BeagleBoard.org has unveiled the PocketBeagle 2, a compact single-board computer (SBC) that integrates Texas Instruments' AM6232 dual-core Cortex-A53 SoC and an MSPM0L1105 Arm Cortex-M0+ microcontroller. This release marks a significant upgrade from the original PocketBeagle introduced in 2017, offering enhanced processing power, improved memory, and advanced debugging capabilities.
PocketBeagle 2 single-board computer specifications
- Processing Power: Equipped with a dual-core 64-bit Arm Cortex-A53 processor running at 1.0 GHz and an Arm Cortex-M4F real-time core at 400 MHz, the PocketBeagle 2 ensures efficient performance for a variety of applications.
- Secondary Microcontroller: The onboard MSPM0L1105 microcontroller operates at 32 MHz, providing 32KB flash memory, 4KB SRAM, and a 12-bit ADC, facilitating precise analog signal processing.
- Memory and Storage: The SBC comes with 512 MB LPDDR4 SDRAM clocked at 3200 MHz and includes a microSD card slot compatible with both 1.8V and 3.3V cards for expandable storage options.
- Connectivity and Expansion: A USB Type-C port serves both power and data transfer functions. The 72-pin expansion headers offer access to 8 analog inputs, 52 digital I/Os, high-speed USB, and various digital interface peripherals, enabling extensive customization.
- Debugging and Indicators: Features include a UART port compatible with Raspberry Pi Debug Probe for seamless debugging, a 10-pin JTAG TAG-CONNECT footprint, a power button, user/boot button, and multiple LED indicators for power, battery charging, and user-defined functions.
- Power Management: The device supports a 5V/1A input via USB-C, an alternative power input through the Cape Header VIN, and incorporates a built-in LiPo battery charger, ensuring versatile power solutions.
Measuring 55 x 35 mm and weighing 12.7 grams, the PocketBeagle 2 maintains a compact form factor suitable for embedded applications and IoT projects. Notably, while the specifications do not list onboard eMMC flash storage, the board's design includes a footprint for a 4GB eMMC flash, indicating potential for future enhancements.
For software support, BeagleBoard.org provides Debian-based distributions tailored for the PocketBeagle 2. Users can download the latest Debian 12.9 (Minimal) image, released on February 7, 2025, from the official BeagleBoard website. As an open-source hardware platform, comprehensive documentation, including schematics and board files, is accessible on the BeagleBoard documentation page.
The PocketBeagle 2's enhanced capabilities and open-source nature make it an excellent choice for developers, hobbyists, and students aiming to explore and innovate in the realm of embedded systems and IoT solutions.
The PocketBeagle 2 is now available on Digikey and Mouser for $29.00. The official product page may have more information.
