LILYGO Mini E-Paper Core IoT controller gets ESP32-S3 wireless microcontroller

LILYGO Mini E-Paper Core has gotten an upgrade to the ESP32-S3 wireless microcontroller. The IoT controller was first introduced in 2021 with an ESP32-PICO-D4 system-in-package, a 1.02-inch E-Paper display, and a few GPIOs on the back, and the company kept the same design for the ESP32-S3 model called “Mini E-Paper Core S3”. The tiny ESP32-S3 IoT controller can still be used for integrated into your own project, and the company also provides several shields with nRF24L01 2.4GHz wireless or 433/868 MHz “LoRa” connectivity to transform the device into a longer range IoT device. Mini E-Paper Core S3 specifications Wireless SoC – Espressif Systems ESP32-S3FN4R2 CPU – Dual-core Tensilica LX7 @ up to 240 MHz with vector instructions for AI acceleration Memory – 512KB RAM, 2MB PSRAM Storage – 4MB flash Wireless – 2.4 GHz WiFi 4 and Bluetooth Storage – MicroSD card socket Display – 1.02-inch e-paper display with 128×80 […]

Review of SONOFF BASICR4 Smart Switch and S-MATE2 Smart Remote Control

Sonoff SMATE-2 + BASICR4 automation demo

We’ve received two new devices from SONOFF for testing, namely the BASICR4 Smart Switch and the S-MATE2 Smart Remote Control. For those familiar with SONOFF devices, the Basic series is well-known as it was one of the initial products SONOFF introduced to the Smart Home market. It’s a Wi-Fi switch that can be used for various purposes, including controlling lights, fans, and other electrical devices. The BASICR4 model enhances capabilities while reducing costs compared to its predecessor. The S-MATE2, on the other hand, is the second version of a simple Remote Controller powered by batteries. It wirelessly connects to other SONOFF devices that support the eWeLink Remote Gateway feature, enabling full control within the same ecosystem. This expands its usability across different devices. Let’s delve into the details. SONOFF BASICR4 Introduction The Basic series has been a long-standing Wi-Fi Switch family allowing control of electrical devices through the eWeLink app […]

AirGradient ONE Kit Review – An open-source indoor air quality monitor

The product we are reviewing today is the “AirGradient ONE” air quality monitor kit which is an updated version of the earlier AirGradient air quality monitor. The device is equipped with sensors from Sensirion and Plantower, allowing it to measure many air quality parameters such as CO2, PM2.5, TVOCs, NOx, temperature, and humidity. It is an indoor air quality monitor that is both open-source software and open hardware. This means that the Arduino source code, schematic diagrams, PCB, and 3D models of the enclosure are available to developers. AirGradient ONE DIY Kit Unboxing The device was packaged within a cardboard box, with a greeting card from the manufacturer. The card features a QR code linking to a webpage with the installation guide. Since I requested the Kit version (there’s also a fully assembled model), some sensors were not pre-assembled and they were well-packaged in separate seals. The main PCB was […]
