Blues Notecarrier® Datasheet: Notecarrier B v1.0

Companion development boards for easy prototyping and deployment.

warning

While this product is still supported, it is no longer available for purchase from the Blues store. We recommend the Notecarrier XM as an updated alternative.

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 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 B v1.0 is compatible with:

  • Notecard Cellular
  • Notecard Cellular (Legacy)
  • Notecard WiFi
  • Notecard LoRa

Package Configuration

Notecarrier B (Basic) v1.0

Notecarrier B (CARR-B) is designed for building highly customized hardware solutions.

FrontBack
Notecarrier B v1.0 (front)Notecarrier B v1.0 (back)
  • Notecard edge connector socket and mounting screw receptacle .

  • Micro-USB port to power Notecarrier and provide a USB Serial command interface to Notecard.

  • Requires user provided U.FL cellular/Wi-Fi antenna and optional U.FL active GPS antenna.

  • PCB Dimensions: 45mm x 45mm

  • Center of Mounting Holes: 36mm x 36mm (measured from the edge of the PCB to the center of the furthest mounting hole)

Power Information

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

  • 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 Ready

The Notecarrier B, Notecarrier Pi, and Notecarrier R models do not have integrated GPS antennas, but support active GPS by providing circuitry to enable bias voltage to be supplied.

The Notecarrier B v1.0 has a 0Ω resistor connecting the two pins. The resistor can be removed, allowing you to either utilize a passive GPS antenna, or splice into the circuit and provide your own bias voltage.
