  • Based on our ED20 module, Support GSM GPRS GNSS, advanced MT2503 tracker technology. 
  • 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)

 Breakout Features:

  • Please see attached image.
  • Board size 48*39mm.
  • Support micro USB debugging via CH340E, 5V logic compliant, support maximum programming 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).
  • 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.
  • Demo video could see here.
  • Board Tracker firmware.
  • Default firmware pre-flashed in tracker version.
  • Code based on standard AT commands.
  • Breakout board send GPS HEX data to server once power up, and server read HTTP socket data and generate HTML by python script.
  • Server Script: Please find this python script in this github page.
  • All board tested before send, when you receive board, you can try with SN-number to see the last record in our factory, for example:HTML address1 google. map:
  • HTML address2 map :  (CN address with map fixed, an issue in China).
  • Support to send by HTTP RESTful coordination data to (need to build your own server, script embedded our API number).
  • SDK can be setup in 5 minutes.


Package includes:

  • Board only – only main breakout board, you can set your own antenna.

Update and TODOs:

Updated server:

  • Server is moving to, IP address is, example tracking link is

Test GPIOs:

  • DTR, RTS, etc all spare pins can support SPI, IIC and GPIOS, examples in wiki page, we will try to implement this.

Updated Board layout:

  • Slightly update board update for better production, nothing special change or update.
