account the anticipated maximum actual operating temperature. AWG#24 stranded high quality wire is recommended
for the
+VIN
and
GND
power connections, and generally AWG#28 is acceptable for the remaining signals.
Ensure sufficient wire size for the SIM to avoid wire overheating and adequate power handling capability.
Several signals on this connector are directly connected to signals on other connectors, including
+3V3
,
RESET#
,
+VEXT
.
Ensure these connections are appropriate or you may damage your SIM or connected equipment.
JST America
offers a sample service for wire harnesses, and custom wire harness manufacturers such as
TLC Electronics
can assist in small to large volume harness development and production at reasonable cost. Most
SIM535 Development
Kits
include a sample single-ended wire harness for your use in prototyping.
60-PIN BOARD-TO-BOARD EXPANSION CONNECTOR (J7)
While the 16-pin
Power and Communications Connector
is the a common way to connect an external system to the
SIM535, the SIM535 Serial/Power Expansion Connector is one of the most flexible off-module connectors available and
exposes many more signals. Often a simple daughter-card will be attached to the SIM535 using this connector to adapt
the SIM535 to a particular system environment.
The Serial/Power Expansion Connector (if present) is the
FCI 10106813-061112LF
, a 60-position, 0.5mm, gold plated,
hermaphroditic board-to-board SMT connector. This connector is inexpensive, reliable, and widely carried at authorized
distributors, including
Digi-Key
and
Arrow Electronics
.
This connector exposes numerous serial, power, and GPIO signals from the MCU, including the same connections as the
16-pin Power/Communications Connector (J8)
. If desired, this connector can be the only external connection to the
SIM535.
SHIPEngine
v5 can use the UART, SPI, or USB signals on this connector as the main communications mechanism for
communicating with external systems.
The
RX63N/RX631
MCUs have extensive I/O multiplexers allowing one of many different peripheral functions to map to a
given I/O pin: consult the
RX63N/RX631 hardware manuals
for the complete list of options.
Ensure you follow the
recommended mechanical guidelines for custom daughter cards
.
Several signals on this connector are directly connected to signals on other connectors, including
+3V3
,
RESET#
,
+VEXT
.
Ensure that common signal connections are appropriate or you may damage your SIM or connected equipment.
