POWER SUPPLY CIRCUIT:

EM-32G210F128-H is typically power supplied by Li-ion battery but battery connector allows 3.7-5 VDC.

The board can also be power supplied from extension CON2 pin 10 (VIN – 3.8-6VDC) and pin 11 (GND) and from DBG connector(pin19 – 3.8-6VDC).

The programmed board power consumption is about 7 mA with all peripherals enabled.

RESET CIRCUIT:EM-32G210F128-H reset circuit includes R9 (330Ω), CON2 - pin 2, DBG

connector pin 15, EFM32G210F128 pin 9 (#RESET) and RESET button.

CLOCK CIRCUIT:

Quartz crystal Q1 32.768 kHz is connected to EFM32G210F128 pin 7 (LFXTAL_P/US1_CLK/PB7) and pin 8 (LFXTAL_N/US1_CS/PB8).

Quartz crystal Q2 32MHz is connected to EFM32G210F128 pin 12 (HFXTAL_P/LEU0_TX/PB13) and pin 13 (HFXTAL_N/LEU0_RX/PB14).

JUMPER DESCRIPTION:

BUT_EThis jumper enables the user button – BUT.Default state is closed.

INPUT/OUTPUT:

Status led (green), with name LED, connected to EFM32G210F128 pin 1 (TIM0_CC0/I2C0_SDA/PA0).

User button with name BUT connected, via BUT_E, to EFM32G210F128 pin 2 (TIM0_CC1/1/I2C0_SCL/CMU_CLK1/PA1).

User button with name RST connected to EFM32G210F128 pin 9 (#RESET).
