01. NEQTO Bridge Module

Overview

The NEQTO Engine installed on the NEQTO Bridge Module makes it easy to connect to NEQTO Console and the customer's cloud environment. It also allows customers to easily control sensors and devices via physical interfaces.

It has the following features:

  • Wi-Fi, LTE Cat.1, LTE Cat.M1, LTE Cat.NB1(*1), LAN(*2) communications are supported.
    *1: Please contact us if you would like Cat.NB1.
    *2: Please refer to LAN Module Installation.
  • Because each module is designed under a common interface, it is easy to replace modules.
  • Built-in Antenna (If you would like an external antenna, please contact us.)
  • 3.0 V - 5.25 V operating voltage range.
  • Low-power functionality
  • Photocouplers and MOS relays can transmit signals while electrically isolated from the customer's circuit, and can drive a 12 V interface. (24V interface is available for MOS relay)

  • All unused pins except NRST and USER_SW can be left open (not connected).
  • VDD_RTC(1.55 V to 3.6 V) can be left open when RTC power is not supplied from a battery independent of the system power supply (VDD_BATT).
  • Input terminals other than NRST (reset input), ANALOG1 (ADC input 1), ANALOG2 (ADC input 2) and NODE1_PhotoMOS_IN (photocoupler input) have a 5 V tolerant function. However, note that the digital output of the NEQTO Bridge Module is a 3.3 V output. (Excluding NODE1_RELAY_OUT (relay output))
  • For digital output voltage, refer to Interface Specifications.
  • Note 1) When using PWM output with GPIO11, the pulse cycle that can be specified is up to 100 ms.
  • Note 2) Since the PWM function of GPIO15 and GPIO16 uses the same signal generation source, two ports can generate phase-synchronized pulses. You can specify the pulse period and pulse width for each of the GPIO15 and GPIO16 ports by the neqto.js GPIO object, but the pulse period that is last set out of these two port settings will be applied. Although different pulse periods are not possible, the pulse width can be set for each port.
  • Note 3) GPIO11 can be set only GPIO operation mode 5(OUT/PUSH-PULL) or 9(OUT/PWM). The contact configuration is "1a (SPDT-NO)". For the connection of the relay, refer to the block diagram of each module.
  • Note 4) GPIO13 can be set only GPIO operation mode 2(IN). In addition, the signal polarity obtained from GPIO is opposite to that of the photo coupler input. For the connection of the photo coupler, refer to the block diagram of each module.
  • Note 5) Some NEQTO Bridge Module have restrictions on the wakeup function of GPIO13.
    Please check the NEQTO Bridge Module you are using.

About User Console Mode

The User Console Mode provides a command console interface using the UART interface.
It is available for inputting various settings commands and displaying real-time logs.

When the power is turned on while the USER_SW signal is High, the User Console mode is activated.

Note that it is required to configure the NEQTO Bridge Module communication settings from the User Console mode. Therefore, it will be necessary to prepare a method to control the logic of USER_SW.



About Serial ID

The NEQTO Bridge Module is assigned a 16-digit serial ID.
This serial ID is a unique number for each NEQTO Bridge Module.

The upper 8 digits of the serial ID indicates the type of the NEQTO Bridge Module and is a unique number for each type.
The last 8 digits are the serial number assigned at the time of manufacture.

About QR Code

A QR code label is attached to the NEQTO Bridge Module.
The location of the QR code label varies depending on the NEQTO Bridge Module type.

      


Shown on the QR code label are the QR code and the serial ID (16 digits).
The QR code contains the ',' separated serial ID (16 digits) and the product key (16 alphanumeric characters).

 QR code data (serial ID,product key)
 0123456789012345,ABCDEFGHJK123456

The serial ID and product key are required to register the device on the NEQTO Console.
