Product description: PiSquare - module with RP2040 and ESP-12E with support for HAT overlays - SB Components SKU24186
PiSquare is a board based on the Raspberry Pi RP2040 and ESP8266 EPS-12E microcontroller. The module has outputs compatible with Raspberry Pi minicomputers, so you can connect to it Raspberry Pi HAT . Thanks to the ESP-12E system, it is possible to communicate between the PiSquare module and another PiSquare module, Raspberry Pi, computer or cloud via WiFi communication. This solution allows you to connect more overlays for the Raspberry Pi.
PiSquare - RP2040 and ESP-12E module with Raspberry Pi 40-pin pins.
PiSquare supports HAT overlays.Main features of PiSquare

PiSquare can work as both a server and a client.PiSquare board operating modes
- Raspberry Pi as a server, PiSquare as a client and vice-versa - work with multiple HATs at the same time (connect multiple HATs to Raspberry Pi [Master]).
- PiSquare as the client and PiSquare as the server and vice-versa (connect multiple HATs to PiSquare [Master]).
- Smartphone as a server, and PiSquare modules as a client and vice-versa - run any HAT overlay on a single PiSquare and control it from your smartphone (connect multiple overlays with your phone / tablet [Master]).
- Create a Hotspot on Raspberry Pi (Master) and connect multiple HATs to it (no router needed).
- Create a Hotspot on PiSquare (Master) and connect multiple HATs to it (no router needed).
