A couple of weeks ago, we covered PineTime smartwatch for PinePhone Linux smartphone that should be launched next year for around $25.
At the time we had limited information from a Tweet as well as information provided by TL Lim, founder of Pine64 community, such as the watch would be based on Nordic Semi nRF52832 or nRF52840 multi-protocol WiSoC. But we now have much more details about specs and other details can be found in the Wiki.
- SoC (undecided, one or the other. See differences between nRF52832 and nRF52840 for details)
- Nordic Semiconductor nRF52832 Arm Cortex-M4F MCU @ 64 MHz with 512KB Flash, 64KB SRAM, Bluetooth 5 (no long range)
- Nordic Semiconductor nRF52840 Arm Cortex-M4F MCU with 1MB flash, 256KB flash, Bluetooth 5 (long range), 802.15.4 (e.g. for Zigbee), Arm Trustzone, etc…
- Storage – 8MB SPI NOR Flash (final product may use 16MB flash instead)
- Display – 1.3″ 240×240 IPS capacitive touchscreen display with 65K colors
- Connectivity – Bluetooth 5 Low Energy (and others if nRF52840 selected)
- Sensors – Accelerometer, PPG Heart rate sensor
- Misc – Vibrator
- Built-in 170-180mAh LiPo battery
- Charging – Proprietary 2-pin 5V/500mA
- Dimensions – 40 x 37.5 x 11 mm (zinc alloy and plastic body)
- Weight – 38 grams
Note most of the specifications are for the prototype, and bound to change in the final products. Depending on community support the watch is expected to run various open source RTOS such as Zephyr, FreeRTOS, Arm Mbed or NuttX.
The wiki also provides some more information about availability and pricing. The development kit will come out in October 2019, while the final products is expected to start selling on Q1 or Q2 2020.
Price for the watch will be even lower than $25, as the PineTime watch with charging cradle will sell for just $22.99, and that’s the price you’ll pay if you already have a 20mm generic wrist band. The wrist band itself will be offer as a $2 option with a choice of material from silicone, NATO, Milanese steel, leather, and others.
