Adafruit PyPortal Titano

Overview

The Adafruit PyPortal Titano is the largest member of Adafruit's PyPortal family — an all-in-one IoT display platform designed to let you build internet-connected dashboards, information displays, and control panels with CircuitPython and almost no wiring. The "Titano" variant doubles the pixel count of the original PyPortal with its 3.5-inch 320×480 resistive touchscreen TFT, giving projects noticeably more real estate for data visualizations, web dashboards, and interactive GUIs.

The board uses a dual-chip architecture: an Atmel ATSAMD51J20 ARM Cortex-M4F handles the application logic and runs CircuitPython, while a dedicated Espressif ESP32 acts as a TLS/SSL-capable WiFi coprocessor. This design means the ESP32 handles all the cryptographic overhead of HTTPS connections, keeping the SAMD51 free for display rendering and user-interface work. Connectivity to online APIs for weather, news, stocks, sports, and custom IoT data is handled through Adafruit's adafruit_requests library.

Onboard storage consists of 8MB of SPI Flash for code and assets, plus a microSD card slot for additional images and data files. A built-in speaker and light sensor complement the display. Two I2C plug-in ports (STEMMA QT) allow sensors to be connected without soldering, and two digital/analog GPIO pins extend the board's functionality. The USB-C connector supports both power and programming.

The PyPortal Titano is a consumer-ready, open-source product. All CircuitPython libraries and example code are freely available on GitHub, and the hardware schematics are published on Adafruit's learn platform.
