ESP32 Smart Bracelet Fitness Tracker Band Programmable with Arduino

This Smart Bracelet is an electronics tinkerer dream! A fully programmable fitness band that requires no messy wiring or additional components to get started — it carries its own CP2104 USB to Serial chip. Just pop out the micro-USB metallic cover and connect it to a computer for modifying its default firmware or loading up your own code. Powered by an ESP32-PICO-D4 dual-core wireless System-on-Chip (SoC) with 520KB SRAM, this fitness band is fully programmable and customizable.

Inside, this device has a built-in ceramic WiFi/Bluetooth antenna for improved signal quality. Outside, it offers access to a beautiful, 0.96-inch IPS colorful screen (ST7735 driver) and a DRV2605 haptic sensor interface (built-in push button).

The fitness band also features onboard sensors that communicate their readings to the ESP32 SoC. These include a LSM9DS1 9-DOF Inertial Measurement Unit (IMU) to measure movement whose measurements are used by built-in step counting, activity recognition/tracking, and advanced gesture recognition algorithms. And, a MAX30102 sensor for measuring heart rate. The smart fitness band also carries a 55 mAh rechargeable lithium battery.

Features:

• Easily get started with code that runs on a fitness tracker. Connect the included programming board, carrying a CP2104 USB to Serial chip, for programming it!
• Powered by an ESP32, this fitness band is compatible with a wide array of Arduino and IDF libraries
• The Smart Bracelet’s haptic sensor is a great way to practice and improve your User Interface (UI) skills
• The onboard LSM9DS1 IMU provides the necessary data for counting steps, tracking activity, and more!
