IO Expansion HAT for Raspberry Pi 5 / 4B / 3B+ (DFR0566)

IO Expansion HAT for Raspberry Pi 5 / 4B / 3B+ (DFR0566) — DFRobot — DFR0566

Gravity-compatible expansion HAT for Raspberry Pi 5, 4B, and 3B+ (65×56 mm) adding digital, analog, PWM, I2C, UART, SPI, and I2S interfaces. Sensor ports run at 3.3 V logic on 5 V supply; a 6–12 V external input powers servo outputs.
