Board-to-Board (BTB) connector selection is governed by five parameters: pitch (0.4 mm to 2.54 mm), stack height (1.5 mm to 20 mm), current rating per contact (0.3 A to 8 A), data rate support (up to 28 Gbps for high-speed…
Overview The MT3608 is a compact, high-efficiency PWM step-up DC-DC boost converter in a SOT-23-6 package. It accepts input voltages from 2 V to 24 V and regulates output up to 28 V at switch currents up to 2 A.…
Key Takeaways FL (Hirose) and IPEX MHF connectors are both 50-ohm micro-coaxial board-level RF connectors used to connect PCB-mounted radios to external antennas. FL and MHF1 are mechanically compatible and interchangeable; MHF4 and MHF5 are smaller, higher-frequency variants that are…
Membrane switches are thin, flexible human-machine interface (HMI) assemblies. Engineers deploy them in medical equipment, industrial control panels, handheld instruments, and point-of-sale terminals worldwide. The central design decision concerns whether the switch delivers tactile feedback—a perceptible snap confirming actuation—or non-tactile…
Choosing the wrong electrical engineering software can cost your team weeks of rework — and sometimes an entire PCB spin. Whether you’re a startup engineer evaluating KiCad for the first time, a PCB designer deciding between Altium Designer and Cadence…
Key Takeaways Silicon Revision Upgrade: The ESP32-WROOM-32E is built on ECO V3 silicon, delivering hardware-level fixes for critical security flaws and power management bugs that persist in the ESP32-WROOM-32D’s ECO V1 silicon. Enhanced Security Posture: The 32E resolves the ‘Fault…
Behind the control panel on a hospital ventilator, the keypad on a CNC lathe, and the touchpad on your microwave sits the same unassuming component: the membrane switch. It is a low-profile, pressure-actuated switch that integrates graphic legend, user-interface logic,…
LED 1210 and SMD 1210 components use a standardized package measuring 3.2 mm × 2.5 mm. The EIA imperial code represents the body size in hundredths of an inch: 0.12″ × 0.10″, while the metric designation is 3225. IEC 60115-8,…
What You Need to Know PCB board viewers (Gerber viewers) let engineers and manufacturers visually inspect fabrication files before production, catching costly errors early. Modern tools support Gerber RS-274X/X2, ODB++, IPC-2581, and Excellon drill formats — the core standards used…
Miss one tolerance call on your gasket groove, and your prototype will come back wrong. Specify the wrong aluminium alloy, and your front panel warps under heat or corrodes in the field. Skip the anodising layer calculation, and connectors simply will not…
