MappyDot+ is a smart ranging sensor which provides system designers with the ability to measure accurate distances on drones and robotic platforms for collision avoidance, area mapping, distance measurement, gesture recognition and motion sensing. The MappyDot Plus uses the VL53L1x laser time-of-flight ranging sensor from STMicroelectronics, which is a 940nm Class 1 (eye-safe; IEC 6082501:2014) laser sensor, in conjunction with an on-board controller to provide a huge range of features. MappyDot Pluses can be used to prevent your drone from colliding with objects or optimise its landing, make star trek like door sensors to open doors automatically or even create unique musical instruments.
Please Note: New firmware features are constantly being developed. For a full list of these features please visit the firmware repository. The boards will ship with the latest release firmware version available on the Github repository.
The MappyDot Plus can also be chained with other SensorDots boards on the same bus (such as the MappyDot).
Also note that the MST pin needs to be shorted to ground or the MST solder pads on the board need to be shorted, on the first device in the chain, or if you are using them standalone. For more information visit the getting started page.
Be sure to remove the plastic tape cover on the sensor before use. The plastic tape isn't calibrated for and will interfere with the readings.
Each MappyDot Plus can provide distance measurements (in mm) up to 4 meters and a non-interpolated rate up to 100Hz, with a programmable field of view (from 15 to 27 degrees) and region of interest selection, without additional optics. Multiple MappyDot Pluses (or other SensorDots boards) can also be chained together easily to gather multi-dimentional data about an area much like radar, without reducing sampling rate due to processing overheads. They are also calibrated out-of-the-box to within ±1mm and can be easily re-calibrated if integrated into a commercial enclosure (with a glass cover). The MappyDot Plus also performs low pass filtering on the motion data that arrives from the sensor, to provide you with the clearest picture of the environment around it. While distance measurement is the name of the game, the MappyDot Plus also offers the following features:
MappyDot Plus footprint scale compared to an Australian $1 coin ($1AUD is the same size as a US Quarter).
While the MappyDot Plus provides a nice, easy to use footprint for developers with many features, it also makes it easy for you to develop for. Upon first power up, the MappyDot Plus allows users to obtain an accurate, up to date position with two lines of Arduino code at any time:
It's really that simple. No special libraries to load, just read a value. The distance measurement leg work is done entirely by the module. Leave all the extra CPU cycles and code writing to the important things.
Please note the MST pin is grounded on the first device in the chain. This is the "master" MappyDot Plus for addressing purposes.
Each MappyDot Plus also offers the following user selectable distance measurement modes, in single or continuous modes (through additional I2C commands):
However, if your application requires something more complicated, more lower level I2C commands are available, or you can always tweak and update the open-source firmware as you please via the, I2C bootloader, even after soldering or mounting the modules.
The SensorDots development board is a breakout board for use with the MappyDot Plus. It gives you the option to either connect 2.54mm (0.1") headers to the MappyDot Pluses for easy removal, or to solder the MappyDot Plus directly to the board. It brings out the ISP programming headers and has a reset button, master select jumper, optional I2C resistors and mounting holes for development use.
The SensorDots mounting board provides two 3.6mm mounting holes that give you the flexibility to place the boards in many arrangements for the best possible accuracy. It is available for sale on the SensorDots store here.
The MappyDot Pluses are assembled in Australia with our own in house reflow capability using a lead-free solder process. The components, boards, solder and our process meet current RoHS compliance requirements. Boards are being made based on demand, so if you miss out on current stock, there will be more on the way very soon. Add to your wishlist if you want to be notified when there's more stock.
There are two options for shipping, one is tracked parcel post and the other is standard letter post without tracking (the MappyDot Plus ships in a rigid 16mm mailer box). If you are ordering 6 or more MappyDot Pluses, the item will be upgraded with tracking in a larger box for no extra cost to the standard shipping option.
If you would like something shipped urgently please contact us before ordering and we can arrange an express option.
While every effort has been made to get the best tracked shipping price for most countries around the world, we may have missed a few (you will see a "Tracked Everywhere Rate" for countries not covered under a custom shipping rate). If you contact us before ordering, we might be able to work out a cheaper tracked shipping rate for your country.
If you find something not right upon receipt of your order, please contact us straight away. We will do our best to help you out or work out a solution for you.

Please note, there is currently uncertain delays on all global mail shipments. Please consider this and check with your local country's postal information before ordering.
Also note that untracked international shipping is not available as Australia Post is not accepting this option (within Australia is fine). Tracked options are still available. We will monitor the situation carefully and update when this changes.
