5. Locate the µSD card socket, on the Raspberry Pi board, directly behind the white flat
cable. The flat cable has a large ferrite toroid around it. It is not a problem if the toroid
slides up or down, but never remove the toroid
6. Gently move the cable to have enough room to insert the µSD card in its socket; the
card should be inserted with its contacts facing up (toward the back of the unit)
7. Once the card is installed, check that the flat cable is still firmly connected on both
sides; if not, gently lift the connector’s locks, replace the cable and push the locks back
in position
8. Ensure that the toroid is not directly in contact with the µSD card, to avoid damage to
the card when the cradle is re-installed
9. Gently place the cradle back, aligning the mounting screws on the sides; pay attention
not to damage the boards, connectors, and internal cables
10. Screw the two lock nuts.
Terminal block
The Strato Pi Mini Touch Display has a 2-way terminal block, used for the input voltage
connection.
The maximum conductor cross section is 2.08 mm2(14 AWG). Recommended stripping
length is 6 mm. Screw thread is M3. Never exceed 0.5 Nm torque when tightening the
screws. The label attached directly below the terminal block shows where to connect the
positive and negative terminals of the power supply cord.
The Strato Pi Base Touch Display and Strato Pi UPS Touch Display versions have a 9
positions terminal block, used for power, battery, and serial connections.
The maximum conductor cross section is 1.5 mm2(16 AWG), or 0.5 mm2when using
ferrules (highly recommended). Recommended stripping length is 5 mm. Screw thread is
M2. Never exceed 0.25 Nm torque when tightening the screws.
Refer to the appropriate Strato Pi board user guide for detailed connection instructions.
Power supply
Strato Pi Touch Display can be powered with DC voltage only:
✓DC: nominal voltage range 12V to 28.0V.
Respect the correct polarity shown in the schematic diagram (+ -). The power supply
circuit implements reverse polarity protection using an auto resetting fuse and surge
protection up to ±500V/2ohms 1.2/50μs.
A blue on-board LED is lit when power supply is available.
Never connect the Raspberry Pi micro-USB power plug.
