Description Board Feature R2: Re-layout board, pin location changed. Added native USB support, output four channels data. Need install driver. Only need miniumim four pins for power supply and UART interface. Compatible with our standard M2M interface link here, can be plugged on our other development boards. Logic level chip changed from 8 channels to only TXD/RXD Documentation here. Board Features R1: Lead out all the function pins On board 5V to Vbat 2A DC/DC regulator On board net led, manual boot key Nano sim card slot (smallest phone type) Three-in-one antenna connector, default solder IPX U.fl connectors Back side ED-BTB board to board connector: Includes pin: boot / DTR (PSM wake up) / SIM TXD/RXD / 5V / 3V3 and GND Tested can be well controlled by all of board platform board via uart interface For this series details, please check this page. Documentation here. SIM7080G Features: Global CAT-M and NBIOT bands, design for low latency, low throughput data communication applications Low power PSM mode can extend battery life to 10 years Rich interface UART, GPIO, PCM, SPI, I2C etc Compact size, similar to SIM868 GNSS location tracking
