Thanks to the ATMEGA328 microcontroller, which features series interface, 23 GPIOS too SPI series port, the GoPiGo board tin communicate amongst figurer hardware too software. That's where a unmarried board figurer similar the Raspberry Pi comes inwards handy beingness the size of a palm. The Raspberry Pi fits nicely on last on of the GoPiGo board, connecting amongst ane roughly other via I2C interface too enabling the communication of commands to the GoPiGo's encephalon (the ATMEGA328 microcontroller).
There are several analog too digital ports on the GoPiGo board for connecting sensors similar temperature, accelerometer too GPS. On the dorsum of the board is where the microcontroller is located, every bit good every bit ii Optical Encoders amongst xviii pulse counts per rotation which assistance the GoPiGo deed exactly inwards a lead line.
Raspberry Pi Model B+The GoPiGo board operates amongst voltages betwixt 7V too 12V; thence the battery pack carrying viii 1.5V batteries to ability both motors, ultrasonic sensor, servo too Raspberry Pi (the Raspberry Pi itself uses 3.3V).
