MyoWare 2.0 Muscle Sensor Wireless Kit targets electromyography (EMG) applications

MyoWare 2.0 Muscle Sensor with ESP32 Arduino board

The MyoWare 2.0 Muscle Sensor Wireless Kit is an Arduino-compatible electromyography (EMG) sensor kit capable of detecting and measuring the electrical signals generated by muscle fibers in the body. The MyoWare 2.0 kit is a collaborative product by SparkFun and Advancer Technologies. The MyoWare 2.0 ecosystem brings several improvements over the previous generation, including a compact design, solderless snap connectors, and an upgraded chipset for improved reliability and performance. It includes shields designed to seamlessly interface with the MyoWare 2.0 Muscle sensor, a wearable, Arduino-compatible EMG sensor. The Muscle Sensor’s wearable design makes it possible to directly attach biomedical sensor pads and add-on shields to the board. It operates on a single-supply voltage between +3.3V to +5V and supports three separate output modes. It analyzes filtered and rectified activity from muscle movement and outputs a signal from 0 to the power source voltage (VIN) that represents the intensity of flex. […]

Zigbee Coordinator CC2652P7 1.0 runs open-source firmware, works with Zigbee2MQTT, Home Assistant, and ioBroker

The cod.m Zigbee Coordinator 1.0 (CZC 1.0) is a hybrid ZigBee coordinator that can be used to connect devices over a network (Ethernet/Wi-Fi) and USB. The ZigBee Coordinator version 1.0 is an upgrade of version 0.2 released in 2022. The CZC 1.0 replaces the Texas Instruments CC2652P2 chip with the much more powerful CC2652P7 chip, uses an ESP32-WROOM-32E module instead of the USR-K6 chip, and adds compatibility with Home Assistant (ZHA integration). It can create a Zigbee network and pair Zigbee devices over Ethernet, WiFi, or Serial (USB). It features the same Texas Instruments CC2652P7 chip as the SMLIGHT line of Zigbee Ethernet/WiFi/USB coordinators and USB dongles. There are two models of the CZC 1.0: a Power over Ethernet model and a model that can only be powered via USB-C. cod.m Zigbee Coordinator specifications: Zigbee SoC – Texas Instruments CC2652P7 Arm Cortex-M4F microcontroller @ 48 MHz with 704 KB flash, […]

LILYGO T-Energy-S3 ESP32-S3 board offers 18650 battery holder, two 20-pin GPIO headers

ESP32-S3 board with 18650 battery holder

LILYGO T-Energy-S3 is an ESP32-S3 WiFi and Bluetooth IoT board with an 18650 battery holder, a USB-C port for charging and programming, and plenty of I/Os thanks to two 20-pin GPIO headers and a Qwiic connector. We’ve already covered a large number of ESP32-S3 boards and products, including some designs for battery operation such as the Tokay Lite AI camera board, LILYGO’s T7-S3 board, and Smart Bee Designs’ Bee S3 board among others. But that usually means providing a 2-pin connector and charging circuitry to connect a LiPo battery, but the T-Energy-S3 ESP32-S3 board works directly with an off-the-shelf 18650 rechargeable Lithium battery. T-Energy-S3 specifications: Wireless Module – ESP32-S3-WROOM-1-N16R8 Espressif Systems ESP32-S3R8 – Dual-core Tensilica LX7 @ up to 240 MHz with vector instructions for AI acceleration, 512KB RAM, 8MB PSRAM Storage – 16 MB flash Wireless – 2.4 GHz WiFi 4 and Bluetooth PCB antenna USB – 1x USB […]

ESP32-S3 rotary encoder features 1.2-inch AMOLED touchscreen display and Qwiic connectors

LILYGO T-Encoder-Pro is a rotary encoder based on Espressif Systems ESP32-S3 WiFi and Bluetooth SoC, equipped with a 1.2-inch AMOLED with touchscreen support, and two Qwiic connectors for expansion. LILIGO T-Encoder was introduced in 2022 with ESP32 WiFi and Bluetooth SoC and a few GPIOs that enabled it to be fitted on a 2-key keypad shield. The LILYGO T-Encoder Pro has a completely different design with a more advanced ESP32-S3 SoC, an integrated touchscreen display, and GPIOs are now exposed through Qwiic connectors instead of headers. LILYGO T-Encoder-Pro specifications: Wireless SoC – Espressif Systems ESP32-S3R8 CPU – Dual-core Tensilica LX7 @ up to 240 MHz with vector instructions for AI acceleration Memory – 512KB RAM, 8MB PSRAM Wireless – 2.4 GHz WiFi 4 and Bluetooth Storage – 16 MB flash (W25Q128) Display – 1.2-inch rounded AMOLED with ∅390mm resolution via SH8601A-W14-T06 QSPI controllers; CHSC5816 I2C touch and rotary encoder chip […]
