EVALUATION BOARD
Introduction
Fig. 5.1: WRHML37XEVBX Evaluation Board for R9100C
The WRHML37XEVBX Evaluation Board enables quick evaluation and development with Lepton
9
R9100C. It
provides an easy way to communicate with the Lepton
9
R9100C via USB-UART or an arbitrary UART host
and provides easy access to the inputs and outputs of the device.
The WRHML37XEVBX evaluation board i
s basically a “breako
ut boar
d” that allows easy a
ccess to the
connections of the Lepton
9
R9100C module. The board is designed to roughly conform to the Raspberry Pi
“HAT” form factor,
meaning it can be plugged directly into the IO port of a Raspberry Pi single board
computer, and be powered by and communicate with the Pi. It can also be used as a USB peripheral to a
desktop computer or connected to an arbitrary host device and power supply.
