DHX91 EVB (= ULE Node)
The DHX91 EVB includes a DHAN Module (a custom version with printed antenna), several push
buttons, LEDs and access to vital IO pins that facilitate simple application emulation. The EVB can
be powered using the AC transformer outputting 5V (supplied with the Kit) or using a CR123A
battery. The EVB is delivered configured for this latter case. See the jumper configuration below for
both cases. It is suggested to initially power up the EVB with a 3V power supply clipped to the
battery holder to get feedback regarding the current drain.
The EVB can function as a standalone demo device (Step 1 below) or as a development tool to be
interfaced via RS232 to a PC (Step 2 below) or via UART to an external controller (Step 3 below).
