T-Display-P4 smartphone-like devkit features ESP32-P4 MCU, ESP32-C6 wireless SoC, and SX1262/LR2021 LoRa transceiver
LILYGO T-Display-P4 is a feature-rich ESP32-P4 + ESP32-C6 devkit, but with a smartphone-like design and support for GPS, Ethernet, and LoRaWAN through SX1262 or LR2021 LoRa transceiver, besides the usual WiFi 6, Bluetooth 5.x, and 802.15.4 wireless connectivity. The T-Display-P4 is offered with either a 4.05-inch IPS display and a 2MP front-facing camera or a 4.1-inch AMOLED with a 2MP rear camera. The devkit is equipped with 32MB PSRAM and 16MB NOR flash for the ESP32-P4, a microSD card slot, a built-in microphone and speaker, a 3.5mm audio jack, a few USB ports, and a 9-axis motion sensor, as well as a GPIO port and two Qwiic connectors for expansion. T-Display-P4 specifications: MCU - ESP32-P4 CPU Dual-core RISC-V microcontroller @ 360 MHz with AI instructions extension and single-precision FPU Single-RISC-V LP (Low-power) MCU core @ up to 40 MHz GPU – 2D Pixel Processing Accelerator (PPA) VPU – H.264 and
Finally found a MOSFET with a small footprint and a low price that seems to be able to easily handle PWM for 12V/6W dimmable LED spots when driven by only 3.3V logic level: AOD424.
I use NRF52840 dev boards, as they have a minuscule power consumption of less than 15mA at 3.3V even with Bluetooth on and discoverable. Sure, not much of a difference when the lights are on; but when the lights are off, and you throw 20 of those onto your offgrid net, it suddenly matters!
Снимаем показания счётчика электроэнергии МИР С-05.10 c помощью Raspberry по Bluetooth
Из любопытства была у меня идея попробовать снять показания со счётчика удалённо, но так как был уже установлен древний дубовый счётчик Энергомера СЕ102, то вкладываться в замену не хотелось. Однако межповерочный интервал начал подходить к концу и я начал задумываться насчёт замены счётчика на более продвинутый (с интерфейсами связи). Начал выбирать варианты в виде LoRaWan, Zigbee, RS-485, но оказалось, что по современному законодательству счётчики электроэнергии меняет ресурсоснабжающая организация (так называемый "гарантирующий поставщик"). С надеждой ждал, что электрик придёт и поставит современный навороченный счётчик с кучей интерфейсов, но всё оказалось не совсем так... Представитель ресурсоснабжающей организации установил новый счётчик МИР С-05.10-230-5(80)-G2Z1B-KNQ-S-D.
M5Stack Stamp-P4 – A tiny ESP32-P4 USB-C board with optional Wi-Fi 6 and Bluetooth 5.4
M5Stack has just introduced the Stamp-P4, a tiny USB-C development board built around the ESP32-P4 high-performance RISC-V MCU chip, featuring 16MB of Flash and 32MB of PSRAM, and optional Wi-Fi 6 and Bluetooth 5.4 support through the ESP32-C6-MINI-1-based Stamp-AddOn C6 module.

Reverse Engineering or Necromancy? 🧟♂️⚖️
What do you do when the company goes dark, the app vanishes from the App Store, and your "smart" scale becomes a 100€ paperweight?
You reverse it.
I’m starting a new series on ByteArchitect about bringing the QardioBase2 back to life. No ChatGPT-farts here—just raw bluetoothd logs, GATT discovery, and the sad sight of a backend that keeps saying "cancelled."
In this first part:
- Sniffing BLE traffic on iOS (without a jailbreak)
- Mapping proprietary GATT services & characteristics
- Realizing the servers are officially dead (RIP Qardio)
If you despise planned obsolescence as much as I do, join me in this "zombie" recovery:

Hi Karl, why don't you try asking that amazonian what a Thomas Guide is❓
