EXP32 Prototype Board
The EXP32 Prototype Board is a versatile plugin module for integration of custom circuits with the EFM32.The VMCU power domain is tracked by the Advanced Energy Monitor (AEM), which gives detailed informationabout the current consumption.
Features:• Ready-to-use prototyping area for hole-mount, TSSOP, SO, SOT23-6, SOT23 and 0805 SMD components.• VMCU power domain tracked by the Advanced Energy Monitor (AEM).• 3.3V and 5V power domains available.• All EFM32 IO lines directly accessible through pin headers.• User LEDS ready for use.• LEDS indicating power.

1 Usage
1.1 Placement
This board is intended for use with the EFM32 Gecko Development Kit.
1.2 Prototyping Area
The prototype area supports hole-mounted devices as well as TSSOP, SO, SOT23-x, SOT23 and 0805SMD components. For some of the IC footprints there is a dedicated footprint for decoupling capacitors.Please see schematic for details.
1.3 Voltages
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 supplyvoltages, there is a corresponding LED indicating if the power is present. Either of the voltages may beused to power custom circuitry, but verify not to connect different power-domains directly.
NoteMake sure not to connect circuitry powered by different supply voltages without proper leveltranslation! E.g. do not directly connect circuits powered by 3.3V to the EFM32.
1.4 User LEDs
4 user LEDs with corresponding resistors are available on the protoboard. They may easily be solderedto other circuitry. See schematic for details.
1.5 Pin Headers
The proto board features 10 20-pin headers. Pin 1 and 19 are connected to GND, whereas 2 and 20 maybe 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, providedthat the signals are available from the MCU-board. Also, several peripherals on the Kit mainboard areavailable. Please see the schematic of the respective boards for detailed information.
NoteIn order for a signal from a EFM32 port to be available on the protoboard, the signal mustbe routed out from the EFM32 board.
