A portable radiation detector PCB can describe very different electronic instruments. A Geiger-Müller tube survey meter may need a compact high-voltage bias supply and pulse discriminator; a semiconductor detector may emphasize leakage control and low-noise analog...

A portable endoscope camera PCB can refer to electronics for industrial inspection products or to camera electronics intended for regulated medical devices. The underlying hardware may share miniature CMOS sensors, LED illumination, narrow probe cables and...

A portable EMF meter PCB is unusual because the electronics being manufactured can generate the same kinds of fields the instrument is intended to detect. Switching regulators, MCU clocks, display buses, USB, wireless radios and high-current LED or buzzer loops can...

A portable CO2 monitor PCB has to support accurate gas measurement while operating inside a small battery-powered enclosure that also contains processors, displays, charging circuits and, in many products, wireless radios. Those blocks can create heat, supply...

A portable borescope PCB is rarely a single board. Most inspection cameras divide the electronics between a miniature camera head at the probe tip and a larger control board in the handheld unit, USB adapter or Wi-Fi module. A long flexible cable connects those two...

A Travel Router PCB may support hotel Ethernet, upstream Wi-Fi, repeater or bridge operation, USB tethering and VPN functions, but the exact combination belongs to the customer’s product definition. Those WAN modes change connector count, processor and memory demand,...

A Satellite Messenger PCB is the electronics platform inside an off-grid communicator that uses a supported satellite service for messaging, tracking, location sharing or SOS workflows. The customer’s satellite module/service architecture, GNSS, local wireless...

A Portable Weather Station PCB can serve a handheld weather meter, a field logger or a compact station with external wind, rain or other environmental sensors. The sensor list matters because each measurement has different exposure requirements: temperature and...

A Portable Air Quality Monitor PCB can support particulate-matter, carbon-dioxide, VOC, temperature and humidity sensing, but those measurements do not use one universal sensor principle. The approved PM, CO2 and VOC devices have different airflow, warm-up, power,...

A Personal Locator Beacon PCB belongs to a regulated 406 MHz distress-beacon program. In that context, the PCB factory manufactures to the customer’s approved design and controlled test method; it does not redefine the beacon protocol, registration workflow or...
