2.2 EVM Assembly Instructions

This section has step-by-step instructions on how to assemble a circuit configuration from the EVM.

  1. Choose the desired circuit configuration. See Section 2.1 for the location of each circuit configuration.
  2. Gently flex the PCB panel at the score lines to separate the desired circuit configuration from the EVM.
