  • Built-in 802.11 b/g/n Wi-Fi and dual mode Bluetooth (classic and BLE)
  • STM32 protocol co-processor
  • Integrated ICM-42627 motion sensor
  • Integrated u-blox M10 GNSS module and antenna
  • Integrated SIM7600A-H or SIM7600E-H 4G LTE CAT4 cellular module
  • Integrated buzzer (PWM or DAC driven)
  • Enclosure dimensions: 60x48x20mm
  • Typical power rating @80Mhz: 20mA (WiFi inactive) / 50mA (WiFi active) / 200mA (LTE+GNSS active)

Physical Interfaces

  • OBD-II Type B (HD-OBD) male connector
  • microUSB port
  • microSD card slot
  • SIM card slot
  • GPIO socket (Molex)

OBD-II Compatibility

Freematics ONE+ plugs into the OBD port usually located under the steering column. To check if your vehicle is OBD-II certified, open your hood and find the sticker that looks like this:

Vehicles using following vehicle protocols are supported.

  • SAE J1939
  • CAN 500Kbps/29bit
  • CAN 250Kbps/29bit
  • CAN 500Kbps/11bit
  • CAN 250Kbps/11bit
  • KWP2000 Fast
  • KWP2000 5Kbps

External I/O

Freematics ONE+ has an external I/O socket. The 4-pin socket contains 2x I/O pins (ESP32's GPIO26 and GPIO34), VCC (controllable by ESP32's GPIO12) and GND, as following.

With a Molex to 2.54 Dupont connector conversion cable, external sensors or controller can be easily connected. On the Dupont connector side, black for GND, red for VCC, white for GPIO34 and green for GPIO26.

 

GNSS

Freematics ONE+ Model H integrates u-blox M10 GNSS module and active ceramic antenna. The module is programmatically configurable while NMEA data stream is decoded by co-processor in real-time and coordinates made available to ESP32.

 

Bluetooth

Freematics ONE+ has built-in dual-mode Bluetooth capability and can work with Freematics Controller App via BLE when datalogger sketch or telelogger sketch uploaded.

 

Cellular Module

SIM7600A-H or SIM7600E-H 4G LTE CAT4 module is integrated for high-speed cellular connectivity.

Data Transfer Speed LTE CAT4: Uplink up to 50Mbps, Downlink up to 150Mbps
HSPA+: Uplink up to 5.76Mbps, Downlink up to 42 Mbps
UMTS: Uplink/Downlink up to 384Kbps
EDGE: Uplink/Downlink up to 236.8Kbps
GPRS: Uplink/Downlink up to 85.6Kbps
Regions Europe, Asia, Australia North America (AT&T Certified)

An external cellular antenna connected via a SMA connector is an option for boosting cellular signal reception by 6dB comparing to default internal cellular antenna.

SIM Card

A microSIM card is needed for using cellular network and is inserted as shown below.

Global SIM cards like Hologram IoT SIM card are supported.

 

MicroSD

Freematics ONE+ has a microSD slot under the side cover which is connected to ESP32 via SPI. Standard Arduino SD library can be used for microSD card access.

 

Buzzer

The internal buzzer is connected to ESP32’s GPIO25 and can be driven by PWM or DAC.

 

Low-Power Mode

Freematics ONE+ enters and leaves low power mode programmatically. In low power mode with all peripherals (GPS, GSM, WIFI) powered off, the power consumption is around 10mA. This prevents car battery from going flat while the main controller is still able to run code and perform low-power tasks like motion detection by MEMS sensor.

Development

The most exciting thing about this product is that you can create your own unique product or solution on top of our massive accomplished work. We have been developing and maintaining a dedicated Arduino library for easy access to all hardware resources and a set of fully functional reference Arduino sketches for this product. So there is no need to start from scratch. As long as you have some basic knowledge about Arduino, you are good to go. Together with our Freematics Arduino Builder which allows configuring, compiling and uploading Arduino sketches in one simple GUI, we intend to bring the best out-of-box experience for non-professional developers. If you are a pro, we recommend PlatformIO IDE as development environment and our reference code is organized as PlatformIO projects as well, though you can still use Arduino IDE or Arduino makefile with ESP-IDF. For more information about development, please refer to the Developers Guide.
