Hardware Introduction¶
- Left/Right Motor Port
2-channel XH2.54 motor ports.
The left port is connected to GPIO 4 and the right port is connected to GPIO 5.
API: class Motor - motor control,
0for left motor port,1for right motor port.
- I2C Pin
2-channel I2C pins from Raspberry Pi.
API: class i2c - IIC Bus
- PWM Pin
12-channel PWM pins, P0-P12.
- ADC Pin
4-channel ADC pins, A0-A3.
- Digital Pin
4-channel digital pins, D0-D3.
- Battery Indicator
Two LEDs light up when the voltage is higher than 7.8V.
One LED lights up in the 6.7V to 7.8V range.
Below 6.7V, both LEDs turn off.
- LED
Set by your program. (Outputting 1 turns the LED on; Outputting 0 turns it off.)
API: class Pin - control I/O pins, you can use
Pin("LED")to define it.
- RST Button
Short pressing RST Button causes program resetting.
Long press RST Button till the LED lights up then release, and you will disconnect the Bluetooth.
- USR Button
The functions of USR Button can be set by your programming. (Pressing down leads to a input “0”; releasing produces a input “1”. )
API: class Pin - control I/O pins, you can use
Pin("SW")to define it.
- Power Switch
Turn on/off the power of the robot HAT.
When you connect power to the power port, the Raspberry Pi will boot up. However, you will need to switch the power switch to ON to enable Robot HAT.
- Power Port
7-12V PH2.0 2pin power input.
Powering the Raspberry Pi and Robot HAT at the same time.
- Bluetooth Module
Since the Raspberry Pi comes with Bluetooth in slave mode, there will be pairing problems when connecting with cell phones. To make it easier for the Raspberry Pi to connect to the Ezblock Studio, we added a separate Bluetooth module.
Ezblock Studio is a custom graphical programming application developed by SunFounder for Raspberry Pi, for more information please refer to: Ezblock Studio 3.
- Bluetooth Indicator
The Bluetooth indicator keeps turning on at a well Bluetooth connection, blink at a Bluetooth disconnection, blink fast at a signal transmission.
