Pedometer

The 3D pedometer is a wearable healthcare product. It has a built-in three-dimensional acceleration sensor IC and can generate three-dimensional acceleration values ​​and direction values. It must contain a microcontroller to read three-dimensional data through the I²C bus, and execute an algorithm to measure walking distance, running distance and calculate the calories burned, and record daily exercise information to analyze the individual's exercise energy consumption status, and Data display and data storage. The 3D pedometer provides data upload function to computers, tablets, and smartphones. Communication via USB 2.0 HID or using Bluetooth Low Energy BT 4.0 BLE with App application software. Due to the need to operate at very low power consumption and long standby time with battery power, the Nano130 series is suitable for 3D pedometers. The Nano130 series provides high performance, low cost, ultra-low power consumption 32-bit Arm® Cortex®-M0 core, running speed Up to 42 MHz, built-in 32-bit hardware multiplier, low operating voltage 1.8V ~ 3.6V, ultra-low power consumption, operating mode (<200 microamps/MHz), power-down mode (real-time clock + LCD display on, memory data saving < 10 uA), (real-time clock, memory data storage < 2.5 uA), deep power-down mode (memory data storage < 1 uA), flash memory up to 128 KB and internal memory up to 16 KB, highly integrated RTC, LCD driver controller , 12-bit ADC conversion rate up to 2 Msps, built-in 12 MHz RC oscillator and USB 2.0 full-speed device to reduce system BOM cost. Rich peripheral interfaces I²Cx2, SPIx3, UARTx5 and anti-theft copy lock code bit function, 96-bit UID chip unique code, 128-bit UCID customer unique code, strong anti-interference ability (ESD 8kV / EFT 4kV).
