NBIOT + GNSS Module BC20, B5 B8 Band

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.
