Figure 1: TB1 Terminal Block Connector
PWR_S EL J umper
The PWR_SEL jumper selects the source of power input to the module, or provides+5VDC to
J1 for use by external circuits. The module takes voltage input from the 2-position on-board
voltage regulator or from the 40-pin MCU connector (J1). Power input at the terminal block
must be DC voltage between +7VDC and +16VDC. Power input on the MCU connector
must
be
regulated voltage between +4.75VDC and +5.25VDC. The MCU_PORT connector power
input allows use of batteries, or other alternate sources, to power the module.
CAUTION:
Module damage may occur if the MCU_PORT power input pins (J1-
1, J1-3) are over-driven.
The PWR_SEL option jumper provides 3 possible configurations; source power from the PWR
connector, source power from J1, or source power from PWR and supply power to J1. The
figure below shows the settings for each configuration.

Module powered from external +6VDC - +16VDC connected to
TB1 Terminal Block. Module provides +5VDC output at pin J1
for use by external circuits.
NOTE:
Power output from the module is limited by the 250 mA maximum out-
put of the on-board voltage regulator.
NOTE:
External circuit connected to J1 should limit current flow to less than
50 mA to prevent current-limiting the power supply (VR1).
