That’s kinda mean. The Arduino already has a socket and a board. Just the ATMega328 is 5,65 euro. For 21 IO pins, that’s 0.26 euro per IO. The MCP23S08 is 1,32 euro, so 0.17 euro per IO.

The chip expects 3.3 V logic so he made use of a MC74LVX50 hex buffer to tailor the Arduino’s 5 V. Currently he’s working on revision two of the shield, which will include SPI flash memory.

The shield’s specifications include a 3.97” display with a resolution of 480×800 RGB, 16.7M color, five points and gestures touch mode, an I2C interface, a BMI270 IMU sensor, and an ...

1Sheeld, A Super Clever All-Purpose Arduino Shield, Goes Up On Kickstarter And Immediately Breaks Its Goal. Greg Kumparak. 2:51 PM PST · November 21, 2013.

The Shield itself is getting a quiet upgrade in the process -- the software both takes up a smaller footprint and can now talk to the world in the background while the Arduino keeps on keepin' on.

The Best IoT Arduino Shields to Start 2024 Feb. 12, 2024 The best Arduino shields for IoT applications provide a host of features designed for connectivity, control, and data throughput.

The Giga Display Shield (plug-in board) might fit the bill. It adds a 3.97inch 480 x 800 RGB touchscreen, digital microphone (MP34DT06JTR by ST), six-axis IMU (Bosch BMI270 inertial measurement unit), ...

The associated demonstration code continually streams increasing integer values through the Arduino UART to the transmitter, and receives them back via the fibre link. “To show this running, we put a ...
