Compared to the original PyPortal, the Titano does not include a ADT7410

temperature sensor. It also has a higher-resolution screen with a different

controller chip. The Processor, STEMMA connectors and WiFi have the exact

same wiring as the original 3.2" PyPortal so if you are running

Arduino/CircuitPython code, you'll just have to adjust your graphics and fonts

for the larger resolution screen!

The PyPortal Titano includes: speaker, light sensor, NeoPixel, microSD card slot,

8MB flash, plug-in ports for I2C and 2 analog/digital pins. Open-source

hardware, and Open-Source software, CircuitPython and Arduino. The device

shows up as a USB drive and the code (Python) can be edited in any IDE, text

editor, etc.

The M4 and ESP32 are a great couple - and each bring their own strengths to

this board. The SAMD51 M4 has native USB so it can show up like a disk drive,

act as a MIDI or HID keyboard/mouse, and of course bootload and debug over a

serial port. It also has DACs, ADC, PWM, and tons of GPIO. Meanwhile, the ESP32

has secure WiFi capabilities, and plenty of Flash and RAM to buffer sockets. By

letting the ESP32 focus on the complex TLS/SSL computation and socket

buffering, it frees up the SAMD51 to act as the user interface. You get a great

programming experience thanks to the native USB with files available for drag-

n-drop, and you don't have to spend a ton of processor time and memory to do

SSL encryption/decryption and certificate management. It's the best of both

worlds!
