AMD Kria K24 Zynq Ultrascale+ system-on-module targets motor control and DSP applications

AMD Kria 24

The AMD Kria K24 System-on-Module (SOM) with a custom-built Zynq UltraScale+ MPSoC and the KD240 Drives Starter Kit are designed for the development of cost-sensitive industrial and commercial edge applications. The new Kria K24 is about half the size of a credit card and uses half the power of the larger, but connector-compatible, Kria K26 SOM that was introduced in 2021 for computer vision applications when the company was still known as Xilinx. That means existing K26 carrier boards can be reused with the Kria K24 SOM without modifying the PCB, but note there’s only one 240-pin connector on the new module, plus an extra 40-pin connector. AMD Kria K24 specifications: MPSoC – Custom-built Zynq Ultrascale+ XCK24 Quad-core Arm Cortex-A53 processor  up to 1.3 GHz Dual-core Arm Cortex-R5F real-time processor up to 533 MHz Mali-400 MP2 GPU up to 600 MHz FPGA fabric with 154K logic cells AMD Deep Learning […]

SunFounder Zeus Car Kit review – A fun toy and Arduino learning tool

Sunfounder Zeus Car Kit Review

SunFounder Zeus Car Kit is an Arduino UNO and ESP32 Cam-based educational kit for children (and adults) that can be used to learn more about electronics, robotics, and programming. It’s a car comprised of four 6cm Mecanum wheels for omnidirectional motion and various sensors that can be controlled with an Android app enabling first-person view (FPV) thanks to the built-in camera. The company sent us a Zeus Car Kit for review and evaluation, and after assembly, we’ll use it in “Play Mode”, or in other words a toy that basically works out of the box, before checking out the “Programing Mode” and related Arduino tutorials to evaluate it’s educational potential. Zeus Car Kit Unboxing The kit comes in a nice retail package which highlights some of the capacities of the kit: FPV, Omnidrive, AI vision, compass, IR control, APP control, and RGB lights.
