This board is intended for use with the EFM32 Gecko Development Kit.
The prototype area supports hole-mounted devices as well as TSSOP, SO, SOT23-x, SOT23 and 0805
SMD components. For some of the IC footprints there is a dedicated footprint for decoupling capacitors.
Please see schematic for details.
The prototype board has 3 supply voltages: 5V, 3.3V and VMCU. VMCU is used by the EFM32 micro-
controller, and the corresponding current consumption is tracked by the AEM. For each of the supply
voltages, there is a corresponding LED indicating if the power is present. Either of the voltages may be
used to power custom circuitry, but verify not to connect different power-domains directly.
Note
4 user LEDs with corresponding resistors are available on the protoboard. They may easily be soldered
to other circuitry. See schematic for details.
The proto board features 10 20-pin headers. Pin 1 and 19 are connected to GND, whereas 2 and 20 may
be connected to VMCU and 3V3 respectively by inserting 0-ohm resistors. See schematic for details.
When the protoboard is connected to the Kit, all GPIO-lines from the MCU-board are available, provided
that the signals are available from the MCU-board. Also, several pheripherals on the Kit mainboard are
available. Please see the schematic of the respective boards for detailed information.
Note
Make sure not to connect circuitry powered by different supply voltages without proper level
translation! E.g. do not directly connect circuits powered by 3.3V to the EFM32.
In order for a signal from a EFM32 port to be available on the protoboard, the signal must
be routed out from the EFM32 board.
