressif ESP8266-based ESP-12E microcontroller module with on-board Wi-Fi connectivity, a USB Type-C port for power, a 0.91" OLED display, and 16Mb (2MB) of flash memory — plus a 40-pin general-purpose input/output (GPIO) header to accept the HAT — make up the PiSquare board.

The PiSquare is designed to connect numerous HATs to a single Raspberry Pi in its most basic configuration. Unlike previous multi-HAT systems, each HAT can be controlled individually, which means you may use a single PiSquare to control many hats that all utilise the same I2C address or UART connection, for example.

The board has a second purpose, according to Singh, and it's one that might help alleviate the existing Raspberry Pi scarcity. "You can also make the PiSquare [...] a master for all the other PiSquare [boards]," Singh continues, "[or] run any HAT on a single PiSquare and control it via your phone," implying that a Raspberry Pi isn't required at all.

Singh's Raspberry Pi add-on isn't his first: He released the PiRelay 8, an eight-relay extension board with integrated display for the Raspberry Pi's GPIO interface, in July 2021, and the PicoCube, a single-color 444 LED cube for the Raspberry Pi Pico, in October of the same year. Both initiatives were successful in raising funds.

The PiSquare board's Kickstarter campaign is now online, beginning at £9 (about $12) for a single PiSquare. Hardware is slated to start delivering in June, with a suggested retail price of £20 (about $26).
