Companion development boards for easy prototyping and deployment.

Notecarriers are available in several form-factors to facilitate rapid prototyping. Depending upon the variant, a Notecarrier may be designed with direct host integration, size optimization, integrated cellular/Wi-Fi and GNSS antennas, or even to be soldered directly into a solution for low-volume production.

Functional Description

Notecarriers are designed to bridge the gap between prototype and production for the Notecard. The Notecard is designed to be socketed directly onto the circuit board using an edge connector socket, along with a customer's MCU, sensors, and controls. While such a model provides a highly modular configuration for the final product, it can make prototyping unnecessarily difficult.

Notecarriers offer breakout connections for the Notecard, as well as circuitry to provide power management, protection and signal amplification.

Features

  • Simple. Provides breadboard compatible pins or solderable mask for direct connections.
  • Compatible. Level shifters ensure compatibility with 3.3V or 5V equipment.
  • Convenient. Powered by a micro-USB connector (requires 2A supply).
  • GPS Ready. Models are either active GPS compatible, or feature a built-in antenna to enable GNSS connectivity.

Compatible Notecards

Due to differences in the physical size of Notecards, certain Notecarriers are only compatible with certain Notecards. The Notecarrier A is compatible with:

  • NOTE-NBGL-500
  • NOTE-WBNA-500
  • NOTE-NBNA-500
  • NOTE-WBEX-500
  • NOTE-WIFI
  • NOTE-ESP
  • NOTE-LORA

Package Configuration

  • Center of Mounting Holes: 59mm x 66mm

Power Information

All Notecarriers can be powered by connecting directly to the Micro-USB port. However, most installations will not have USB power available, so several alternate power options are provided by the various Notecarrier models:

  • attaching a LiPo battery.

    The LiPo battery must be a single-cell 3.7V battery with a 2-pin JST PH connector.

  • attaching a solar cell (must be accompanied by LiPo).

    The solar charging circuit is designed for use with a 4.5-7V solar panel.

  • applying 2.5-5.5VDC to the V+ pin.

    Commonly provided via DC power supply or non-rechargeable battery.

warning

Typical USB ports may only be capable of supplying 500 mA of current, which might not be enough to power Notecard during a cellular connection to a GSM network (which can spike to 2A). In this situation, you're advised to supplement power to your Notecarrier with an external source (e.g. a LiPo battery).

GPS (GNSS) Antenna Requirements

All Notecarrier models are designed to support active GPS, and several Notecarrier models provide built-in antennas ready to be connected to a Cellular Notecard using the included U.FL cables.

Active GPS Onboard Antenna

The Notecarrier A models feature built-in, active GPS antennas and are designed with a sufficient buffer to isolate the antenna and minimize interference with the other electronics. Notecarrier A models do NOT support external GPS antennas.

ENIN>1.1v will power on the module, used for main product ON/OFF and for when product is being shipped to ensure that there is no communications attempted. If USB is active as power source, this pin is ignored, else it is required to be tied high or low.
RSTIN>0.8v pulse will cause hard-reset of the module. This pin is internally pulled low, so NC is acceptable.
