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.
