PocketBeagle 2 SBC combines TI AM6232 dual-core Cortex-A53 SoC with MSPM0 MCU

Beagleboard has recently announced the PocketBeagle 2, a single board computer (SBC) built around TI’s AM6232 dual-core Cortex-A53 and Cortex-M4F SoC and an additional MSPM0L1105 Arm Cortex-M0+ microcontroller for ADC pins and board ID storage. Designed for developers, students, and hobbyists, it’s a direct upgrade from the previous generation PocketBeagle which the company released in 2017. The new board comes with a faster dual-core 64-bit CPU (compared to a single-core CPU), faster memory (DDR4), improved power management (USB-C + LiPo charger), and easier debugging (UART + JTAG) for faster development. Additionally, it comes with four user-controllable LEDs, a power LED, and a battery-charging LED for better status indication. Unlike the first generation, this new version comes with pre-soldered GPIO headers with the same compact (55 x 35mm) form factor, making it suitable for embedded applications and IoT projects. PocketBeagle 2 single-board computer specifications Main SoC – Texas Instruments AM6232 CPU […]

AquaPing is an open-source, battery powered acoustic water leak detector module (Crowdfunding)

The AquaPing is an open-source hardware, ultra-low power acoustic water leak detector sensor based on Texas Instruments MSP430 microcontroller and a microphone that can detect leaks without having to do any plumbing, instead capturing audio for water leak detection, and it even works for leaks behind walls. All signal processing and analysis occur on the MSP430 MCU, so no audio is streamed to the cloud and eavesdropping is impossible, plus the sensor only captures high frequencies out of the range of normal conversations, so eavesdropping is not feasible, plus those higher frequencies are also said to provide highest sensitivity and reliability. AquaPing specifications: MCU – Texas Instruments MSP430FR5994 microcontroller to perform FFT spectral analysis (10x faster/efficient than ARM-Cortex M0+) Audio capture – MEMS microphone covered by a small rectangular plastic structure to form a Helmholtz resonator. Minimum detectable leak rate – 0.01 gpm (gallon per minute) depending on stand-off distance […]
