- 120MHz ARM Cortex-M4 processor (ATSAM4SD32)
- with secondary AVR co-processor
Flash & RAM
- 2MB of onboard flash and 160KB of RAM
- 1/4 of the onboard flash will be used by the OS
- The flash is permanent (non-volatile) storage.
- Bluetooth 4.0 BD/EDR + LE
- Bluetooth 4.0 is backwards compatible with Bluetooth 2.1, so classic Bluetooth functions (BD/EDR, SPP/AVRCP/PBAP/etc.) will work fine.
- HFP and PBAP for Caller ID and AVRCP for music control.
- PXP for tethering.
- For smartphone to smartwatch communication, we use GATT where available and SPP when GATT isn't supported by the phone.
- We don't support HDP, as we're trying to limit power-hungry Classic Bluetooth communication to a minimum.
You should be able to use sports and fitness profiles with GATT though; the programming model (same as used in Windows 8.1 apps) is pretty flexible and you can basically implement application profiles in C#, grab profile classes off the web and incorporate them into your project, etc.
- 3D Accelerometer (Motion) ST LSM303DLHC
- Ambient Light Sensor
- Hardware power metering
- No piezo/speaker or microphone.
- Vibration Motor (we can pulse it to create vibration patterns, not sure about the vibration strength - driven with PWM)
- QI Wireless Charging, no NFC, no wall adapter included
- LED Backlight
- No GPS in the watch. It uses the GPS in your phone.
- AGENT watch apps are deployed and debugged wirelessly from your PC via Bluetooth.
- .NET Micro Framework 4.3
- RoHS, Pb-free
- we looked at microphone and speaker, and decided that they weren't right for the smartwatch for a few reasons: (a) battery life consumption; (b) water-tightness; (c) talking into a watch really isn't as awesome in the real world as we imagined it would be :)
- The back is not a stainless steel plate. The back has to be RV-permissive for wireless charging. You don't want your watch heating up :) And besides--the Qi chips are designed to shut off and not draw power if there's metal between the charging base and device's power receiver coil.
- Expected to use a CR2430-sized rechargeable battery - replaceable
- Estimated charging time from empty is 2 hours
- 7 Days typical with Bluetooth on, 30 days with Bluetooth off (watchface only mode)
- The battery should last at least 2 years, with 100s of charge cycles.
- The Qi charging plate does come with a USB cable that can charge from a PC or your wall adapter. We don't include a wall adapter because that really complicates international shipping and frankly everyone has one and we don't want to add to landfills any more than necessary.
- Roughly 38mm top-to-bottom on the front face,
- 35mm left-to-right on the front face,
- and around 12mm in depth.
- 22mm strap
- Two ~1/16" hex screws to attach the watch pin
- The top watchcase material candidates are PVD stainless steel, brushed matte ceramic, and high-quality polycarbonate (TBD).
- The glass lens is mineral glass, Anti-glare glass lens
- Leather and silicon straps will be available
- 1.28" Sharp Memory Display
- The display stays on 100% of the time.
- Dimensions: 128x128, 128.1 DPI
- "Pusher" buttons
- The top-left button activates the backlight
- Bottom-left changes apps
- Three buttons on the right are up/select/down and can be used for custom purposes by apps.
- Right middle button can be used for WatchFaces
- Backup reset procedure is currently activated by holding the home/menu button and the top-right user button for about ten seconds
The accelerometer is 3-axis and can certainly work as a pedometer. All you need is an app to pull that data up to the Internet. This is an important capability that we made sure was baked in.
We should add a drawing and dimensions to the main page with more exact figures, but for the moment: roughly 38mm top-to-bottom on the front face, 35mm left-to-right on the front face, and around 12mm in depth. The watch lugs add a bit to that near the base, snuggling your wrist, where they attach to the 22mm strap.
