The Hobbywing Multifunction LCD Program Box PRO G3 is an advanced ESC programming device for compatible Hobbywing brushless ESCs. Compared with a simple LED program card, this LCD program box gives users a larger screen, menu-based parameter setup, ESC profile import/export, USB connection for PC-based setup, built-in OTA Bluetooth programming, and battery voltage checking in one compact field-use device.
It can be used as an independent LCD programming box, a USB adapter for Windows PC setup through Hobbywing USB Link software, an OTA Bluetooth module for mobile app adjustment, and a battery voltage checker for supported lithium battery packs. Compatibility depends on the exact ESC model, so always check the ESC manual before use.

Compatible Hobbywing ESC Series
The Multifunction LCD Program Box PRO G3 is designed for compatible Hobbywing ESCs, but support depends on the specific ESC model. The official manual lists Platinum aircraft brushless ESCs, XeRun and EzRun brushless ESCs V2.0 and later, SeaKing Pro brushless boat ESCs, and some QuicRun ESCs. It also covers ESCs supported by the previous LCD G2 program box and OTA Bluetooth module.
| Aircraft ESCs |
Hobbywing Platinum series brushless aircraft ESCs and other compatible ESCs supported by the previous LCD G2 program box / OTA Bluetooth module. |
| Car ESCs |
XeRun and EzRun MAX series V2.0 and later, plus some QuicRun series ESCs depending on model support. |
| Boat ESCs |
SeaKing Pro series brushless boat ESCs and other supported compatible models. |
Important: Do not assume every Hobbywing ESC is compatible. For FlyFun, SkyWalker, QuicRun, XeRun, EzRun, SeaKing, and Platinum models, always check the ESC manual or product requirement before using this program box.
Four Main Ways to Use This Program Box
The Hobbywing Multifunction LCD Program Box PRO G3 is more than a basic programming card. It can be used in several different ways depending on your ESC and setup needs.
| LCD Program Box |
Use the built-in LCD screen to display, adjust, save, and share ESC parameters on supported ESCs. |
| USB Link Adapter |
Connect the ESC to a Windows PC using the Type-C USB interface and Hobbywing USB Link software for parameter setup and firmware update. |
| OTA Bluetooth Module |
Use the HW Link V2 mobile app on iOS or Android to adjust ESC parameters, upgrade firmware, and read data when supported. |
| Battery Voltage Checker |
Connect the battery balance plug to check total pack voltage and individual cell voltage for supported 2–8S lithium batteries. |
LCD Menu Functions
The LCD menu makes it easier to work with supported ESC settings directly from the program box. Available menus include parameter settings, data record, mode setting, and system settings. The exact options depend on the connected ESC model and firmware support.
-
Parameter settings: view and set supported ESC parameters.
-
Data record: view recorded ESC data such as maximum ESC temperature, maximum motor temperature, minimum battery voltage, and maximum motor RPM when the ESC supports data logging.
-
Mode setting: switch ESC profiles on supported multi-mode ESCs and manage saved setup files.
-
Import / add setup files: save ESC settings, import setup files, copy profiles, rename files, delete files, and share settings between supported ESCs of the same model.
-
System settings: adjust language, screen brightness, sound, device information, and reset options.
OTA Bluetooth and Mobile App Setup
The built-in OTA Bluetooth module allows the program box to work with the Hobbywing HW Link V2 mobile app. Through the app, users can adjust ESC parameters, update firmware, and read data on supported ESCs. This OTA function works with both iOS and Android devices.
The factory Bluetooth name and password may be shown in the official manual or app connection process. Always follow the official Hobbywing connection steps when pairing the program box with your phone.
Windows USB Link Firmware Update
The Type-C USB interface allows the program box to connect to a Windows PC. With Hobbywing USB Link software, compatible ESCs can be connected through the program box for firmware updates and parameter setup. The USB Link computer software is intended for PC users only.
The program box firmware itself can also be updated when needed. The official manual lists two update methods: connecting the program box to a computer through USB Link software, or using the HW Link V2 mobile app through Bluetooth.
Battery Voltage Checker Function
The Multifunction LCD Program Box PRO G3 can also work as a battery voltage detector. Connect the battery balance plug to the battery checker port to display the total battery pack voltage and the voltage of each individual cell.
The official measuring range is 2–8S for Li-Polymer, Li-Ion, and Li-Fe batteries, with a measurement accuracy of ±0.1V. When using the battery checker function, do not connect the ESC and USB port at the same time. Dual power connections may damage the program box or connected devices.
Powering the Program Box
The program box uses a DC 5V–12.6V input range. In many setups, the program box may receive power from the ESC programming interface if the connected ESC provides voltage output.
If the ESC programming interface has no voltage output, such as some older OPTO ESCs, an independent battery or UBEC may be required through the 5–12.6V power supply interface. Do not supply external power unless the ESC instructions state that the program box requires external power.
Important Compatibility and Safety Notes
- This product is a programming box and battery checker, not an ESC.
- Compatibility depends on the specific Hobbywing ESC model.
- Use the correct ESC programming interface: independent programming port, shared fan interface, or throttle cable, depending on the ESC model.
- For OPTO ESCs or older ESCs with no voltage output from the programming interface, external power may be required through the 5–12.6V input.
- Do not supply external power unless the ESC manual states that it is required.
- When using the battery checker function, do not connect the ESC and USB port at the same time.
- USB Link computer software is for Windows PC users only.
- OTA Bluetooth app setup works with supported iOS and Android devices.
- Battery checker support is 2–8S Li-Polymer, Li-Ion, and Li-Fe according to the manual.
- Always follow the official Hobbywing manual before connecting, powering, or updating the program box.
