BeagleBoard BeagleBone Black review

The BeagleBone Black is built around the TI Sitara AM3358: a 1 GHz ARM Cortex-A8 with SGX 3D graphics, NEON and two 200 MHz PRUs. It has 512 MB of DDR3L at 800 MHz. The two 46-pin expansion headers carry LCD, UART, eMMC, ADC, I2C, SPI and PWM signals, which points at embedded and hardware projects rather than desktop use or heavy server work.

The manufacturer page lists Debian 13.7 and 12.15 images. It also lists three kernel branches: v6.18.x, v6.12.x and v5.10-ti. That gives you a choice of two Debian releases and several kernel lines from the board's own maker, which counts for a lot when you want a supported base for a long-running project.

The CPU is a 1 GHz Cortex-A8, paired with 512 MB of RAM. The SoC also includes NEON and SGX 3D graphics. One buyer's guide calls 512 MB tight for modern desktop use. With 512 MB of RAM and one Cortex-A8, the board suits a single service, a controller or a gateway better than a stack of containers.

A 2012-era comparison puts it ahead of the Raspberry Pi Model B on performance and power consumption, but says it runs about 5°C hotter.

The two PRUs run at 200 MHz and sit on the same SoC. For projects built around the PWM, SPI and I2C signals on the headers, they are part of the hardware you get.

The board has 4 GB of 8-bit eMMC onboard and a microSD connector. The 4 GB capacity is small, and the microSD connector is the only other storage listed. Nothing in the specifications offers NVMe or PCIe storage.

Ethernet is 10/100 Mbit over RJ45. There is no Wi-Fi or Bluetooth on this board, and owners flag the slow Ethernet and missing wireless. A separate Wireless variant swaps Ethernet for 802.11b/g/n and Bluetooth 4.1, but it is a different product with a different connection set.

The USB host port is limited to 500 mA. If you plan to power peripherals from it, check their draw first.

Video comes from HDMI, with stereo audio over HDMI, and there is also an LCD interface. Power arrives through a 2.1 mm barrel jack or mini-USB at 5 V, and a 1 A supply is typical.

A TI forum developer reports that HDMI and LAN stay active in deep sleep mode. That matters if you are designing around low power, because those interfaces will not be off while the board sleeps.

It suits builders who want a documented board with official Debian images, onboard eMMC and generous header options. The 512 MB of RAM and 10/100 Ethernet limit it for anything network-heavy or memory-hungry. Choose it for the headers, the PRUs and the vendor-listed software, not for raw speed.
