Edgeberry allows you to build and manage Raspberry Pi IoT Edge devices

The EdgeBerry is an open-source platform that comprises a base board, hardware cartridges, and software for building Raspberry Pi IoT Edge solutions designed by Belgium-based maker, Sanne Santens. The Edgeberry Base Board is the primary printed circuit board that connects all the other components to the Raspberry Pi. While it is not a HAT (Hardware Attached on Top), it plugs into the GPIO header on the Pi and provides certain interfaces and features that make it easier to use your Raspberry Pi as an IoT Edge device and deploy it in the real world. Unused GPIO pins are exposed on the expansion slot for Edgeberry Hardware Cartridges. Edgeberry Base Board specifications: 40-pin GPIO connector for interfacing with the Raspberry Pi Expansion slot for connecting Edgeberry Hardware Cartridges Misc – Buzzer, Bi-color LED, Button 3A step-down converter 12V DC power jack A unique advantage of the Edgeberry platform is the ability […]

Integrated motor driver and controller bundles ESP32-S3 and TMC2209 for IoT applications

The PD Stepper is a NEMA 17 integrated stepper motor driver and controller board powered by USB power delivery that combines an ESP32-S3 wireless microcontroller, the Trinamic TMC2209 ultra-silent motor driver, and other components onto a single board for Smart Home and automation applications. The maker, Josh R., states that the PD Stepper isn’t another “just because we can” project. It addresses the need for an integrated motor driver and controller module that can used in compact or space-constrained designs. The ESP32-S3 SoC controls the other components on the board and provides wireless connectivity as well as access to development tools and libraries such as ESPHome and ESP-Now. The motor driver IC, Analog Devices’s Trinamic TMC2209, offers efficient, noiseless control of two-phase stepper motors. Other onboard components and connectors include an AS5600 magnetic rotary position sensor, a 3.3V buck converter, a Qwiic/Stemma QT connector, a motor connector, and an AUX […]

ESP8266-powered Netgotchi network security scanner aims to protect your home network

The Netgotchi network security scanner is a simple, compact device based on an ESP8266 wireless microcontroller with a single goal: to defend your home network from intruders and potential bad actors. It is described as “Pwnagotchi’s older brother,” a network guardian that keeps your network safe instead of penetrating it. If you are unfamiliar with Pwnagotchi, it is an A2C-based (advantage actor-critic) “AI” that can penetrate Wi-Fi networks using WPA key material obtained from passive sniffing or de-authentication attacks. The Netgotchi is a reverse Pwnagotchi that alerts you to intruders or breaches in your network. It runs on a simple microcontroller and cannot employ reinforcement learning like the Pwnagotchi. Rather, it pings the network periodically and reports any new potential security threats. The device’s design is as simple as its purpose. It is an ESP8266 microcontroller connected to an OLED display and running an Arduino .ino script, enclosed in a […]

ANAVI Dev Mic is a digital omnidirectional microphone based on Raspberry Pi RP2040 MCU (Crowdfunding)

The ANAVI Dev Mic is an open-source microphone board from ANAVI Technology in Plovdiv, Bulgaria powered by the Seeed Studio XIAO RP2040 module and an omnidirectional digital microphone from STMicroelectronics. It is a compact and affordable product that outperforms USB microphones in artificial intelligence and machine learning voice applications. The design is simple and unassuming, with the Seeed Studio XIAO RP2040 module in the center, surrounded by a USB-C port for power and programming and 9 GPIO pins for extensibility. The STMicroelectronics MP23DB01HP microphone (MK1) is mounted on the top of the board with a small hole on the bottom. It is a compact, low-power, digital MEMS microphone capable of capturing sounds from different directions with very low distortion. It uses a PDM (Pulse-Density Modulation) interface created via the programmable inputs/outputs (PIO) on the RP2040. The ANAVI Dev Mic is applicable for conducting AI/ML research, building a voice recognition platform, […]

Bus Pirate 5XL and 6 hardware debugging tools utilize Raspberry Pi RP2350A and RP2350B microcontrollers

The Bus Pirate 5XL and 6 are open-source hardware debugging tools respectively based on Raspberry Pi RP2350A and RP2350B and designed to simplify interaction with various bus protocols like 1-Wire, I2C, SPI, UART, several LEDs, and more. The idea is to send commands to a chip or sensor and get the response, without writing a single line of code making it ideal for hardware hacking and tinkering. The devices feature buffered I/O pins with voltage and current measurement, a programmable power supply with current limiting, an RGB LCD for pin status and info, and an auxiliary header for connecting logic analyzers. All these features make this device useful for applications like debugging circuits, prototyping projects, and reverse engineering devices. The new devices are updates to the Bus Pirate 5 based on Raspberry Pi RP2040 MCU. You’ll find Bus Pirate specifications for the three models in the table below. The original […]

Mixtile Edge 2 Kit review with Home Assistant, 2-in-1 Zigbee & Z-Wave mPCIe module

We received the Edge 2 Kit IoT gateway on the Rockchip RK3568-powered Edge2 single board computer (SBC) and a 2-in-1 Zigbee and Z-Wave mPCIe card from Mixtile which we will be reviewing from the perspective of smart home applications using Home Assistant open-source home automation framework. Let’s dive into the details. Unboxing Mixtile Edge 2 Kit CNX Software previously reported on the Mixtile Edge 2 Kit in 2022 and you can check the detailed specifications and block diagram in that earlier article. Since then, Mixtile has found a wider range of applications for the device and is also promoting it as an Edge AI Box that performs AI object detection using the Edge 2 Kit (or the more powerful Mixtile Blade 3) using the built-in NPU (Neural Processing Unit) with up to 1 TOPS of AI performance for tasks such as object detection. Let’s unbox it and take a closer […]

Linamp – A Raspberry Pi 4-based audio box with Winamp look and feel

Linamp is a media player box based on Raspberry Pi 4 SBC and a touchscreen display with a GUI that replicates the popular Winamp media player’s GUI that older readers may remember from the late 90s and early 2000s when it was one of the most popular music players for Windows. Rodmg found some renders of what a real Winamp player could look like online, and it inspired him to create his own. As its name implies Linamp runs on Linux (DietPi) instead of Windows, and the hardware is based on a Raspberry Pi 4, a 7.9-inch touchscreen display, a USB DAC, and various connectors and cables, all housed in a custom-designed metal enclosure and a 3D-printed front cover both designed with Onshape. Here’s the complete list of off-the-shelf items used for the build: SBC – Raspberry Pi 4 with a 32 GB microSD card, a set of passive heat […]
