Wire (I2C)

(inherits from Stream)

This object allows you to communicate with I2C / TWI (Two Wire Interface) devices. For an in-depth tutorial on I2C, see learn more about I2C.

Interface Maximum Speed (Gen2) Maximum Speed (Gen 3) Maximum Peripheral Devices
UART Serial 230 Kbit/sec 1 Mbit/sec 1 (point-to-point)
I2C 400 Kbit/sec 400 Kbit/sec Many (limited by addresses)
SPI 60 Mbit/sec 32 Mbit/sec Many (limited by CS GPIO pins)
