Raspberry Pi Emulator using Beagle Bone Black

Raspberry Pi has been the flag-bearer of the low cost single board computers for many years. Except the last few years, of course. 

Two years ago you could purchase a Raspberry Pi 3B+ for $35. Now you can buy it on Amazon for $150. If you are lucky. Mouser is quoting a ridiculous 78 weeks lead time.

On the other hand, Beagle Bone cards seem to be readily available, from $50 to $100. They have lots of GPIO pins, I2C, SPI and serial interfaces. The boards run Linux and Node-RED, and could run all Raspberry Pi software.

The Beagle-Pi is a passive adapter which maps all the Raspberry Pi GPIO pins to corresponding pins on the Beagle Bone Black interface. The I2C, SPI and serial ports are mapped to the identical interfaces. The other I/O pins are mapped 1 to 1. PWM pins on the GPIO connector are connected to PWM capable pins on the Beagle Bone.


RaspberryPi Replacement using BeagleBone Black

The board plugs into the Beagle Bone Black board using P8 and P9 connectors, and emulates the Raspberry Pi GPIO connector J1. Any IO board designed for Raspberry Pi can be plugged into the Beagle Pi adapter. The adapter mounts on the Beagle Bone card using the four outside holes. Raspberry Pi HATs can be plugged into the J1 connector and secured using the four inside holes. 

Connector J5 selects the source of power for the BeagleBone, from the barrel or the USB connector.

Connector J3 brings out the serial debug port, and J2 brings out the display port of the BeagleBone.


The tables bellow shows the correspondence between the Raspberry Pi GPIO pins and the Beagle Bone pins.

All the Sequent Microsystems drivers have been compiled for Beagle Bone and can be downloaded from GitHub. GPIO pin mapping commands will be available soon.

To temporarily enable the I2C on Beagle Bone, open a terminal and type the following commands:
config-pin P9.17 i2c
config-pin P9.18 i2c
Depending on your OS, you might have to use the commands:
config-pin p9-17 i2c
config-pin p9-18 i2c
To enable the I2C permanently at startup, edit the file /etc/rc.local and add the same two lines. All the command "exit 0" on the last line.
To use the Node-RED, which comes preinstalled on the Beagle, add the Node-RED to the I2C group with the command:

sudo usermod -a -G i2c node-red

The Raspberry Pi serial port on GPIO pins 8 and 10 is mapped to the Beagle UART4, which can be enabled by adding the following lines to the "etc/rc.local" file:
config-pin p9.11 uart
config-pin p9.13 uart
Restart the Beagle after changing the "etc/rc.local" file.
To check the available serial ports type the command:
dmesg | grep tty
