4.1.5.1 Fan

This evaluation module includes components that can get hot to the touch, because this EVM is not enclosed to allow probing of circuit nodes, a small fan capable of between 200 LFM and 400 LFM is required to reduce component surface temperatures to prevent user injury. The EVM should not be left unattended while powered or probed while the fan is not running.
