The 12 V
DC
voltage is used to supply the whole board including the microcontroller and the communication interface transceiver chips. The power supply is included in the kit. The 12 V adapter can be supplied with mains 90÷240 V
AC
; the AC plug is the standard CEE 7/16
Europlug. The PSU output barrel connector (+12 V
DC
) is center positive power supply with
2.1/5.5 mm diameters.
+5 V and +3.3 V power supply sections
A dedicated DC-DC converter is used to generate +5 V
DC
. A linear low dropout regulator is used to generate +3.3 V. The switch S1 is used to turn on and turn off the board. 3 LEDs
(D2, D3 and D4) are connected to 12 V, +5 V and 3.3 V respectively.

UM1650 General handling precautions
Appendix A General handling precautions
The following precautions are recommended when using the SPC56EL70L5DISP, the PSU or the SPC56L-Discovery board:
•
Do not modify or manipulate the board when the DC supply is connected to the board.
• Do not open and tamper the PSU. Use AC plug adaptor if the main socket is not compatible with the PSU.
•
Do not supply the board with a DC source higher than 12 V.
• Any equipment or tool used for any manipulation of the semiconductor devices or board modification should be shielded and connected to ground.
•
The connectors and cables should be plugged and removed when the board is off.
• It is suggested recommended to use antistatic tools.
