Ridiculously tiny ESP32-C3 board features USB-C, one LED, and a ceramic antenna

PegorK’s f32 might be the world’s smallest ESP32-C3 board. It measures just 9.85 x 8.45 mm, or slightly larger than the area covered by a USB Type-C connector. A board of this size will have limited features, and besides the ESP32-C3FH4 RISC-V WiFi and Bluetooth microcontroller, it comes with a USB-C port, a ceramic antenna, and a single GPIO pin connected to an LED. f32 specifications: SoC – Espressif Systems ESP32-C3FH4 Single-core 32-bit RISC-V microcontroller @ up to 160 MHz Memory – 400 KB SRAM Storage – 4MB flash Wireless 2.4 GHz Wi-Fi 4 & Bluetooth 5.0 USB – 1x USB Type-C port for power and programming Misc Tiny LED connected to GPIO10 Ceramic antenna Crystal Power Supply – 5V via USB-C port; 3.3V LDO Dimensions – 9.85 x 8.45 mm (the height must be around 4-5 mm) The PCB was designed using DipTrace and manufactured with a board thickness […]

Review of SONOFF’s latest Matter Smart Switches – Basic Gen5 and Tx Gen2

Today, we’re about to review not one, but two new Matter devices: the SONOFF Basic Gen5 Smart Switch and the SONOFF Tx Gen2 Smart Wall Switch. Both are upgraded versions of their previous models, now adding support for the Matter protocol (over Wi-Fi). The Basic Gen5 is the fifth generation of the popular Basic series, known for being affordable and widely used in the market. It’s a Wi-Fi smart switch that can control all kinds of devices, such as lights or small electrical devices. Basically, anything within its 10A limit. What’s new compared to the previous BasicR4 is the addition of Matter and near-field control via Bluetooth. As for the Tx Gen2 (T6), it’s an upgraded version of the older T2/T3 lineup. Besides adding Matter, it also brings a few new features, like adjustable backlight brightness and the Detach Relay mode. Both models support voice control via Apple Siri, Google […]

Waveshare MK20 macro keyboard features twenty mechanical keys with 0.85-inch color LCD keycaps

Waveshare MK20 Multi Functional AI Voice Control Panel

Waveshare MK20 is a multifunctional macro keyboard with twenty mechanical keys featuring 0.85-inch LCD keycaps. As an upgrade to the earlier MK10 model, it adds a 2.8-inch secondary display along with two control knobs. The device supports AI voice interaction, real-time data display, and smart home integration with Home Assistant. Like its predecessor, the MK20 relies on a dual-system architecture: an Allwinner T113-S3 dual-core Cortex-A7 processor runs Linux to drive the displays, and a GD32 microcontroller runs QMK for low-latency keyboard and knob input. Each LCD key offers 128×128 resolution and supports dynamic images, videos, and multi-layer overlays, while the 2.8-inch secondary display (428 × 142 resolution) provides status or customization information. The keyboard also includes two rotary encoders with aluminum caps for volume, playback, or timeline control. The device is built with an aluminum alloy top case and a 2.5D acrylic lens for durability. Waveshare MK20 specifications: Main Controller – Allwinner […]

ESP32-based dual-port WLED controller features Ethernet port, 24V DC input

When it comes to ESP32-based WLED controllers, some of the best options are boards like the Adafruit Sparkle Motion, Mini Sparkle Motion, and Sparkle Motion Stick, but most of the time, they are out of stock. Thankfully, there are similar alternatives like the xChroma WLED Type-C and HACK Lab HackLED Pro, with similar features and wider availability. Now adding to that list is the 2-Port ESP32 ETH0 WLED Controller, which not only adds Ethernet connectivity but also supports dual outputs and 5V–24V LEDs, making it an excellent alternative to the Adafruit ones. The board supports both Ethernet and Wi-Fi connectivity and includes an onboard DC-DC converter that delivers a stable 5V supply to the ESP32 and logic circuits. Each output channel is fused with a 6A resettable polyfuse and a status LED that lights up during fault conditions. For added safety, the main power input is protected against reverse polarity, […]
