Key Improvements from Pi 2 Model B to Pi 3 Model B:

Next Generation QUAD Core Broadcom BCM2837 64bit processor

Processor speed has increased from 900MHz on Pi 2 to 1.2Ghz

BCM43438 WiFi on board

Bluetooth Low Energy (BLE) on board

Upgraded switched power source up to 2.5 Amps (can now power even more powerful devices over USB ports)

 

Other Technical Specification:

40pin extended GPIO

4 x USB 2 ports

4 pole Stereo output and Composite video port

Full size HDMI output

CSI camera port for connecting the Raspberry Pi cameraRaspberry Pi camera

DSI display port for connecting the Raspberry Pi touch screen displayRaspberry Pi touch screen display

Micro SD port for loading your operating system and storing data

Upgraded switched Micro USB power source (now supports up to 2.5 Amps)

The same form factor as the Pi 2 Model BPi 2 Model B, - the only difference is the location of the onboard LEDs

  • hello friends, i am using rpi 3 for serial communication with my communicating device which works at 300 baud rate with computer. But when i access my device with rpi 3 with putty software ( on serial port only) it gives garbage value. why is it so? please help.

  • in reply to rdcell@141

    Roger may very well be correct that the Pi does not go that low. I have not tried it, but there are more things at play than just baud rate, if it can do 300 baud.

     

    There are also start bits, stop bits and parity settings that must match on both sides. You'll often see this denoted as 8N1, which would be 8 data bits, 1 stop bit and no parity. Check the settings on both sides and make sure they are the same.

    Most modern telecommunications programs, such as putty,  will allow you to change the values to match. If your framing is off, your data wil be garbage, even if the baud rate is the same.

     

    Also, realize the pi puts out data at ttl levels, many data communications devices expect to see levels of +12v for a 1 and -12v for a zero.
