Three-axis accelerometer module with MMA8452 system; I2C bus

Color Sensor Module, TCS3200, LEDs, RoHs

This sensor communicates over I2C or SPI (our library code supports both) so you can share it with a bunch of other sensors on the same I2C bus. Adafruit 2809

A miniature lidar distance sensor that detects objects up to 100 cm away, regardless of color, transparency, or lighting. It generates a digital signal (0 V on detection), operates in the 3-5.5 V range, draws only 30 mA, and supports sleep mode via the ENABLE pin. Ideal for robotics, automation, and contactless interfaces, it offers a fast response time (100 Hz), switching hysteresis, and a compact housing with an indicator LED. Pololu 5483
