2.6. Power Consumption Measurement Control Switch
The EVB contains a single pole double throw switch. When the switch is in the closed state, USB can be
connected normally; When the USB switch is off, Type-C only supplies power to the EVB without USB
interaction function, and it can be used to measure power consumption of the module.
2.7. Indicators
There are five functional indicators on the EVB:
⚫ PWR: power supply indicator.
⚫ P01: Pin 1 of the module. Indicator for EC200A-XX PWM0 by default.
⚫ P05: Pin 5 of the module. Indicator for NET_MODE.
⚫ SCK1: Detection indicator for SIM1. It is on when SIM1 card is inserted.
⚫ SCK2: Detection indicator for SIM2. It is on when SIM2 card is inserted. It is connected to Pin 128 by
default. EC200A-XX does not have SIM2, which can be ignored.
2.8. ADC
ADC0_IN/ADC1_IN are led as test points by default. The input voltage cannot exceed the VBAT voltage.
The ADC0 input voltage is one-fourth of the ADC0_IN input voltage. The ADC1 input voltage is one-fourth
of the ADC1_IN input voltage.
