Watchy is a completely open source and customizable e-ink screen watch. It uses ESP32-PICO-D4 as the core, has WiFi and Bluetooth LE connectivity, and is compatible with Arduino, MicroPython and ESP-IDF. The 200x200 pixel resolution e-paper display is clearly visible in bright sunlight and has ultra-low power consumption.
NXH3670ADK development kit
In the open source electromyography project shared here, the author used this product to create a computer game control effect.
Highly Scalable QN Wireless MCU Application Development Platform This development kit is enabled by the QN9090T which supports Bluetooth 5 and NFC.
This user manual describes the different user configurations of the NxH3670 SDK board.
Have you ever thought about attaching an inertial measurement unit (IMU) to an object to track its posture and motion? Tracer provides high-performance, safe, reliable and low-cost object tracking. Tracer can be easily attached to objects using Velcro. It can tilt and track rhythm as the bike's frame tilts, it can record the number of shots taken with a tennis racquet, and it can even differentiate between topspin and chip shots. Let your imagination run wild and explore more interesting applications of Tracer!
Robust composite video transmission solution with output short-to-battery protection
NXP is launching a Generation 2 USB Type-C Shield with display port alt mode support! The NXP Generation 2 USB Type-C shield works with the MCUXpresso SDK and USB Power Delivery stack to allow you to connect USB Type-C Connectors to select Kinetis®, LPC and i.MX RT development platforms.
QN9080SIP-DK is a development kit supported by the QN9080-001-M17 module, supporting Bluetooth 5 and NFC.
Reliable health monitoring has traditionally required us to tether ourselves to machines that record our vital signs around the clock. However, outside of clinical settings this is rarely practical. We developed HealthyPi v4 in part to address this challenge. Building on its predecessor, HealthyPi v4 is a fully open source standalone vital signs monitor with wireless and wearable capabilities.
The SABER board for smart devices is based on the i.MX 6SoloX processor and supports 4-core processing, low-power multimedia and graphics applications.
A smart wearable device based on the RSL10 development board officially provided by EEWORLD. This device is divided into two parts: the host and the slave. However, this MCU only has one UART, but in actual project requirements we need to use two UARTs. The organizer of this event gave five boards, so a board without a sensor is used as the SPI slave and will receive The command parses and uses AT commands to control the audio.
The Sensor Watch is unlike most smartwatches.
Based on DA14580_ADXL362 schematic diagram (Xiaomi bracelet solution)!
This project is a completely open source smart watch based on the ESP32 WROOM module, with a very high degree of completion. In the project design, serial communication and charging are completely through the onboard micro USB interface, without any external interface board processing.
It adopts Qinheng's self-developed RISC-V microprocessor "Highland Barley V4" and integrates 2Mbps low-power Bluetooth on the chip. It is equipped with a blood oxygen and heart rate module, a nine-axis sensor, a motor drive module, a low-power touch detection module and a 0.96-inch high-definition IPS display to meet the application needs of general bracelets.
You can record your life anytime and anywhere, remember people's names, calculate food calories, translate in real time, and have intelligent conversations...
