What's in the Box (Pre-production version)

These pages for REFERENCE, skip to the Mechanical assembly guide for actual assembly

The MR-B3RB is a "kit of kits", therefore, components are grouped to sub-pages relating to their sub-kits.

These sub-pages will describe the individual sub-kit. Each page contains a components table which enumerates all the parts that are included in the kit.

The diagrams on the pages contain the pictures of the parts.

The parts are labelled with their corresponding serial numbers, either directly in the diagram or in the heading of the diagram. To understand the possible configurations please refer to the Naming and Versions page.

WITB Cables and Screws

Because this is the pre-production version of the MR-B3RB, some cables and screws are not as clearly separated in the sub-kits as they could be. For clarity we will mention them and their purpose here.

Cables and Screws Components

The wires represented by rows with serial numbers 6 and 7 in the following table are not included in the current (Pre-Production) unit. Refer Errata on Pre-Production unit. In their place, incompatible cables are included and their pictures are shown in the diagrams on this page, for reference purposes.

WITB MR-B3RB-PDB (Pre-production)

What's in the box — MR-B3RB-PDB (Power Distribution Board) components

The PDB board is being revised from the pre-production unit to include power measurement capability. The final production version will look different than what is shown here. An image of the production version is included at the end of this page

MR-B3RB-PDB (Power Distribution Board) Diagrams

Production version of PDB

Below is the production version of the PDB.

PDB includes a digital voltage and current monitoring circuit (Px4 standard INA226AQDGSRQ1)
Different method of connecting PWM signals which avoids mixing up the channels. Servo connects to PDB. Servo and motor control PWM sent to real time controller through a single JST-XH connector (XHDP)
LED lighting connection improved. Instead of a split power+signal cable, now uses STEMMAQT type to the PDB and a separate SPI cable to connect to real time controller. Power is injected from PDB.
3rd 5-pin JST Power connector included
QDEC pinout corrected to be 1:1 (error on pre-production version meant that a reverse cable was needed)
Fuse on board (5A populated, could use 3A depending on application.)

WITB NavQPlus with Camera

What's in the Box — NavQPlus with Camera Components

UPDATING: The final version of this kit will be updated so that the camera mount (item 2.B) is instead open on the bottom, allowing the camera cable and camera to be more easily separated from the mount.

NOTE <TODO> 1) The image shows the incorrect cable for item #26. this is a servo extension cable which is MALE-FEMALE and it is already attached to the B3RB. There is only one of this Male-Female Cable. Note the naming of 600-10006 "" is in fact correct. These cables are used to jumper between the pin headers on the PDB and the MR-CANHUBK344
