While adding wireless connectivity to your Raspberry Pi Pico is a good concept, Pico WiFi HAT connects to the back of your Pi and utilises an ESP8266 high integration wireless SoC to connect to 2.4GHz wireless networks and transmit data. Pico WiFi HAT also includes a 1.14-inch display with a resolution of 240 x 135 pixels, 65K RGB colours, and a sharp and vivid exhibiting effect, designed primarily for user engagement via SPI connection by incorporating a GPIO header.
The ST7789 Driver and SPI Interface are included in the 1.14-inch LCD, reducing the number of IO pins required. It also has two reset buttons and a flash button that may be used to upgrade the firmware on the ESP8266 WiFi Chip.
Pico WiFi HAT is ideal for easily adding wireless capabilities to an existing Pico project, such as transmitting sensor data into home automation systems or dashboards, hosting a web page from a matchbox, or allowing your Pico to communicate with internet APIs.
It comes with female headers that allow it to be plugged directly into the Raspberry Pi Pico's rear, as seen above, or into a "Pico 2 Channel expander & 4 Channel expander" board, as shown below.
Because WiFi is controlled by a different chip, your code is easier to write because you don't have to cache socket data or develop and debug an SSL library. Pico Wifi allows you to transmit basic yet strong socket-based commands for high-speed data transmission via 2.4GHz SPI. The ESP8266 can handle all of the hard lifting of connecting to a WiFi network and transmitting data from a site, utilising the most up-to-date WEP64 / WEP128 / TKIP / AES encryption with IPv4, TCP / UDP / FTP / HTTP Network Protocol.
All Pico Wi-Fi HATs come with AT firmware preloaded, allowing you to build and design your projects without having to update the AT firmware for the ESp8266.
