Linux Gizmos ☛ DigiPort Pocket PC Built with Raspberry Pi CM4
Kickstarter recently featured the DigiPort, a pocket-sized, open-source computer that transforms any HDMI-compatible screen into a fully functional PC. Powered by a Raspberry Pi Compute Module 4, it provides a versatile solution for various tasks, including programming, gaming, and multimedia streaming.

SparkFun Electronics ☛ Sweet as AI Pi
The AI Camera transparently augments captured still images or video with tensor metadata, leaving the processor in the host Raspberry Pi free to perform other operations. Support for tensor metadata in the libcamera and Picamera2 libraries, and in the rpicam-apps application suite, make it easy for beginners to use, while offering advanced users unparallelled power and flexibility.

CNX Software ☛ Upcoming Rockchip RK3688 Armv9.3 AIoT processor to feature a 16 TOPS NPU, UFS 4.0 interface
Rockchip unveiled the RK3688 AIoT SoC with Armv9.3 Cortex-A7xx cores delivering up to 250K DMIPS (RK3588 delivers 93K DMIPS), a 1 TFLOPS GPU, and a 16 TOPS NPU. The new processor succeeds the Rockchip RK3588 octa-core Cortex-A76/A55 first announced in 2019, and also features a 128-bit LPDDR4/4x/5 memory interface, and a UFS 4.0 storage interface. That’s about all we know about the RK3688 right now, but we can also deduct it’s probably based on a new, yet-to-be-announced Arm Cortex-A7xx core, possibly named Cortex-A730 or Cortex-A735, because no Arm cores have been announced with the Armv9.3 architectures. The Arm Cortex-A725 CPU core unveiled last May still relies on Armv9.2, and I’d expect new Arm cores to be introduced within the next few months unless Rockchip made a mistake in the presentation slide above.
