It has micro USB and USB Type-C ports that you can use to connect the T-Wristband to a computer for programming. The expansion board gives you access to GPIO and UART pins as well as other functions. There’s a clock chip for keeping time, and an 80 mA rechargeable battery. The device features a 0.96 inch IPS color display with a TTP223 based touchpad, an ESP32-PICO-D4 processor, a sensor for motion sensing, and support 802.11 b/g/n WiFi and Bluetooth Low Energy. Sensor : LSM9DS1 (LSM9DS1 is an alternative sensor for MPU9250).Antenna : Built-in WiFi / Bluetooth Ceramic Antenna.Expansion / Program Download Interface : 0.3 pitch 13pin FPC socket.Battery : 350926 / 55mAh Rechargeable Lithium Battery(Normal Versions) 361523 / 105mAh Rechargeable Lithium Battery(Battery Plus Versions).Built-in Chip : 520 KB SRAM, 802.11 b / g / N HT40 Wi-Fi transceiver, baseband, protocol stack and LWIP, integrated dual-mode Bluetooth (traditional Bluetooth and BLE Bluetooth low energy).Processor : Tensilica LX6 dual-core processor, clocked at 240MHz, computing power up to 600DMIPS.It comes with an expansion board with additional I/O ports for programming the smart band. But this inexpensive wearable device is a programmable device that can run custom software. TTGO T-Wristband looks like a Xiaomi Mi Band 4 clone. TTGO T-Wristband DIY Programmable Smart Bracelet The OS is still in early beta stages, and as such, only has basic smartwatch functions and features like a calculator, calendar, stopwatch and heart rate monitor and cannot replace Android Wear as your daily driver completely. AsteroidOS is an open source operating system, designed to be run on smartwatches.ĭeveloped by Florent Revest, AsteroidOS is a flavor of Linux for smartwatches. They even extend beyond Android, thanks to the likes of Tizen and iOS, offering consumers a choice in hardware and software if they so desire.īut, what if you want an OS on your hand (quite literally at that) that is entirely open source? What if you wish to have complete control over how your data is handled, how your watch behaves and how easily and quickly it is updated? What if you simply want to escape the clutches of big name corporations and go for something that is much more community oriented and not hungry to know everything there is to know about you? From early-hardware gimmicks to actual, indispensable devices that improve our workflow and productivity, smartwatches have created their own niche in the Android ecosystem. ![]() Long holdTime_us = (long)(1.0 / (double) stepsInFullRound / speedRPS / 2.This is not a watch but an opensource smartwatch OS, AsteroidOS is an opensource operating system available for LG G Watch Urbane, Asus Zenwatch 2, LG G Watch R, and many other watches.Īndroid Wear, the OS specialized for running on smartwatches, has changed the way we perceive wearables. ![]() A custom delay function used in the run()-method connect GRD to power source (9v battery - term)īoolean stepDirection = 0 //rotation directionĭouble speedRPS = 7 //initial speed of stepperĪttachInterrupt(0, doEncoderA, CHANGE) // encoder pin on interrupt 0 (pin 2)ĪttachInterrupt(1, doEncoderB, CHANGE) // encoder pin on interrupt 1 (pin 3) connect VMOT to power source (9v battery + term) connect GND to Arduino GND (GND near VDD) And this is my arduino code : //simple A4988 connection
