Overview

The Beagle-Pi is a passive adapter that lets you replace a Raspberry Pi with a BeagleBone Black, while keeping every Raspberry Pi HAT you already own.

  • Maps all Raspberry Pi GPIO pins to the corresponding BeagleBone Black pins
  • Maps I2C, SPI and UART to the corresponding BeagleBone ports
  • Brings out the BeagleBone serial debug connector
  • Includes a 30-pin FFC connector for an external display
  • Runs all Raspberry Pi software: Command line, Python, Node-RED
  • No SD card needed! Runs Linux on internal flash.
  • Ambient operating temperature: -40°C to 85°C

Works with Open Automation Software

The BeagleBone Black runs the same software stack as a Raspberry Pi, so any Command Line, Python, or Node-RED project you've already built keeps working.

• Ambient operating temperature: -40°C to 85°C

DESCRIPTION

BeagleBone cards are readily available, from $50 to $100. They have lots of GPIO pins, I2C, SPI and serial interfaces, and run Linux and Node-RED — so they can run all the same software as a Raspberry Pi. The Beagle-Pi is a passive adapter which maps all the Raspberry Pi GPIO pins to the corresponding pins on the BeagleBone Black interface.

GPIO Pin Mapping

All Raspberry Pi GPIO connector (J1) pins are mapped 1:1 to the corresponding BeagleBone Black pins. Any I/O board designed for the Raspberry Pi can be plugged into the Beagle-Pi adapter.

I2C, SPI & UART Mapping

The I2C, SPI and serial ports are mapped to the identical interfaces on the BeagleBone. PWM-capable pins on the GPIO connector are connected to PWM-capable pins on the BeagleBone.

Serial Debug & Display Connectors

Connector J3 brings out the BeagleBone's serial debug port, and connector J2 brings out its display port through a 30-pin FFC connector for an external display.

No SD Card Required

The BeagleBone Black runs Linux directly from its internal flash memory, so no SD card is needed to boot or operate the system.

Power Source Selection

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

TECHNICAL DETAILS

CARD LAYOUT

RaspberryPi Replacement using BeagleBone Black

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

GPIO MAP

The table below shows the correspondence between the Raspberry Pi GPIO pins and the BeagleBone pins.

POWER REQUIREMENTS

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

DEBUG & DISPLAY CONNECTORS

Connector J3 brings out the serial debug port of the BeagleBone. Connector J2 brings out the display port of the BeagleBone through a 30-pin FFC connector, for connecting an external display.

QUICK START

  1. Plug the Beagle-Pi board onto the BeagleBone Black using the P8 and P9 connectors, and power up the system.
  2. To temporarily enable I2C on the BeagleBone, open a terminal and type: config-pin P9.17 i2c and config-pin P9.18 i2c. Depending on your OS, you might have to use config-pin p9-17 i2c and config-pin p9-18 i2c instead.
  3. To enable I2C permanently at startup, edit the file /etc/rc.local and add the same two lines above the exit 0 line.
  4. To use Node-RED, which comes preinstalled on the BeagleBone, add Node-RED to the I2C group: sudo usermod -a -G i2c node-red.
  5. The Raspberry Pi serial port on GPIO pins 8 and 10 is mapped to the BeagleBone UART4, which can be enabled by adding the following lines to /etc/rc.local: config-pin p9.11 uart and config-pin p9.13 uart. Restart the BeagleBone after changing the file.
  6. To check the available serial ports, type: dmesg | grep tty.
