IntroductionThe 3.26 Yuan Bluetooth mouse is likely a product that only the domestic Industrial Cthulhu can offer at such a low price while still being functional. With a Bluetooth chip, PCB, BOM, and structure, it seems impossible for the cost to be covered, especially with free shipping! It could be a promotional product, but they probably won’t lose too much; even during promotions, cost control is essential. So, I’m curious about the internal components of this Bluetooth mouse. How do they control costs?AppearanceThis mouse is relatively compact, suitable for business trips or temporary use, but it doesn’t feel great for long-term use due to its small size.However, the design is quite fresh, featuring a blue and white color scheme. The mouse is also flat and small, making it ideal for users with smaller hands, possibly designed for tablet use to ensure portability.
It uses batteries, with a switch on the back and specific parameter information.
It uses two AA batteries.
In terms of usage, the button feel is decent, responsive, and relatively quiet. However, it is quite small, making it uncomfortable for prolonged use.DisassemblyDisassembly is straightforward; just open the battery cover and unscrew this screw.
Remove the panel, which is secured by clips.

The first two clips are quite tight, so you need to apply some force to pry them open.
Upon seeing the internal structure, the button and scroll wheel section uses low-cost tactile switches, but the middle button is a standard tactile switch, while the left and right buttons are silent switches.
The core optical component, the mouse sensor, is the MAX8699.
Remove the PCB.Looking at the back of the PCB, it is quite simple, with no peripheral components, just a few resistors and capacitors, a switch, a crystal oscillator, and an LED.
Now, let’s look at the main component, the Bluetooth chip, which is the YC1011-N using a PCB antenna.It belongs to the Yizhao Micro YC10XX series.
I found only one retailer on Taobao, and it’s not cheap. I wonder what the price would be for bulk orders.
ConclusionOverall, this mouse functions well, and the user experience is satisfactory. It is perfectly fine for business trips and temporary use.For a mature product like a Bluetooth mouse, the integration is very high; the core components are just a sensor and a Bluetooth chip, in this case, the MAX8699 and YC10xx, which can be produced cheaply in large quantities. Therefore, it’s possible to find decent mice for just a few dollars. Of course, buying a Bluetooth mouse for 3.26 Yuan is likely a loss for the seller, mainly to attract attention during promotions, but only the domestic Industrial Cthulhu can achieve this. It is indeed a benefit of industrial development.
