TinyWatch S3 is an open-source, customizable smartwatch powered by ESP32-S3 SoC

tinywatch s3

The TinyWatch S3 is an ESP32-S3 development board in a smartwatch form factor from Seon Rozenblum, also known as Unexpected Maker. It is powered by the ESP32-S3 wireless microcontroller with 8MB quad SPI flash storage and 2MB of additional QSPI PSRAM. It features a 240 x 280 LCD with capacitive touch (via a CST816T module) and several onboard sensors including a 6-axis inertial measurement unit, a magnetometer, and a MEMS microphone. It has a USB-C port for power, programming, and charging a connected LiPo battery (250mAh or 500mAh). While the product’s firmware is still in active development, it is usable as a watch and even a daily driver. The TinyWatch S3 is described as a “wrist-wearable ESP32-S3 development board” but lacks pin headers and is not breadboard compatible. The hardware is open-source but the product is mostly useful for firmware development, testing, and other general projects. The firmware is being […]

LILYGO T-Halow is an ESP32-S3 board with long-range WiFi HaLow, OV2640/OV5640 camera support

ESP32-S3 WiFi HaLow board

LILYGO T-Halow is an ESP32-S3 board equipped with a WiFi HaLow module with up to 1.2km range, a connector compatible with OV2640 and OV5640 camera modules, and an 18650 battery holder for power, as well as several GPIOs for expansion. We first wrote about 802.11ah low-power long-range WiFi standard operating at 900 MHz in 2014, but adoption has been slow and we’ve seen a few 802.11ah (WiFi HaLow) chips from Newracom and Morse Micro over the years, as well as USB adapters, a Raspberry Pi HAT, a mini PCIe card, gateways, and some development boards. All those rely on a Linux host, but the LILYGO T-Halow features a TX-AH WiFI HaLow module from Taixin Semiconductor that’s controller by AT commands through an ESP32-S3 or a micro USB port. LILYGO T-Halow specifications: Wireless modules ESP32-S3-WROOM-1 wireless module SoC –  ESP32-S3 dual-core Tensilica LX7 microcontroller @ up to 240 MHz with 2.4 […]

4.3-inch ESP32-S3 wireless touchscreen display features terminal block with RS485, CAN Bus, I2C, DIO

ESP32-S3 display RS485 CAN Bus terminal block

Waveshare “ESP32-S3-Touch-LCD-4.3B” is a capacitive touch display development board built around an ESP32-S3 SoC with RS485, CAN Bus, I2C, and isolated DIO interfaces provided through a terminal block. The devkit features a 4.3-inch capacitive touch display that has an 800×480 resolution, RTC, and a microSD card slot. Combined with a wide input voltage range of 7-36V DC, the ESP32-S3-Touch-LCD-4.3V is suitable for IoT HMI, smart home automation, and more. Previously we have written about similar development boards from Waveshare like the ESP32-S3 1.69-inch touch display, the $15 Waveshare 1.69-inch IPS touch LCD module, the Waveshare RP2040-LCD-0.99-B rounded display but they would offer no expansion pins or GPIO through pads or 4-pin connectors, while the ESP32-S3 display features a terminal block with additional interfaces like RS485 pr CAN Bus that should make wiring more convenient and versatile for the target applications.

qsen 07 multi-sensor board

The Qsen-07 multi-sensor board is an ESP32 wireless development board that combines several useful sensors into one device, making it easier to control, monitor, and enhance your home environment. It is a recent product from Maker Go, a China-based hardware company, which claims the board is “fully integrated with ESPHome and Home Assistant“. But as noted in a reader’s comment below, ESPHome on ESP32-C6 is still a work in progress, and the YAML configuration file for the board has yet to be provided by the company. The Qsen-07 multi-sensor board is “designed for health-conscious and tech-savvy homeowners” and can monitor air quality and other environmental variables to ensure a safe and smart living space. It features up to seven sensors, including two air quality sensors, a temperature and humidity sensor, an ambient light sensor, a barometric pressure sensor, an attitude gyro sensor, and an optional radar sensor.
