Robot HATS
Robot HATS is a specially-designed HAT for a 40-pin Raspberry Pi and can work with Raspberry
Pi model B+, 2 model B, and 3 model B. It supplies power to the Raspberry Pi from the GPIO
ports. Thanks to the design of the ideal diode based on the rules of HATS, it can supply the
Raspberry Pi via both the USB cable and the DC port thus protecting it from damaging the TF
card caused by batteries running out of power. The PCF8591 is used as the ADC chip, with I2C
communication, and the address 0x48.
