Note: See DS52020 User's Guide for more information about 12V converter.
Note: See DS51978 User's Guide for more information about 3V3 converter.
Three power inputs can be used to
power the whole board:
- USB Device
- 5 Volts of mikroBUS interface
- DC jack connector (6V to 30V)
Resistor R23 lets you convert the
buck-bost converter in a buck
converter to increment the power
performance, only when VIN is
higher than 12 Volts.

The PLC signal transformer (TR100) provides safety isolation from
the L-N connection (AC mains or DC).
If removed, when connecting other devices to the board, like a PC
through the USB or JTAG port, it wil be required to add adequate
external isolation (e.g. USB isolator).
Also, in the case of a DC bus, please respect the board polarity and
connect the positive voltage to L and the ground to N.
