LattePanda MU Carrier Board Design Challenge

DFRobot and NextPCB are currently running a PCB design contest offering free PCB manufacturing and prizes worth up to $800 to people designing and submitting a carrier board design for the LattePanda Mu x86 Compute Module. As a reminder, the LattePanda Mu Compute Module is an x86 system-on-module initially launched with the Intel Processor N100 Alder Lake-N CPU, and later offered with a more powerful Core i3-N305 octa-core processor.  It comes with up to 16GB LPDDR5-4800, 64GB eMMC 5.1 flash, and exposes I/Os through a 260-pin SO-DIMM connector. Arnon reviewed the LattePanda Mu (N100) with Windows 11 and Ubuntu 24.04 using the two reference carrier boards from DFRobot. But now, the company wants to encourage the development of more carrier boards for the LattePanda Mu, hence the PCB design contest. So what can you win exactly? Winners selected by a panel of judges from DFRobot and NextPCB will be offered […]

Revopoint Trackit – A high-end optical tracking 3D scanner with marker-free scanning (Sponsored)

Revopoint Trackit optical tracking 3D scanner

Revopoint Trackit is a high-end optical 3D scanner that achieves accurate object tracking for small to large workpieces without needing markers on the object’s surface. This significantly increases scanning efficiency over conventional marker-based 3D scanning systems. The 3D scanner features an optical tracking system ensuring smooth scanning despite complex shapes, angle changes, or position shifts, maintaining stable data acquisition. The scanner offers two scanning modes with a 30-line cross blue laser mode for quick scans and a single-line blue laser mode for capturing narrow, hard-to-reach areas. Both laser modes can deal with dark and shiny surfaces without the need to first apply scanning spray, making it great for capturing delicate workpieces like circuit boards. Other highlights include a wide operating range suitable for small to large pieces (think coins to cars), auto gimbal calibration, and the ability to operate the device as a standalone handheld scanner (with markers). Revopoint Trackit […]

AWG to mm² Conversion Explained: Wire Sizing for Safety and Performance (Sponsored)

AWG Conversion Calculator

It is of fundamental importance across a broad range of electrical projects to ensure the right wire size is chosen for the given application. Accordingly, then, there are few more critically needed skills among electricians and engineers than knowing how to convert from AWG to mm2. Before we go any further, let’s quickly set out these two units of measurement: “AWG”, of course, refers to American Wire Gauge – a standardised wire gauge system that goes back to the mid-19th century. As its name indicates, AWG is predominantly used in North America. In Europe and elsewhere in the world, however, millimetres squared, or “mm2”, see widespread use for directly measuring a cable’s cross-sectional area, or CSA. In some contexts, then, you might see AWG being used, while in others, references to wire size may be in mm2. Being able to quickly convert between these two systems will help ensure both […]

Check out this 24-layer HDI PCB made with PCBWay’s high-layer, high-order interposer PCB manufacturing services (Sponsored)

24 layer HDI interposer PCB

Connections between chips have become increasingly complex, and applications with higher frequency and speed requirements may not make use of traditional PCB technology. That’s where the interposer PCB, a new type of PCB comes into play. PCBWay has the capability to manufacture high-layer, high-order PCBs, and even successfully developed a 24-layer, 6-order arbitrary interconnection HDI PCB. The interposer PCB is a highly precise, high-density interconnect (HDI) PCB that allows for a higher wiring density per unit area compared to traditional PCBs. HDI PCBs are characterized by features such as micro vias, finer lines and spaces, higher connection pad density, and the use of blind and buried vias. These features enable the miniaturization of electronic devices by allowing more functionality to be packed into a smaller space. The design characteristics of this PCB include inner layers connected to the outer layers through laser microvias and dense routing, resulting in a multi-structure […]
