Are you tired of carrying around a bulky remote every time you want to ride your electric skateboard? Then this Android Bluetooth Controller is for you! Specifically designed as a direct replacement for the HobbyKing GT2B, this RC receiver requires very little setup, and can even tell you your remaining battery life via the built-in voltmeter! No more guessing how much juice you have! This product is a kit, which means you will need to assemble it. Minimal tools are required (a soldering iron, solder, and a heat gun/lighter). Documentation for assembly will be provided. Here are the specs:
– Android compatible app
– Powerful and jam-resistant Bluetooth 2.1 (not Low Energy variant)
– Has all of the functionality of the HobbyKing GT2B
– Modes: Car/Boat and Electric Skateboard
– Signal Type: PPM (Majority of Servos and ESCs)
– Sensitivity: 1000 degrees
– Input Voltage: 4.5~6.5 VDC
– Voltmeter Accuracy: 1%
– Max Voltage Measurement: 55 volts (12S LiPo)
– Failsafe: Slowly turns off the motor (coasting)
– Range: 30 feet
– Dimensions: 46 x 40 x 11mm
The Android application is constantly being updated and worked upon, and new features are constantly being added. It is compatible with Android 4.0 and up, and the latest version will be available for for download after your purchase. All subsequent updates will be emailed to you as well.
Once payment is confirmed via PayPal, you will receive the necessary files to solder the controller together. These files will include a full schematic, a board layout file (with part labels), and a parts list. All of the components are through-hole, and the microcontroller and Bluetooth radio come pre-flashed with the appropiate firmware.
Installation and Setup
The installation and setup of this controller has been made as intuitive as possible, and is identical to the setup process of a standard RC controller, like the HobbyKing GT2B. Simply plug the three-color wire of the ESC into the ESC port of the controller. The label next to the ports has a symbol like this one: “~ + -“, which indicates the order of the signal, positive, and negative wires. Repeat the process for any servos and accessories you may want to control.
This controller is compatible with almost all ESCs out of the box! No programming required! In case your ESC does not recognize the signal, you will need to consult your ESC’s manual in order to set throttle range, and/or reset to factory conditions.
Once you have the controller connected to your ESC, you will need to solder/connect the included male JST connector to your battery pack, then plug the JST connector to the receiver. Here is a fairly standard connection diagram for an electric skateboard/RC car.
In order to pair your smartphone with the controller, first apply power to the ESC, and consequently the receiver. You will then need to open the Android app, press the “Pair a Board” button, make your device visible to others, then click on the “EBOARD” device down below. The password for the receiver is either 1234 or 0000.
Payment and Shipping
PayPal is the only accepted method of payment. The controllers are individually tested for functionality before being shipped. Any conflicts will be resolved via PayPal, but your satisfaction is my priority. If you have any questions or concerns about this item, please email [email protected]!
By purchasing this product, or using any services on this website, you automatically agree to our Terms and Conditions policy, as outlined here. I am not responsible for incorrect assembly of the controller.
Here is a short video about how the controller is actually assembled from start to finish. A lot of effort was made to ensure the quality and safety of the controllers, and additional testing was done when the camera was not recording.
And here is a short video of me riding an electric longboard with a prototype controller. A lot more features were added since then.
Here is an update I did a while back on the controller project. It covers all of the prototypes of the controller, as well as the development of the app. Since then, I have made the PCB and layout more professional, and worked towards making this an actual product.
And here is a bonus video. I hacked a Wii Nunchuck controller to be compatible with my receiver, and you can do this yourself as well!
