The ultimate starter kit for mmWave sensing. Includes the HLK-LD2410B Bluetooth Radar Module AND a dedicated USB Breakout Board. Plug directly into your PC for instant configuration and testing.
The "Zero-Solder" Way to Master mmWave Radar. The biggest challenge with modern compact sensors is the wiring. The HLK-LD2410B is powerful, but its tiny 1.27mm pin pitch makes it a nightmare to connect with standard jumper wires. This Hi-Link HLK-LD2410B Development Kit solves that frustration instantly. It combines the powerful Bluetooth-enabled Radar Module with a dedicated USB Breakout Board. No soldering, no loose wires—just plug it into your computer's USB port, launch the software, and start tuning your presence detection in seconds.
Quality Advantage: Developer-Ready Out of the Box. This isn't just a sensor; it's a complete testing rig. The included USB test board routes the tiny radar pins to a standard USB interface (typically Type-C or Micro-USB) and provides stable power regulation. This allows you to visualise the radar data in real-time on your PC using the official Hi-Link debugging tool. Once you have configured the perfect sensitivity settings for your room, you can unplug the module and deploy it in your final project, or leave it connected as a permanent USB sensor for a Raspberry Pi or Home Assistant server.
Key Applications & Projects
Rapid Prototyping: tune sensitivity parameters in real-time without recompiling code.
USB Presence Dongle: Plug it into a smart home server (like a Raspberry Pi running Home Assistant) to add presence detection to the server room.
Portable Site Survey: Power it with a power bank and use the phone app to test radar placement in different rooms before permanent installation.
Classroom/Education: ideal for teaching students about radar technology without the risk of wiring errors.
Specifications
Module: Hi-Link HLK-LD2410B.
Adapter Chip: CH340 / CP2102 (Driver installation may be required).
Input Interface: USB (Type-C).
Radar Frequency: 24 GHz ISM.
Detection Range: 0.75m - 6m (Adjustable).
Bluetooth: BLE 4.2 (Built-in).
Output: Serial Data (to USB) + Bluetooth.
Project Evolution
Prerequisite: None. This is the absolute easiest way to start.
The Upgrade: This kit bridges the gap between "Hardware Hacking" and "Software Development." You can focus entirely on the logic and automation rules (Software) without worrying about voltage levels and loose connections (Hardware).
Effort Level: Beginner. True Plug-and-Play.
Virtual Technician & Wiring Guide
⚠️ Driver Installation: If your PC does not recognise the board, you likely need to install the CH340 or CP2102 drivers. Check Device Manager > Ports (COM & LPT).
Orientation: The radar module usually plugs into the test board in only one direction. Do not force it.
Heat Management: The radar chip generates heat during operation. The PCB acts as a heatsink, so it may feel warm to the touch. This is normal.
Bluetooth Conflict: You can configure the module via the PC Software (USB) OR the Phone App (Bluetooth), but try to avoid doing both simultaneously to prevent setting conflicts.
Accessories & Compatibility
Included in the Box:
1x HLK-LD2410B 24GHz mmWave Radar Module (Bluetooth Version).
1x USB Test Board (USB-to-Serial Adapter specialized for LD2410).
Hardware Compatibility:
PC/Laptop: Windows (Required for HLKRadarTool PC software).
Raspberry Pi / Linux: Recognized as a serial device (/dev/ttyUSB0) for direct integration.
Power Bank: Can be powered directly via the USB port for portable testing.
Software Support:
HLKRadarTool (PC): Advanced visualisation of "Moving" vs "Static" energy gates.
HLKRadarTool (App): Configure wirelessly via Bluetooth (Android/iOS).
Home Assistant: Plug-and-play via USB using the standard ESPHome ld2410 component.

We are into electronics & mechanical projects in this connection we had contacted probots & we visited them , To our pleasant surprise , their presentation with us was friendly wrapped with professional support , which helped us to choose better , this interaction was patient & excellent .with all confidence i shall promote them to my known sources looking for components . Pls maintain this attitude towards customer this shall take your organization to heights
Great place to get all electronic components and accessories for electronic products.
I had ordered something, will write review after the order process is complete.
Ordered a couple of times, Bad Experience. They charge premium delivery fee but delivery will not happen on time(every time). And the resopnce after sales on the issues such as delivery is slow and not friendly. If you can take the delivery at your own risk, and liesure you can order.
I would like to share a suggestion based on my recent experience. I am also running a private limited company and understand how important customer relationships are. One key area that needs attention is training employees on how to deal with customers professionally and respectfully. No business starts with bulk orders—every relationship begins small and grows with trust. I had some plans to collaborate when I visited your facility, but unfortunately, due to the way I was treated, I decided not to proceed with any future business plans. I believe this is not a reflection of the owner, but rather an issue with employee conduct. Proper training and customer handling can significantly improve business growth and reputation. As I do not have a direct contact, I am sharing this feedback here. If you would like to discuss further, please feel free to contact me. Our recent bill was under the name Electro Instruments.
