M5Stack M5PoECAM-W V1.1 – A ESP32-powered PoE camera module with 3MP OV3660 sensor

M5Stack M5PoECAM-W V1.1 is a PoE camera module built around the Espressif ESP32 MCU and WIZnet W5500 Hardwired TCP/IP embedded Ethernet controller. The W5500 along with a PoE controller takes care of ethernet and PoE power whereas the 3MP OV3660 sensor is responsible for video and photos. The camera features a wide 65° field of view which makes it suitable for applications like image monitoring and remote data acquisition. Previously we have covered similar camera modules like the LILYGO T-Camera-Plus-S3, Sipeed MaixCAM, and Luxonis OAK-D Series 2 cameras with the latter also having a PoE option. Feel free to check those out if you are interested in the topic.

ESP32-S3-based kit allows you to build an Internet Radio with a touchscreen display

The ESP32 Internet Radio from Poland-based maker, The MicroMaker, is a simple hardware kit that combines the LilyGo T-Display S3 Development board with an I2S audio breakout module and other components to form a radio that can access and stream from online radio stations. With the ESP32 Internet Radio, you are not limited to the radio stations available in your immediate vicinity. It is powered by the LilyGo T-Display S3 which integrates the network-capable ESP32-S3 microcontroller (Wi-Fi + BLE 5), a 1.9” full-color capacitive touchscreen display, and two programmable buttons. The ESP32-S3’s integrated Wi-Fi capability allows the radio to connect to the Internet, and the touchscreen brings an intuitive and easy-to-use interface to the device. It supports up to 512 stored radio stations, and you can manage these stations from a web browser on your PC or mobile phone. The Internet Radio can be powered by an 18650 Lithium-ion battery […]

Serial Bus Servo Driver HAT (A) can drive up to 253 servos simultaneously

Waveshare has recently introduced the Serial Bus Servo Driver HAT (A) ESP32-powered servo motor controller for the Raspberry Pi designed to drive up to 253 serial servos simultaneously. The servos can be controlled via UART or USB through the Pi SBC or used as a standalone controller for a robotics project. The board has a wide input voltage range of 9 to 25 volts and features an onboard XT60 connector, a screw terminal, and a DC barrel jack any of which can be used as power input. Besides that, the board features an RS485 port a TTL Servo header, and a UART control switch for convenience. Previously we have written about the Suptronics X200 HAT multifunction expansion board for the Pi with servo support, as well as the ELECFREAKS Wukong 2040 which can also be used to drive servos.

Apple’s Embedded Swift programming language supports ESP32-C6, Raspberry Pi RP2040, STM32F7, nRF52840 microcontrollers

Apple has released a beta version of Embedded Swift that notably works with Espressif ESP32-C6 wireless RISC-V microcontroller, and the company also built a Matter sample based on ESP-IDF and ESP-Matter SDKs. Embedded Swift is not limited to the ESP32-C6 and supports other microcontrollers from STMicro, Raspberry Pi, Nordic Semi, etc… Apple Swift programming language is mostly designed for mobile app development, but we’ve also seen it being used on Mad Machine’s SwiftIO board powered by a 600 MHz NXP i.MX RT1052 Arm Cortex-M7 crossover processor and the tiny SwiftIO Micro launched a few years later. The company has now decided to create a subset of the Swift programming language better suited to microcontrollers simply called Embedded Swift that’s currently working on STMicro STM32F746, Raspberry Pi Pico, nRF52840, and ESP32-C6. The “Go small with Embedded Swift” presentation at WWDC 2024 shows how to get started with Embedded Swift using Espressif […]

ThingPulse Pendrive S3 ESP32-S3 USB stick comes with 128MB of storage and a capacitive spring button

ThingPulse ESP32-S3 Pendrive spring button

The Pendrive S3 is an ESP32-S3 development board in a USB stick enclosure with 128MB of flash memory and an unusual capacitive touch button. The Espressif ESP32-S3-MINI-1 module on the board integrates an Xtensa dual-core 32-bit LX7 microprocessor with support for 2.4GHz Wi-Fi and Bluetooth 5 (low-energy). The device features a capacitive touch button that can be used to trigger actions by touching the enclosure. The capacitive button isn’t visible on the exterior of the device, which helps the device maintain a low profile. You may be interested in Dani Eichhorn’s article on how he came up with the idea of using a spring for the capacitive touch button. The Pendrive S3 stick can be used as a BadUSB device for hacking and penetration testing purposes. With the aid of SuperWiFiDuck, it can perform keystroke injection attacks. All scripts can be managed and controlled wirelessly via a web interface, and […]
