LPC54018 IoT module
5. Power
supplies
The module may be powered either from its on-board USB connector or via the expansion
connector (at pins 51, 53 and 55 of J4). The module incorporates a 5 V to 3.3 V regulator,
which powers the other components on board.
A connection on the J4 connector (pin 100) of the module is used to sense when it is
plugged into a baseboard. The baseboard should connect this signal to its 3.3 V
supply.The module has an FET switch, which is turned off when the baseboard sense is
driven to 3.3 V. It effectively separates the LPC54018 VDD from the VDD of other
components, allowing its current drawn to be measured separately.
6. Compliance
The following information is provided per Article 10.8 of the Radio Equipment Directive
2014/53/EU:
a) Frequency bands in which the equipment operates.
b) The maximum RF power transmitted.
