F2 will be changed to F2-H, with the LD1125F module being replaced by the LD1125H; whilst they have the same structure, the latter appears to offer superior performance.

We are delighted to be able to manufacture a large number of F2 units; however, as the supplier has upgraded the modules, the LD1125F will be replaced by the LD1125H, and we will follow this update by using the LD1125H, which features a superior design.

The difference appears to lie in the control circuitry.

At the same time, due to rising costs, the price of each F2 will increase by $3.

Whenever possible, we aim to extend the lifespan of these sensors as much as we can, ensuring they do not become mere fleeting DIY fads. For those who love them, we hope to continue manufacturing them indefinitely.

Thank you for your understanding :)
