PCF8576D. Normally a jumper in JP9 is inserted but if removed there are 5 ohm resistors that can be used for measuring the current consumption. 10mA current will give a 50mV voltage drop over a 5 ohm resistor. Copyright 2012 © Embedded Artists AB... - Page 12 There is a LED that signals that +3.3V is present on the board. There are also two ground pads (TP4, TP5) for simplifying connection the ground cable of measurement devices, for example oscilloscope probes. Copyright 2012 © Embedded Artists AB...
