The Best Raspberry Pi Alternatives in 2021

Author: Robert Wilson

Electronics & Peripherals Expert

A single-board computer has been developed by the British foundation Raspberry Pi. It contains a single-chip SoC system with an ARM CPU. The shape of the board resembles a credit card. Raspberry Pi has been on the market since 2012 with great success. The device is widely used as a media center with HD resolution and HDMI interface.

The operating system used is mainly Linux with a graphical user interface. However, the latest models also have Windows 10. The system is booted via a removable SD card. The latest models can also be booted via USB mass storage or network.

Banana Bi M3

The Banana Bi M3 is a single-board computer with 2 GB of RAM and an octa-core processor. Furthermore, a Gigabit Ethernet, SATA, WiFi, 2 USB, Bluetooth and HDMI connections are present.

The computer can work with a variety of systems such as Android, Ubuntu, Raspbian, Debian and Lubuntu. BPI is an open platform for all developers, entrepreneurs, do-it-yourselfers, tech enthusiasts and others with the support of a wide community. The M3 masters the art of octa-core and has a SATA port to connect to a hard drive.

Main features of the BPI M3

  • Allwinner A83T Octa-Core 1.8 GHz powerful CPU,
  • HDMI,
  • 2 GB LPDDR3 memory,
  • 8 GB eMMC memory,
  • IR control,
  • MIPI DSI interface,
  • WiFi & Bluetooth on board,
  • CSI camera interface,
  • USB Sata,
  • Powe VR SGX544MP1.

Technical specifications

In brief, the technical specifications are summarized:

  • Power consumption: 5 volts at 2 A,
  • Size, weight: 92 x 60 mm, 48 g,
  • OS: Android and Linux.

Remote control is via an IR receiver (x1). Switches include a reset, power and submarine switch. The BPI-M3 has a 40-pin GPIO header like the Raspberry Pi 3. The CSI camera connection is via a 40-pin FPC connector with an external camera module. This interface is labeled CSI on the board.

The display connector is also a 40-pin FPC connector and is labeled DSI. The software provided is the manual for Android, Linux and possibly Opnewrt or TinaLinux. The hardware interaction is broken down for the Front Side and for the Rear Side.

On the rear side, you can see the connectors for MicroSD card slot and WiFi and BT Antenna (optional). All other ports and components are located on the front. These include HDMI, SATA, USB, Enternet Interface, Display Interface and other components.

What is needed for a quick start?

When operating the computer for the first time, the following items are required: a micro SD card, HDMI, a keyboard or mouse, an Ethernet cable, a micro USB power adapter, an audio cable, and a mobile hard drive. The minimum size for the optional SD card should be 8 GB.

Any standard USB keyboard or mouse should work. For storage, a mobile hard drive to the USB port is suitable. Other basics needed are a BPI-SBC, a class 10 or higher MicroSD card, a power adapter with 5V/2A power supply, a host computer running Ubuntu 64, and a serial communication card.

The operating system image is loaded onto the formatted SD card, which is then used to set up the operating system. Once everything is properly connected, the system boots and the screen displays the OS GUI.
