ESP32-P4 development board

Espressif Systems “ESP32-P4-Function-EV-Board” – the official ESP32-P4 development board – is now available in limited quantities on Espressif’s AliExpress store for $55.44, and some other AliExpress stores at a premium as part of a kit with a 7-inch touchscreen display and a 2MP camera module. First unveiled in January 2023, the ESP32-P4 is the first general-purpose RISC-V microcontroller from Espressif Systems without any wireless connectivity. It’s a high-end microcontroller with two RISC-V cores clocked at 400 MHz, vector instructions for AI acceleration, a 2D graphics accelerator for smooth graphical user interfaces, and H.264 video encoding support. There’s been some buzz about it in recent months, and finally, it’s now possible to purchase an ESP32-P4 board for evaluation and software development. ESP32-P4-Function-EV-Board development board specifications: Microcontroller – Espressif Systems ESP32-P4 CPU Dual-core RISC-V HP (High-performance) CPU @ up to 400 MHz with AI instructions extension and single-precision FPU, 768KB of on-chip […]

Makerfabs SenseLora 4G gateway supports LTE Cat 1 and WiFi 4 connectivity, features solar battery charger

SenseLoRa 4G LTE CAT1 Gateway

The Makerfabs SenseLora 4G Gateway is a device that collects data from LoRa sensors (like temperature and humidity sensors) and sends that data over a 4G network to a cloud service or directly to your phone via SMS, this is ideal for applications where installing a LoRaWAN device is unnecessary or expensive. The application for this gateway includes monitoring soil humidity in your backyard or greenhouse conditions on your farm. Previously we have written about similar smart agriculture sensors including AgroSense LoRaWAN sensors and WisGate Soho Pro RAK7267 LoRaWAN gateway feel free to check those out if you are looking for LoRa-based agricultural products. Makerfabs SenseLora 4G gateway 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 – WiFi 4 and Bluetooth 5.0 LE + Mesh connectivity LPWAN connectivity LoRaWAN SX1276 LoRa module Frequencies 868 […]

Waveshare ESP32-S3-Zero is a tiny WiFi and BLE IoT module with a USB-C port, up to 32 GPIOs

ESP32-S3-Zero

Waveshare ESP32-S3-Zero is a tiny (23.5×18 mm) module based on Espressif ESP32-S3 WiFi 4 and BLE microcontroller with two rows of nine through holes plus 16 pads for GPIOs, a USB-C port for power and programming, Boot and Reset buttons, and a ceramic antenna. It reminds me of the Seeed Studio’s XIAO ESP32S3 module with an even smaller 21 x 17.5mm design, but the ESP32-S3-Zero offers more GPIOs, an RGB LED, and a built-in ceramic antenna instead of a u.FL connector for an external antenna. Waveshare ESP32-S3-Zero specifications: Wireless MCU – Espressif Systems ESP32-FH4R2 CPU – dual-core Tensilica LX7 microcontroller @ 240 MHz Memory – 512KB SRAM,  2MB PSRAM Storage – 4MB flash Wireless – Wi-Fi 4 & Bluetooth 5.0 dual-mode (classic + BLE) connectivity Antenna – 2.4 GHz ceramic antenna USB – USB Type-C port for power and programming Expansion I/Os 2x 9-pin 2.54mm pitch headers and castellated holes […]

Arduino and LVGL-compatible ESP32-C3 board features a 1.28-inch round touchscreen display fully housed in a case

ESP32-2424S012 round display full enclosure

The ESP32-2424S012 is an ESP32-C3 WiFi and BLE development board with a 1.28-inch round touchscreen color display that is fully housed in a black or white plastic enclosure and suitable for Arduino and LVGL library. As we’ll see further below some have also used it with Tasmota and ESPHome firmware. We previously covered several tiny ESP32-S3/ESP32-C3 boards with a round display such as the LILYGO T-RGB ESP32-S3 board, Makerfabs “ESP32-S3 Round SPI TFT with Touch 1.28″, SB Components’ Dual Roundy, but they either don’t come with a case at all, or only the front is covered, but the bottom is laid bare. The ESP32-2424S012 is quite similar, but it can be purchased with a case that covers both the front and back with some openings for expansion connectors. ESP32-2424S012 board specifications: Wireless module – Espressif Systems ESP32-C3-MINI-1U module SoC – ESP32-C3 RISC-V microcontroller @ 160 MHz with 400 KB SRAM, 2.4 […]

The Open Home Foundation adds HACS, microWakeWord, and Music Assistant open-source projects

Open Home Foundation adds HACS, microWakeWord, Music Assistant

HACS, microWakeWord, and Music Assistant projects have joined the Open Home Foundation launched a few months ago to manage open-source projects related to Home Assistant and Smart Home applications in general separating them from Nabu Casa’s commercial activities. Note the HACS, microWakeWord, and Music Assistant projects will not operate directly under the Open Home Foundation’s umbrella, but they are external projects that the foundation collaborates on since it believes those are projects worth investing in to further develop the Smart Home ecosystem. Let’s have a quick look at the three projects. Home Assistant Community Store (HACS) is the most used custom integration for Home Assistant and allows users to easily install custom integrations, cards, and themes. Music Assistant gives users control over their media players and audio files handling both local music collection and music streaming services so that users can play any tune anywhere in their house without restrictions.
