Overview

This is a totally hand-made watch, but wait... we won't made it for you. The only one that can bring it to life, is YOU!

Functionality

Default functions :

More :

• Step counter & Timer (coming soon in V2.0)
• Customized functions

PS : all the functions can be modified based on the open source program, up to you.

Features

• Case : actually, there's no case. It is formed by stacked PCBs. 
  
• Gesture sensor : steel ball combined with PCB copper pads. ZERO power consumption if no gesture detected, not like any other sensor. 
  
• Button : pressure-sensitive buttons, achieved by copper pads on two adjacent PCBs with very little clearance. 
  
• Monitor : 1.3inch 128x64 OLED.  
  
• RTC : high precision RTC chip RTC8025.
• Temperature sensor : high accuracy sensor LM75.
• Battery : wireless magnetic charger & rechargeable lithium battery, up to 15-30 days standby time after fully charged.

Note :

• For programming the DoWatch, you need a serial module : CP2102 USB UART Board (mini) OR CP2102 USB UART Board (type A)
• This is a DIY kit, soldering tools and soldering experience for LQFP chips are required.     (If there's any problem, we are happy to solder the MCU and OLED for you, just leave us a message while placing an order)   
• Double-sides tape, clamps, are also needed for installation but not included in the kit.
• The default  program is still under developing, functions like timer/step-counter are unavailable for the moment, and maybe there are some BUGs (we'll fix them on the follow versions)
• If any component is opened or soldered, which means the kit can not be sold anymore, therefore, refund or return won't be accepted, hoping for your understanding.
