Radio Frequency Testing

Selling a wireless mouse on Amazon US? You need FCC ID certification — and if your mouse uses Bluetooth, the Bluetooth SIG's BQB (Qualification) is also required when you use the Bluetooth trademark. Unlike keyboards or game controllers, a mouse introduces a unique FCC testing variable: the optical/laser sensor produces high-frequency clock harmonics (typically in 100-500 MHz range) that contribute to the Part 15B unintentional emission profile. A 2.4 GHz wireless dongle (non-Bluetooth) follows §15.247 DTS rules but avoids BQB. This guide covers what certification you need, documents to prepare, and practical cost/timeline factors.

FCC Requirements for Wireless Mice — What You Actually Need

• FCC ID (Part 15C §15.247): For the 2.4 GHz radio link (either proprietary or Bluetooth LE). If using a pre-certified Bluetooth SoC, the mouse can reference the module's FCC ID — dramatically reducing RF testing scope. Conducted power ≤ 1W (30 dBm), 6 dB bandwidth ≥ 500 kHz.
• FCC SDOC (Part 15B): For unintentional emissions from the mouse's optical sensor MCU, scroll wheel encoder, and battery charging circuit. The optical sensor's pixel clock (typically 6-24 MHz for an office mouse, up to 180 MHz for gaming sensors) generates harmonics in the 100-500 MHz range — these must be verified against Class B limits.
• BQB (if Bluetooth): Required if the mouse uses Bluetooth and displays the Bluetooth trademark. Very quick if the Bluetooth chip vendor has a QDID — just needs end-product listing. Without QDID, component qualification is needed first.

What Documents You Need

• Product spec (sensor model, radio chip model, antenna type/gain, battery type)
• Radio module FCC ID grant (if using pre-certified module)
• Bluetooth chip QDID (if Bluetooth mouse)
• Schematic + PCB layout + BOM
• User manual with FCC compliance statement
• Samples: 2-3 mice + USB dongle (if included)

Cost and Timeline Variables

A wireless mouse using a pre-certified Bluetooth module and a chip with existing QDID is the fastest and lowest-cost certification scenario — the mouse only needs radiated spurious verification. Adding BQB component qualification (if chip lacks QDID) significantly increases BQB cost. The optical sensor's emission profile is rarely a problem for office mice but can be a pain point for high-DPI gaming mice — pre-scanning the sensor harmonics can prevent surprises during formal Part 15B testing. wireless mouse FCC certification cost estimation based on your configuration.
