ED20 Tracker Board, GSM GPRS GNSS BT3.0 IOT

Description

• Based on our ED20 module, Support GSM GPRS GNSS, advanced MT2503 tracker technology. Original CE CCC certificated. Support custom module label for buck order 20pcs
• ED20 Based on Mediatek MT2503 solution, some introduction info can see here.
• Support power up to track, auto send GNSS (or LBS indoor) data to server by GPRS.
• Speedy GNSS tracking, with our setup and next to window, normally position will be fixed in 30~40 seconds, precision is advertised within 10 meters, antenna is a must have.
• Support LBS location indoor (precision is about within 100 meters by our test)

• Support re-labeling for buck order over 20pcs, lead time is 2-4 days. Similar format, can change model name and vendor name.

Breakout Features:

• Please see attached image.
• Board size 48*39mm
• Support micro USB debugging via CH340E, 5V logic compliant, support maximum grogramming speed.
• USD debugging and programming
• Power solution:
  • 5V USB power directly, work smooth, good usb cable required
  • VIN – On board – MCP2315 DC-DC regulator, support 5-24V via VIN port
  • ! REMOVE 0R to use this,otherwise BURN CH340 USB-TTL IC !
  • VBAT – 4.2V lithium battery support by module, via VBAT pin.
• SPK2 can drive 8ohm speaker, SPK1 and MIC can work with normal microphone or speaker (like normal phone but not loud) in our store.
• VRTC can backup RTC time, when power down can still store RTC time for a while.
• All lead out pins:
  • UART1: TX RX GND, 5V compliant (V~ is CH340E step-down voltage, not use)
  • DBG-UART: TX RX GND, 5V compliant
  • PCM interface
  • GNSS can set to power off by external pin (GNSS_EN to GND)
  • GNSS UART TX RX (jumper to UART2)
  • UART2 TX RX (jumper to GNSS UART)
  • SIM2 interface
  • SD card interface
  • MCU power key drive by mosfet
  • ADC analog read pin
• NANO sim card (smallest card size, you can get a IOT sim card if you use a IOT solution)
• SIM reserved ESD IC SMF05, but NOT placed
