PCAN-MicroMod Evaluation Kit
User Manual
The equipped Low-speed CAN transceiver may be
deactivated
later
on by setting a solder bridge on position JP21.

RS-232
The Evaluation Board has a serial port corresponding to the RS-232
standard with the signals TxD, RxD and GND. This port is used for
uploading a firmware to the MicroMod. The connection to the PC is
done with a serial extension cable (1:1). You can find information
about a firmware upload in the user manual for the PCAN-
MicroMod.

Power Supply
The Evaluation Board gets a DC voltage of 9 V from the included
wall supply via connector J11 (upper left). The voltage regulator on
the board provides the necessary supply for the MicroMod (JP31
shortened on position 1-2, default).
The
LED
LD25 indicates that the Evaluation Board is supplied.
At higher input voltages and higher environment temperatures at
the same time (e.g. 12 V, above room temperature) an
alternative
voltage regulator
7805 with heat sink can be installed on position
J19. Optionally the use of an
integrated switch regulator
(e.g.
PT5101, PT78HT205, PT78ST105, each by Texas Instruments) is
possible. For example, this is reasonable in an environment with
raised input voltage (e.g. 24 V). In all cases each JP30 and JP31
must be shortened in position 2-3 (positions 1-2 stay open).
