Installation steps

Please follow the steps below to properly install the heatsink.

  1. Prepare your PICO baseboard, PICO module, Wi-Fi antenna and PICO heatsink kit. Besides you need the following tools: a PH00 screwdriver, a hexagonal 3.0 x 7.5 sleeve screwdriver and a pincer.
  2. Locate three module holes on the baseboard, insert screws into the holes from the rear side. Then insert slowly the module and gently press into the development board to secure it. Place and tighten nuts on top.
