5. ATAB0101A PCB Description
Figure 5-1 on page 9 shows the ATAB0101A PCB used as a platform for the SIGFOX™kits. It works in three different modes
depending on the component mounted on the PCB:
1. Battery powered standalone operating mode for the ATA8520-EK1-E kit:
●Includes the Atmel®ATA8520D SIGFOX device
●Includes the Atmel ATmega328P AVR®microcontroller with 8MHz internal clock and external 32.768kHz
crystal
●Includes the AT30TS75A temperature sensor with TWI
●Includes an ATAES132 crypto device (footprint)
●Includes an SMA antenna connector for an 868MHz external monopole antenna
●Two LEDs:
i. Green LED LD1 to indicate the sensor power
ii. Red LED LD2 connected to port pin PD5 and connector X2/pin8 and X6/pin6 for the user application
●User button SW1 connected to port pin PD6 and to connectors X2/pin4 and X6/pin7
●Supply voltage divider connected to pin ADC0 to measure the battery voltage against the internal 1.1V
reference
●Includes the footprint for the following TWI sensor devices:
i. BMP180 air pressure sensor
ii. HTU20D/SHT20 humidity sensor
2. Operating mode with an additional Xplained mini or Arduino UNO kit for the ATA8520-EK2-E extension board
using an ATmega328P:
●Includes the Atmel ATA8520D SIGFOX device
●Includes the AT30TS75A temperature sensor with TWI
●Includes an ATAES132 crypto device (footprint)
●Includes an SMA antenna connector for an 868MHz external monopole antenna
●Two LEDs:
