Introduction to the PineTime Pro

Summary

All blog postsTable of contentsIntroducing the PineTime Pro The PineTime Pro was officially announced at FOSDEM26 on the Pine64 stand. The demo was a bit modest (more on that later on), but we were delighted to showcase the first prototype of the “next generation PineTime” along with a demo running on a development board!We also mentioned the PineTime Pro in the FOSDEM 2026 Update blog post. In this blog post, we would like to provide a more in-depth look at the PineTime Pro.Why “Pro” and not “PineTime 2” The PineTime project started in October 2019, that’s more than 6 years ago! Needless to say, the PineTime has been a great success. The community has been very active in developing firmware for the device, companion apps, tools and more. And, according to PineStore, it sells very well.The reason the PineTime Pro isn’t called the PineTime 2 is because it’s not meant to replace the original PineTime.

It will continue production alongside this new model.The PineTime Pro should be seen as a more powerful, more feature-rich sibling rather than a direct successor. If the original PineTime is a solid open smartwatch platform, the PineTime Pro is our attempt to push that idea much further with new and improved components.What makes it “Pro” Compared to the “OG” PineTime, the PineTime Pro brings a significant hardware upgrade.At its core is a dual-core Cortex-M33 SoC, with one application core running at up to 200 MHz and a dedicated Bluetooth core. It also comes with 800 KB of internal SRAM and 8 MB of PSRAM.Around that MCU, the hardware currently includes:Bluetooth 5.2 - Classic (BR/EDR) & Low EnergyA 410×502 AMOLED display with touch supportA digital crown that also acts as an extra buttonGPSA heart rate sensor with blood oxygen measurement capabilityImproved accelerometer -> full 6D Interial Measurement UnitAn I...
