Makerfabs MaUWB for Home Assistant – An ESP32-S3 UWB module with PoE and enclosure

MaUWB for Home Assistant

Makerfabs MaUWB for Home Assistant is an ESP32-S3-based Ultra-Wideband (UWB) module designed for indoor positioning and Real-Time Location Systems (RTLS). It runs ESPHome for Home Assistant integration, enabling it to be used as part of a UWB-based positioning system to track tagged devices in homes, offices, and other indoor environments. The module combines an ESP32-S3 with a MaUWB UWB module based on the Qorvo DW3000, featuring a PA/LNA for long-range ranging. Compared to the earlier ESP32-S3 version, it drops the OLED and adds a WIZnet W5500 Ethernet controller that supports PoE. The module also supports Wi-Fi 4 and Bluetooth 5.0, and comes in an enclosure for fixed installations. Makerfabs MaUWB for Home Assistant specifications: Wireless Module – ESP32-S3-WROOM-1 SoC – Espressif Systems ESP32-S3 CPU – Dual-core Tensilica LX7 up to 240 MHz with vector extension for AI/ML workloads RAM – 512KB SRAM; 8MB PSRAM Wireless – WiFi 4 and Bluetooth LE 5 […]

ESP32-C5 devkit offers 2.8-inch capacitive touch display, dual-band Wi-Fi 6, Bluetooth 5 LE, LiPo battery support

ESP32-C5-Touch-LCD-2.8

Last week, I wrote about the ESP32-C5-LCD-1.47 as one of the first ESP32-C5 devkits with a built-in display enabling dual-band WiFi 6 connectivity for IoT and HMI projects. However, one reader lamented the lack of touch-capable screens, at which point kwchow pointed to the ESP32-C5-Touch-LCD-2.8 model offering just that by pairing an ESP32-C5 with a 2.8-inch IPS  display with capacitive touch and 320×480 resolution. The new board also features a microSD card slot, a USB-C port for power and programming, a built-in microphone and a speaker connector, a few sensors, and various I/Os connectors for expansion. Let’s have a closer look. ESP32-C5-Touch-LCD-2.8 specifications: Wireless module – Espressif Systems ESP32-C5-WROOM-1-N32R8 SoC – ESP32-C5HR8 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 power-sensitive applications Memory – 384 KB SRAM on-chip, 8MB PSRAM Storage – 320 KB ROM Wireless […]

ESP32-C5 dual-band WiFi 6 and Bluetooth LE IoT board features 1.47-inch color LCD

ESP32-C5-LCD-1.47 board

We’ve covered plenty of connected displays based on ESP32 chips over the years, but the Waveshare ESP32-C5-LCD-1.47 is a little different, since it’s the first to feature an ESP32-C5 chip for dual-band WiFi 6 connectivity. It’s basically based on the ESP32-C6-LCD-1.47 design, but replaces the ESP32-C6 supporting 2.4 GHz WiFi 6 with an ESP32-C5 capable of handling both 2.4 GHz and 5 GHz WiFi 6. Other features mostly remain the same: a 1.47-inch 262K-color display with 320 x 172 resolution, 4MB of flash, an RGB LED, a microSD card slot, and two 9-pin headers for GPIO expansion. Waveshare ESP32-C5-LCD-1.47 specifications: Wireless MCU – Espressif Systems ESP32-C5FH4 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 power-sensitive applications Memory – 384 KB SRAM on-chip Storage – 320 KB ROM, 4MB flash Wireless Connectivity Dual-band (2.4GHz/5 GHz) 802.11ax WiFi […]

Arduino launches Modulino Hub and Extender modules to support up to 64 I2C devices, 30-meter range

Arduino Modulino Hub Extender I2C modules

Arduino has just introduced three new Modulino modules: the Modulino Hub to support up to eight I2C devices (64 devices with 8 Hubs), the Modulino Extender to extend the I2C range to up to 30 meters, and the Modulino Motors to control two DC motors or a single stepper motor with precision. I’ll focus on the I2C modules in this post, as I find the Modulino Extender module particularly interesting, since I always considered I2C to be a short-range communication protocol, and never thought of using it for (relatively) long-range wired communication. Modulino Hub While the I2C protocol supports up to 127 devices in theory, address conflicts can become an issue in complex builds where multiple sensors or actuators share the same default address. The Modulino Hub aims to solve that, and multiple Hubs can be daisy-chained, each with its own address, to support up to 64 devices. Modulino Hub specifications: […]

MaTouch ESP32 P4 TFTTouch 10.1 inch MIPI with 4G LTE SIM7670G

Makerfabs MaTouch ESP32-P4 TFTTouch 10.1 MIPI with 4G LTE is an ESP32-P4 + ESP32-C6-based display development platform for HMI edge AI, and connected embedded applications. The development board features a 10.1-inch IPS LCD, very similar to those of Seeed Studio’s reTerminal D1001, Waveshare ESP32-P4-WIFI6-Touch-LCD, and CrowPanel Advanced 7-inch displays. However, what makes it unique compared to other devices is that it also features a SIM7670G 4G LTE modem with a SIM card slot, an RJ45 Ethernet jack, and a 2MP camera. The HMI display also comes with microphone and speaker connectors, a microSD card slot, various USB interfaces, lithium battery support, and two 2.54 mm pitch GPIO expansion headers exposing UART, I2C, SPI, and other peripheral interfaces. All these features make it suitable for HMI, edge AI, and connected embedded applications.

ST VL53L9CX direct Time-of-Flight 3D LiDAR supports 5cm to 9m range, 2.3K zones resolution

ST VL53L9CX direct Time-of-Flight 3D LiDAR

STMicroelectronics VL53L9CX, or VL53L9 for short, is the company’s first direct Time-of-Flight (dToF) 3D LiDAR all-in-one module. It offers a sensing range of  5 centimeters to 9 meters, a wide 72º field of view, a resolution of 2.3K zones, and up to 100 Hz frame rate. ST’s ToF sensors have gone a long way since we covered the VL53L0X sensor with a single zone and 2-meter range in 2017. Since then, the company has steadily improved its tiny ToF sensors with up to 64 zones and long range in recent sensors like the VL53L8CP. While the VL53L9CX is still tiny at 12.8 x 6.1 x 4.6 mm, it’s in a class of its own, acting like a mini 3D scanner with 2268 zones, and will be used for a range of applications in robotics, industrial automation, smart buildings, AR/VR, and healthcare.
