Understand your gear.
Clear explanations for complex specifications. Explore the materials, electronics and standards behind everyday peripherals.
Materials & manufacturing
How surfaces, plastics and production processes shape a product.
Coatings & surface finishes ↗
A surface finish changes how a peripheral feels, looks, and wears. The finish can come from the mold texture or from a treatment applied after manufacturing.
Materials & manufacturingManufacturing processes ↗
Manufacturing process describes how a part is formed and finished. Injection molding forms plastic parts in a tool; CNC machining removes material from a workpiece.
Materials & manufacturingMaterials & plastic blends ↗
Material names describe families. Performance depends on the actual grade, additives, geometry and manufacturing conditions.
Electronics
Follow a physical input through sensors, firmware and circuits.
Sensors & magnetic sensing ↗
A sensor turns a physical change into an electrical signal. In peripherals, sensors can detect motion, magnetic field, position or sound.
ElectronicsMCU & firmware ↗
The microcontroller runs the firmware that reads inputs, processes them and communicates with the host. Firmware determines how those tasks are scheduled.
ElectronicsPCB & electrical layout ↗
A printed circuit board connects and supports the electronics. Component placement, signal routing and power distribution all influence electrical behavior.
Structure & controls
Understand keyboard layouts, switch matrices and mechanical feel.
Keyboard layout & key mapping ↗
Physical key arrangement, printed legends and the operating system’s language layout are separate parts of the typing experience.
Structure & controlsStructure & switch matrix ↗
The electrical matrix connects rows and columns so the controller can identify pressed switches using fewer pins than a separate wire for every key.
Audio & power
Learn how sound is processed, noise is measured and devices are powered.
DSP & audio processing ↗
Digital signal processing operates on sampled signals. A DSP processor is specialized hardware for running this kind of computation, including audio processing.
Audio & powerPower, charging & USB-C ↗
A USB-C connector identifies a connector system. Supported charging power and data capabilities depend on the devices and cable.
Audio & powerSignal, noise & SNR ↗
Signal-to-noise ratio compares the desired signal with noise and is commonly expressed in decibels. Measurement bandwidth and test conditions matter.
Connectivity
Make sense of polling rates, latency and technical test claims.
Connection speed & polling rate ↗
Link speed describes data capacity. Polling or reporting frequency describes how often input information is requested or sent. Both are distinct from the time a complete action takes.
ConnectivityLatency & wireless timing ↗
Latency is elapsed time between two defined events. A meaningful claim states its start point, end point, connection mode and test method.
ConnectivityReading standards & test claims ↗
A specification defines requirements within a stated scope. A test report records results for identified samples and conditions. Product compatibility and certification claims require matching evidence.
