There's also 3 LEDs that you can control over the SPI interface (part of the library code) or you can have controlled by the Arduino library

the solar power management module can allow electrical devices to be charged solely by solar power without the need for frequent battery replacements

DS1337 real time clock

216K Block RAM supports following memory configurations* 8 channels with 24K sample depth

so the effective range is 10cm to 1

30:1 Metal Gearmotor 37Dx68L mm 12V with 64 CPR Encoder (Helical Pinion) Category_Sensors/Light/Imaging There's also 3 LEDs thatThis gearmotor is a powerful 12V brushed DC motor with a 30: 1 metal gearbox and an integrated quadrature encoder that provides a resolution of 64 counts per revolution of the motor shaft, which corresponds to 1920 counts per revolution of the gearbox's output shaft. The gearbox is composed mainly of spur gears, but it features helical gears for the first stage for reduced noise and improved efficiency. These units have a 16 mm long, 6 mm diameter D
