FireBeetle 2 ESP32-C5 IoT development board offers GDI display interface, LiPo battery support

Just the other day, I lamented the lack of options when it came to ESP32-C5 boards featuring dual-band WiFi 6 support. The FireBeetle 2 ESP32-C5 IoT development board made by DFRobot shows that I needed to be more patient… The ESP32-C5 board features 4MB flash, a USB-C port, a LiPo battery connector, and two GPIO headers for expansion, as well as a GDI display connector designed to add an SPI/I2C touchscreen display. The new RISC-V board has about the same features and form factor as the FireBeetle 2 ESP32-S3. It adds 5 GHz WiFi and an 802.15.4 radio for Zigbee, Thread, and Matter, but loses a camera connector, and comes with less memory and storage. FireBeetle 2 ESP32-C5 specifications: Wireless module – ESP32-C5-WROOM-1-N4 SoC – Espressif Systems ESP32-C5 CPU Single-core 32-bit RISC-V processor @ up to 240 MHz Low-power RISC-V core @ 40 MHz acting as the main processor for […]

Weffort Outdoor Smart Shade Review with Home Assistant over Matter/Thread

We’re going to do a quick review of smart outdoor motorised shades from Weffort — another brand that makes smart shades compatible with popular Smart Home platforms, including Home Assistant, SmartThings, Google Home, Apple HomeKit, and Amazon Alexa. The cool thing about Weffort’s shades is that everything’s fully customisable and made-to-order — from the fabric and motors to casing styles, size, and the Smart Home platform you want to use with. With various options, it might sound complicated at first (usually people just let a pro handle it), but it’s actually way easier than you think. Plus, the shades are lightweight, so you can totally install them by yourself. Custom-made shades Before we got the test unit from Weffort, they let us locate a good spot for installation and testing so that we could take measurements following the guide on their website, which also has tips on choosing materials, installation, measurements, […]
