M5Stack Tab5 Review – Part 2: Getting started with ESP32-P4 firmware development using the ESP-IDF Framework and Arduino IDE

In the first part of the review, we checked out the hardware of the M5Stack Tab5 ESP32-P4 IoT development kit and tried the demo firmware, whose user interface allows the user to quickly experiment with the camera, microphone, speaker, WiFi, power consumption, GPIOs, RS485, and more. Since there’s no user application for the Tab5 at this stage, I decided to look into software development resources for the ESP32-P4 devkit in the second part of the review. I’ll first follow the instructions to build the demo firmware from source using the ESP-IDF framework, then analyze key aspects of the source and make some small modifications. After that, I’ll have a look at ESP32-P4 Arduino support via M5Unified and M5GFX library. ESP-IDF 5.4.1 installation and ESP32-P4 Hello World program The first step is to get the ESP-IDF 5.4.1 and configure ESP32-P4 following the instructions on the Espressif website, before testing it with […]

TexHoo QN15 – A sub $100 mini PC with Intel Processor N150 CPU

Once entry-level Intel processors have been on the market for long enough, we often start to see systems sell for under $100. The TexHoo QN15 mini PC is offered with a recent Intel Processor N150 Twin Lake CPU for just around $100 in its barebone configuration with WiFi 5, but no RAM, and no storage. The mini PC supports DDR4 memory and NVMe and SATA storage, and offers two 4K-capable HDMI ports, gigabit Ethernet, a M.2 socket for WiFi and Bluetooth, and five USB ports with two USB 3.2, two USB 2.0, and a USB Type-C port. TexHoo QN15 specifications: SoC – Intel Processor N150 quad-core Twin Lake processor @ up to 3.6 GHz (Turbo) with 6MB cache, 24EU Intel UHD graphics @ 1.0 GHz; TDP: 6W System Memory – SO-DIMM socket for DDR4-2666/32000 up to 32GB Storage M.2 2280 socket for SATA or NVMe SSD 2.5-inch SATA bay (proprietary SATA […]

Arm introduces new product naming architecture for infrastructure, PC, mobile, automotive, and IoT

arm product naming: neoverse lumex niva zena orbis

We all know that Arm Cortex-A are application cores, Cortex-M microcontroller-class cores, and Cortex-R real-time cores used in various applications from IoT to automotive or architecture. But this may soon be thrown out of the window, as Rene Haas, Arm CEO, has published a short post entitled “The Arm Evolution: From IP to Platform for the AI Era” introducing a new product naming architecture with five categories: Arm Neoverse for infrastructure Arm Niva for PC Arm Lumex for mobile Arm Zena for automotive Arm Orbis for IoT While it’s not explicitly stated in the post, I assume that means the Cortex naming goes away because we’re told the Mali brand will continue as the GPU brand, and the Arm Neoverse N1, based on Cortex-A76, is an example where Cortex branding is not used anymore. So I understand, they just decided to apply similar naming to all the product lines, although […]
