This is the PineTime. A companion for your Linux smartphone, and new side-project of ours. More news coming in the future...

(If you have experience with FreeRTOS or mbed, and are interested, please get in touch!)

@PINE64 @ajroach42 On the one hand, awesome!

On the other hand, insufficient buttons :(

(One of the most useful aspects of smartwatches is they can add hardware buttons to be used to control one's smartphone; great for instance for controlling audio playback and volume on the go. The fewer physical buttons the less useful this is.)

@keithzg @ajroach42 @PINE64 totally agree on the insufficient buttons - but they're using an existing hardware shell from Chinese manufacturers so that's pretty much fixed :<

@PINE64 All I meant was a color, always on display with an accessory port. :-P

@gudenau @PINE64 I'm perfectly fine with the idea of this being a "Pebble Time"-esque watch since it'll save me a lot of work with making my own Pebble to replace my current Time when its battery finally dies :blobsob:

I started studying mbed and everything! :blobthinkingeyes:

@polychrome @PINE64 I have a Kickstarter Time. 👌

Part of me wants to buy a regular Steel and get someone to plate it with real gold.

@PINE64 @freakazoid huh, the first commercial product I’ve seen using mbed

@PINE64 holy fuck please, my pebble is starting to lose it.

Yes, please! I would like a smart watch, not an activity tracker. e-ink with notifications, alarms, and calendar would be awesome.

@PINE64 Hope it could compare to Fitbit for fitness tracking.

Looks like its a good time for FOSS and hardware alternatives to apple and android! This the #librem5 and #pinephone :blobaww:

@PINE64 Wow, that's actually a great idea. I might even buy this lol

@PINE64 give me some documentation of the board when it's ready and I will see what I can do.

I've read somewhere you're using a nordic chip, correct? They tend to be well supported by zephyr.

@dwagenk Correct, Nordic nRF52832 SoC, with an additional 8MB/64Mbit NOR flash chip. Bosch BMA421 accelerometer.

If you're really interested, email about this. Also may want to keep track on one of our chat platforms (look at Community tab on

@PINE64 please have a talk with the guys! They are developing afreertos based os for watches like this!


We're definitely interested in working with Rebble! We've had trouble getting a response from them, however.

The hardware isn't really conducive to that. The main SoC inside is a nRF52832 (Cortex-M4 @ 64Mhz)

@PINE64 ok but can that first XI change to a IX or nah?

@PINE64 since it seems you are syill choosing the guts perhaps its good idea to rather then following android watch / apple crap be mkre pragmatic. Using e-ink display like in.pebble (l'm owner of one) is amazing. The display stays on all the time displaying time without any battery loss. Batrery lasts a week on one charge. The ui and notifications are clear and do what they suppose.

@muppeth Unfortunately we can't make that happen at the price point we're looking for.

We are still looking at multi-day battery life with significant (if not always-on) screen on time.

@PINE64 I guess this is right now just a CGI picture, where can I get more info about that?

@jeena The watch in the picture is an actual prototype. The background obviously is CGI. ;)

@PINE64 PLEASE let me help, lol. Like I will do a lot fo this lol


If you think you can help, email with what you think you can offer. :)

@jalcine i'm so hyped i wanna get Rust shit running on this

@er1n I'm very down - if there's some kind of emulation layer to even get started, I'd spend time on it. It looks like it'd be WILD cheap too

@jalcine yeah you could probably do something with like uh qemu-arm and writing a generic video driver that spits draw commands out of the qemu monitoring serial port is also super cool, wild real-time concurrency toolkit

@PINE64 I generally don't get that excited about smart watches but a truly FOSS one sounds nice. Bonus points if it doesn't have to be charged every day.

Me want, me want badly, me want now! 👍😎👍
