Description This is a integrated NB IOT GNSS module, small integrated size and very low power consumption. BC20 Module Main Features: Compact dual-band NB-IoT wireless communication module from quectel LCC package, ultra low power consumption, ultra high sensitivity Multi-satellite navigation system: GPS/BeiDou/QZSS Support AGPS technology Support rich external interfaces and multiple network service protocol stacks, easy to use Package design compatible with remote communication GSM/GPRS/GNSS modules for easy product upgrades Meet customer requirements for rapid time-to-market by providing reference designs, evaluation boards, and timely technical support Board Features: Lead out all the pins from module. The following pins lead out via logic shifter TXD, RXD, DBG_TXD, DBG_RXD 1PPS RI, RTS, DCD Default logic shifiter output use 3.3V, if you need use 5V, please supply from EXT_5V. Power Supply: Power supply from 5-9V VIN, GND pin PSM mode power consumption down to 3.5-5uA. Lead out on board LDO 3.3V pin: INT_3.3V, default use for 3.3V logic supply. You can also supply 3.3V to module from external or by Li-MnO2/2S battery. EXT_5V for external logic shifter supply pin. The followin pins lead out directly back side left: CTS back side right: USB3.3V, USB_MODE, ADC, USB_DM, USB_DP, TXD_AUX, RXD_AUX back side right via transistor, can be controlled by external MCU: MCU_EINT, MCU_RST, MCU_KEY All in one comptaible antenna, default solder IPEX connector, you can remove it to use SMA or through-pin antenna connector too. Notice: Please double check first if your network operator can support B5 or B8 band, here. Other bands are still on development. Please notice module 1PPS, netlight functions are still on development, so LEDs and lead out pins are NOT working. Please refer to datasheet. Documenation please see on this page.
