ES121 Mini Electric Screwdriver has set a new standard for electric screwdrivers. It is an electric screwdriver with a compact structure,  smart and exquisite appearance, as well as the function of motion control recognition.

It has only the length of a Parker pen, while endowed with a comfortable design for holding, and a set of highly energy-efficient accessories. Through an OLED screen, the device displays parameters and rotation modes of motion-control recognition. Under these help, you are able to easily complete the disassembling and assembling of your digital devices.

ES121 includes a planetary gearbox and a high-speed electric motor, with excellent support from the STM32 embedded micro-processor and angular velocity sensor. It operates at a voltage range of DC3V to 5V, and with various hexagonal screwdriver bits, the device helps you with fast disengaging and engaging of electronic products.
