Evaluation Board for Hadronmini R1271C, Lepton3 R3100C and Lepton7 R7100C


The RHML37XEVBX Evaluation Board enables quick evaluation and development with Hadronmini R1271C, Lepton3 R3100C and Lepton7 R7100C. It provides an easy way to communicate with the readers via USB-UART or an arbitrary UART host and provides easy access to the inputs and outputs of the device.
The WRHML37XEVBX evaluation board is basically a “breakout board” that allows easy access to the connections of the Hadronmini R1271C, Lepton3 R3100C and Lepton7 R7100C modules. 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.
