Делаем любимую механику беспроводной: BLE-адаптер для Kingston HyperX Alloy FPS на базе Raspberry Pi Pico W

Продолжаю рассказывать о своём опыте создания BLE адаптера для USB-клавиатуры, которым уже пользуюсь каждый день. Собранный ранее на макетной плате адаптер с подключённым pico debug был хорош тем, что...

ESP32-S3 PowerFeather V2 board gains support for LiFePO4/LFP batteries

The ESP32-S3 PowerFeather V2 board is an ESP32-S3 WiFi and BLE IoT board with an Adafruit Feather form factor that supports LiFePO4/LFP batteries, as well as Li-Ion or LiPo batteries, and up to 18V DC input for solar panel connection. As one could have guessed, it's an update to the ESP32-S3 PowerFeather board introduced in 2024 with support for solar panel input, Li-Ion, and LiPo batteries. The V2 design is virtually identical, except it features an Analog Devices MAX17260 fuel gauge and a TPS631013 buck-boost regulator that keeps 3.3 V stable to add support for LiFePO4 batteries. Lithium Iron Phosphate batteries are said to be safer and longer-lasting than Li-ion or LiPo batteries, albeit at the cost of lower energy density. ESP32-S3 PowerFeather V2 specifications: ESP32-S3-WROOM-1-N8R2 SoC – ESP32-S3 CPU - Dual-core Tensilica LX7 up to 240 MHz Memory - 512KB SRAM, 16 KB RTC SRAM Wireless – 2.4 GHz

ESP32-S3 boards feature WAGO connectors for LED strips, buttons, other swappable modules

Rev Adrian Kennard (RevK) has designed several open-source hardware ESP32-S3 WiFi and Bluetooth IoT boards with WAGO connectors for interfacing LED strips, buttons, and other GPIO modules. Initially developed for the gloves and the helmet of an Iron Man suit, the ESP32-S3 boards can be used for any relevant project that needs more flexibility than soldered modules and more reliability than GPIO headers or even screw terminals, which can be susceptible to vibrations. WAGO push-in connectors make the ESP32-S3 boards especially suitable for prototyping and wearables, where being able to quickly swap modules is beneficial. The first board designed for gloves is called "Battery powered controller development board" with the following specifications: Core module – ESP32-S3-MINI-1-N4-R2 SoC – ESP32-S3 dual-core Xtensa LX7 processor with WiFi 4 and Bluetooth 5.0 connectivity Memory – 2MB PSRAM Storage – 4MB QSPI flash PCB antenna USB - 1x USB-C for power and programming Expansion

M5Stack PaperColor ESP32-S3 devkit features 4-inch E Ink Spectra 6 color display

M5Stack PaperColor, or M5Paper Color, is an ESP32-S3 development kit with a 4-inch E Ink Spectra 6 full-color display with a resolution of 600x400, designed to offer both low power consumption and high visibility under strong lights. While the color ePaper display is the start of the show, the devkit also features a microSD card slot for storage, a microphone with echo cancellation, a 1W speaker, a temperature & humidity sensor, a few buttons, two RGB LEDs, and an IR transmitter, but no GPIO expansion connectors. With regards to power, a 1250 mAh battery is included, rechargeable through the device's USB Type-C port. M5Paper Color ESP32-S3 Dev Kit specifications: SoC – Espressif ESP32-S3R8 CPU – Dual-core Tensilica LX7 microcontroller up to 240 MHz with vector instructions for AI acceleration Memory – 8MB PSRAM Wireless – 2.4 GHz WiFi 4 and Bluetooth 5.0 LE + Mesh connectivity Storage 16MB SPI flash

Clawdmeter – A DIY ESP32-S3 desk dashboard for Claude Code token usage monitoring

Clawdmeter is a DIY ESP32-S3-powered desk dashboard that displays Claude Code token usage on a 2.16-inch AMOLED screen so you know when you're about to reach the limits in real time. It's mostly a firmware project since it relies on off-the-shelf hardware (Waveshare ESP32-S3-Touch-AMOLED-2.16). It leverages the LVGL library for its graphics user interface, the NimBLE stack for Bluetooth LE (BLE) communication, and also functions as a HID keyboard for shortcuts using the buttons from the unit. We previously covered Waveshare ESP32-S3-Touch-AMOLED-1.8 with a 1.8-inch display, but never the 2.16-inch variant, so let's have a quick look at the hardware first. ESP32-S3-Touch-AMOLED-2.16 specifications: Wireless MCU – Espressif Systems ESP32-S3R8 CPU – Dual-core Tensilica LX7 @ up to 240 MHz with vector instructions for AI acceleration. Memory – 512KB RAM, 8MB PSRAM ROM – 384KB Connectivity – 2.4 GHz WiFi 4 and Bluetooth 5.0 LE Storage 16MB NOR flash MicroSD card slot

SONOFF Hydro DUO – A dual-channel Zigbee 3.0 smart water valve with flow meter

SONOFF Hydro DUO is a dual-channel Zigbee 3.0 and Bluetooth 5 LE smart water valve with up to 12 customized watering schedules, a flow meter, and alerts for frost risk, leakage, low battery, and water shortages. Paisit previously reviewed the SONOFF SWV smart water valve, but the company has now launched the Hydro series with various improvements, including a brass inlet instead of a plastic one, weather-based skipping, real-time alerts, flow metering, and dual Zigbee + BLE so it can work even without a Zigbee gateway. The single-channel Hydro models were introduced earlier this year, and now the Hydro DUO offers a variant with two outlets to manage two watering zones. SONOFF Hydro DUO (SWV-ZF2U/SWV-ZF2E) specifications: MCU -   Telink TLSR8258 (TLSR8258F1KAT32) multiprotocol microcontroller @ 48 MHz with BLE 5 and Zigbee 3.0, RF4CE, Thread, 6LoWPAN, HomeKit, ANT, and 2.4GHz proprietary connectivity Inlets SWV-ZF2U model - NH (National Hose) pipe thread
