I made a wearable smart watch with FPC soft board, so cool! [Copy link]

Did you know that FPC can not only be used as a connector, but also can be used in wearable devices, consumer electronics, medical equipment, industrial control equipment and smart home products?

Recently, a friend shared a wearable smart watch made of FPC in Jialichuang's "Firefly Project" . It can be folded and worn on the wrist. It is so cool!

Project Name: FPC Watch

Project author: lovelessing

Main controller: CH583M, 60MHz main frequency, 512K flash, 32K ram, with Bluetooth 5.0 BLE

Screen: OLED 12864, 4-wire SPI interface

Gyroscope: ICM20608, SPI&IIC

Independent buttons: 2

ADC: NTC temperature measurement, battery voltage measurement

Development environment: MountainRiver Studio

The strap is welded to the dial from the back through the pad, and the copper plating and hollowing ensure the transmission quality of the Bluetooth signal.

Two independent buttons can be used for download, reset or user input

Would it be better to have a color screen?

By the way, where is this battery?

It may be on the back, but this is just a concept, the strength cannot keep up.

You can add a shell. Jiali Chuang FPC is pretty good. The double-sided board was delivered within 24 hours.

Is it possible that he only showed the front and the battery is on the back of the strap?
