ESP32 Marauder 5G – Apex 5 module for Flipper Zero combines ESP32-C5, two Sub-GHz radios, nRF24, and GPS

Designed by HoneyHoneyTrading, the ESP32 Marauder 5G – Apex 5 Module is an ESP32-C5-based hacking and penetration testing tool for the Flipper Zero, with dual-band WiFi 6 (2.4GHz and 5GHz), two Sub-GHz radios (868MHz and 433MHz), an NRF24 radio, and a built-in GPS. This new Flipper Zero module can be considered an upgrade from the ESP32 Marauder – Double Barrel 5G, as it does not rely on a dual-chip configuration for 5 GHz operation, leveraging the ESP32-C5 dual-band capabilities instead. A microSD card slot handles storage, and the device can also save data directly to the Flipper Zero’s microSD card. It also features five antennas, including WiFi, Sub-GHz, nRF24, and GPS, along with dedicated LED indicators for the Sub-GHz radios and nRF24 activity. There is also a hardware button to toggle 433 MHz and 868 MHz Sub-GHz operation, a USB-C port, and a side button for power management and firmware […]

Add a tiny desktop monitor to your PC with the ESP32 Desktop Monitor project

While searching AliExpress for new products, I found the TENSTAR T-Display ESP32-D0WD with a 1.14-inch IPS color IPS LCD and 16MB of QSPI flash that’s used by some as a tiny secondary mirrored monitor for their PC. The board appears to be a low-cost alternative to the original LilyGo T-Display, and also integrates a USB-to-TTL converter (CH9102F), a battery charging circuit, a toggle switch, and two user-programmable buttons, which makes it suitable for projects like the NerdMiner and small-scale dashboards for home automation. The hardware does not seem special, yet they sold over 10,000 pieces of the board. After looking into it, the ESP32 Desktop Monitor project is probably the “culprit” for the high sales number, as it transforms the board into a regular monitor, albeit with a tiny 1.14-inch LCD. More on that after the specifications. TENSTAR T-Display Specifications: SoC – Espressif Systems ESP32-D0WDQ6-V3 MCU cores – Dual-core Xtensa LX6 32-bit […]

Review of XIAO ePaper DIY Kit EE02 13.3-inch color E-Ink display with SenseCraft HMI and Arduino

Seeed Studio has sent us a sample of the XIAO ePaper DIY Kit EE02 for review. The kit is comprised of an ESP32-S3 board driving a 13.3-inch Spectra 6 color E-Ink display with 1600 x 1200 resolution. It supports Wi-Fi and Bluetooth 5.0 (LE) wireless connectivity, and features a USB Type-C port for power and programming, a battery connector with an on/off power switch, a built-in charging circuit, a Reset button, and three user buttons. In this review, we will test the XIAO ePaper DIY Kit EE02 with the SenseCraft HMI platform and the Arduino IDE. But first, let’s go through an unboxing. XIAO ePaper DIY KIT EE02 unboxing We received the XIAO ePaper DIY Kit EE02 in a cardboard box with foam to protect the display. The package includes the 13.-inch ePaper display, the XIAO ePaper Display EE02 board, an external antenna, and a set of two 60-pin adapters […]

PicoIDE – An open-source hardware IDE/ATAPI drive emulator for vintage computers (Crowdfunding)

PicoIDE is an open-source hardware IDE/ATAPI drive emulator based on a Raspberry Pi RP2350 board and designed to replace hard drives and CD-ROM drives in vintage computers with microSD card storage. Users don’t need to burn optical discs or deal with old IDE hard drives with bad blocks, and instead, they can simply put their disk images on a microSD card and swap between them as needed. Two versions are offered, namely the PicoIDE Base featuring full IDE/ATAPI emulation in a standard 3.5-inch enclosure with a microSD card slot, and CD audio output, and the PicoIDE Deluxe, adding an ESP32-C3-based front panel with WiFi connectivity, an OLED, and navigation buttons. PicoIDE specifications: MCU – Raspberry Pi RP2350 microcontroller CPU 2x Arm Cortex-M33 cores @ 150 MHz 2x Hazard3 RISC-V cores @ 150 MHz Up to two cores can be used at any time (configured at boot) Memory – 520KB SRAM […]

DSTIKE AI Home Security Sidekick – ESP32-S3 hacking tool with Wi-Fi, display, camera, and voice interaction

DSTIKE AI Home Security Sidekick, nicknamed “Eve,” is an ESP32-S3-based AI-powered hacking tool with a display, camera, audio interaction, USB, and a built-in battery for portable use. The device is designed by Travis Lin, well known for his deauther watches like the Deauther Watch V4S and the Deauther Watch X, but now they have designed a Home Security Sidekick with a 2.0-inch LCD, a 2MP camera for basic computer-vision tasks, and an onboard microphone and speaker for voice interaction. It supports real-time Wi-Fi deauthentication attack detection through 802.11 management frame analysis, includes a USB Type-C port for charging and firmware flashing, and integrates a physical wake/function button, all housed in a transparent acrylic enclosure for home network monitoring, desktop diagnostics, and educational applications. DSTIKE AI Home Security Sidekick specifications Core module – Espressif Systems ESP32-S3-WROOM-1-N16R8 SoC – ESP32-S3 CPU – Dual-core LX7 processor with up to 240MHz Memory – 512KB SRAM, […]

MicroPythonOS graphical operating system delivers Android-like user experience on microcontrollers

Yesterday, I wrote about Ariel OS RTOS for microcontrollers written in Rust, but there’s another interesting open-source operating system for microcontrollers that will be covered at FOSDEM 2026: MicroPythonOS. While Ariel OS is designed for secure, memory-safe, networked IoT applications on microcontrollers, MicroPythonOS targets applications with graphical user interfaces and is heavily inspired by Android and iOS, with an appstore, an LVGL-based touchscreen and button UI with plenty of widgets, gestures and theme support, and a wifi manager, as well as over-the-air (OTA) firmware updates. You’ll probably be astonished to learn that MicroPythonOS is written in… MicroPython. It’s comprised of a Thin OS which handles hardware initialization, multitasking, and UI, and everything else is an app, including system features like WiFi configuration and OS updates. MicroPythonOS highlights: Native MicroPython foundation Runs on ESP32 microcontrollers, but the FOSDEM 2026 talk mentions that it can run on anything that supports MicroPython, including […]

Ariel OS – A Rust RTOS for IoT microcontrollers

Ariel OS is a new RTOS for microcontrollers written in Rust with support for popular hardware architectures (Arm Cortex-M, ESP32, RISC-V) and boards from Espressif, Nordic Semi, Raspberry Pi, and STMicroelectronics. Ariel OS is built on top of Embassy Rust framework and embedded-hal Hardware Abstraction Layer (HAL) for embedded systems, and adds several OS functionalities and a multi-core capable scheduler. It is mainly designed for secure, memory-safe, networked applications on microcontrollers. The developers further describe Ariel OS as follows on the project’s website: Ariel OS follows an approach whereby it simultaneously integrates a curated ecosystem of libraries (available via crates.io), and adds missing operating system functionalities as depicted below. Such functionalities include a preemptive multicore scheduler, portable peripheral APIs, additional network security facilities, as well as a meta-build system to bind it all together. As a result, a low-power IoT developer can focus on business logic sitting on top of […]
