2 Technical Data Connectors
The PicoCOM1 is equipped with a
TycoElectronics 5177984-3 (8 pin, 0.8mm)
connector from ‘0.8mm Free Height (FH) Connectors’ series.
Matching connectors are:
5mm stacking height: TycoElectronics 5177983-3
9mm stacking height: TycoElectronics 5-5179009-3
13mm stacking height: TycoElectronics 5-5179010-3

3.1 Counting of the connector pins
The connector plug of PicoCOM1 will be treated as follows.
Pin 1 is marked in Figure 1.1. The row with pin1 contains all
odd-numbered pins (1, 3, 5, 7 etc.), and corresponding to this,
the row without pin 1 contains all even-numbered pins (2, 4, 6,
8 etc.).
3.2 IO-Pin limitations
PicoCOM1 is equipped with 43 pins that can be used as digi-
tal-IO. Most of these pins are multiplexed, so you have to
make sure that these pins are used for one purpose only. For
example, if you intend to use IO0 to IO3 you have to make
sure that the COM2 is disabled.
Additionally there are some IO-Pins which are used internally
and whose primary function can’t be disabled completely.
These pins may carry active signals while the device is boot-
ing, which must be kept in mind when connecting external
hardware. For example even if you don’t intend to use COM3
in your application, Pin43 and Pin44 be configured as serial
line in the bootloader for a short period of time. will send
Pins that could toggle during boot are marked with a * in the
following table.

1) These pins carry internal signals and may toggle during boot.
2) Like 1) theses pins carry internal signals. But this restriction is limited to
hardware revisions ≤1.20 only.
3) If using the CAN interface, these pins are restricted to SPI function.
See PicoCOM1 starterkit documentation for connection exam-
ples.
