ESP32-S3-PICO-based OMGS3 is the world’s smallest fully-featured ESP32-S3 module/board

Based on the ESP32-S3-PICO system-in-package (SiP), Unexpected Maker OMGS3 is a small, yet full-featured ESP32-S3 module/board whose designer claims is the world’s smallest in its category at just 25x10mm in size. It replaces the earlier Unexpected Maker NanoS3 based on the ESP32-S3FN8 SoC measuring 28 x 11 mm. The OMGS3’s ESP32-S3-PICO SiP integrates a dual-core ESP32-S3 WiFi and BLE wireless SoC, 8MB QSPI flash, and 2MB QSPI PSRAM. The board itself also includes a 3D antenna, an RGB LED, two LEDs for power and charging, and I/Os are exposed through 26 solder pads. Unexpected Maker OMGS3 specifications: SiP – Espressif ESP32-S3-PICO SoC ESP32-S3 dual-core Tensilica LX7 up to 240 MHz with 512KB SRAM, 16 KB RTC SRAM Wireless – WiFi 4 and Bluetooth 5 LE + Mesh Memory – 2MB QSPI PSRAM Storage – 8MB QSPI flash Antenna – High-gain 3D antenna I/Os via 26x solder pads Up to 17x GPIO […]

The Epi C3 is a tiny ESP32-C3 development board with USB-C and an onboard antenna

The Epi C3 is a small development board based on the Espressif ESP32-C3 microcontroller with a USB-C connector for power and programming and an onboard ceramic antenna for wireless applications. We have previously covered several tiny ESP32-C3 development boards such as the Microflex series, ESP32-C3-0.42LCD, the XIAO ESP32C3, and LOLIN’s C3 Mini and C3 Pico. The Epi C3 claims the title of the “smallest ESP32 dev board with USB-C and an onboard antenna.” It uses a Johanson ceramic antenna with a “surprising range for its size” and the USB-C port is sunk into the board to reduce footprint. The ESP32-C3 microcontroller on the Epi C3 board is much more powerful than the 8-bit AVR chip on its predecessor, the Epi 32U4. The Epi C3, however, retains many of the older board’s protective features, including TVS diodes on the USB data lines and power input, a 500mA on the USB power […]

nRFBOX V2 ESP32 wireless hacking tool can scan, analyze, spoof, and jam the whole 2.4GHz spectrum

CiferTech has recently introduced the nRFBOX V2 ESP32-based wireless hacking tool designed for spectrum analysis, jamming, BLE device emulation, and more. The device is built around an ESP32-WROOM-32U module and includes an NRF24 module covering the whole 2.4GHz spectrum. Additionally, the device has a 0.96-inch OLED display, a five-way microswitch control pad, and a WS2812 RGB LED for feedback. The device can also be operated with a single 3.7V lithium battery, and that batter’s charging is handled by a TP4056 charging IC. All these features make this device useful for wireless security testing, educational environments, research, and hobbyist projects. Previously we have written about similar portable hacking tools like the DSTIKE Deauther Watch X, the HackBat pen-testing device, and the popular Flipper Zero wireless hacking tool. Feel free to check those out if you are looking for similar products. nRFBOX V2 specifications Microcontroller – ESP32-WROOM-32U with ESP32 dual-core wireless microcontroller […]

Arduino CLI 1.0 released – Let’s try it with the Raspberry Pi Pico 2

Arduino has just announced the release of the Arduino CLI version 1.0.0, the first stable release for which users and developers can be confident the software API won’t change over time, or at least with minimal changes that will not impact the workflow of applications based on it. We first looked at the Arduino CLI when it was still at the alpha stage way back in 2018. Arduino CLI version 1.0.0 was actually quietly released about two months ago, but Arduino only announced it now and the utility is now at version 1.0.4 with several bug fixes. Arduino CLI 1.0 release The goal of the API is to easily program the boards from the command line without having to use the Arduino IDE, and the CLI can be integrated into your own script to automatize various processes. Arduino explains there are three ways to integrate and utilize the capabilities of […]

ESP32-S3 USB dongle integrates 1.47-inch TFT LCD display

Waveshare ESP32-S3-LCD-1.47 is an ESP32-S3 USB dongle with Wi-Fi, Bluetooth, high-capacity Flash and PSRAM, and a 1.47-inch LCD. Additionally, it has an onboard microSD card slot used for storage and some RGB LEDs for visual feedback. All these features make this tiny device suitable for applications like interactive displays, IoT devices, hardware pentesting, and more. Previously we have written about the LILYGO T-HMI a similar ESP32-S3-based development board built for HMI applications, as well as the ESP32-S3-Touch-LCD-4.3B and Waveshare ESP32-S3 LCD Driver Board, but it must be the first time we’ve come across a USB dongle-like ESP32-S3 board with an integrated display. ESP32-S3-LCD-1.47 specifications: Wireless MCU – Espressif Systems ESP32-S3R8 CPU – Dual-core Tensilica LX7 @ up to 240 MHz with vector instructions for AI acceleration. Memory – 512KB RAM, 8MB PSRAM Storage – 384KB ROM Connectivity – 2.4 GHz WiFi 4 and Bluetooth 5.0 LE with support for long-range, up […]

WeAct RA4M1 – A small board with plenty of GPIOs that’s software-compatible with the Arduino UNO R4

Last week, we covered the Maker Go RA4M1-R4 development board, an inexpensive “clone” of the Arduino UNO R4 Minima with some small modifications like support for up to 50V DC input and a 3.3V/5V switch for I/Os. But today, I’ve come across a smaller and cheaper Renesas RA4M1 board that’s also software compatible with the Arduino UNO R4. Meet the WeAct RA4M1. The WeAct RA4M1 is mostly a breakout board for the Renesas R7FA4M1AB3CFM Arm Cortex-M4F microcontroller with two 30-pin GPIO headers, a USB-C port for power and programming, and three buttons. It offers a middle ground between the Arduino UNO R4 Minima and the tiny XIAO RA4M1 USB-C board. WeAct RA4M1 specifications: Microcontroller – Renesas RA4M1 Arm Cortex-M4F MCU @ 48 MHz with 32KB SRAM, 256KB flash USB – 1x USB Type-C port for power and programming Expansion 2x 30-pin headers with GPIO, VIN, VCC, GND 3.3V or 5V […]

LILYGO T-Deck Plus – A Blackberry-like ESP32-S3 devkit with QWERTY keyboard, trackball, LoRa, GPS, battery, and more

LILYGO T Deck Plus handheld development board

The LILYGO T-Deck Plus is an ESP32-S3 based handheld development kit that resembles a Blackberry phone with a QWERTY keyboard and trackball. The device features a 2.8-inch IPS LCD, a GPS module, a LoRa transceiver, and a 2,000mAh battery which means you can take it outside and do some pen-testing and research. Additionally, the board features a microphone, a speaker, and a microSD card slot for storage. Just last year, LILYGO introduced the LILYGO T-Deck ESP32-S3 development board with LoRa and a 2.8-inch display, and the T-Deck Plus builds on the earlier design but also adds a GPS module and a higher capacity battery. LILYGO T-Deck Plus specifications ESP32-S3-WROOM-1 wireless module SoC – ESP32-S3FN16R8 dual-core Tensilica LX7 microcontroller @ up to 240 MHz with 2.4 GHz 802.11n WiFi 4 and Bluetooth 5.0 LE connectivity Memory – 8MB PSRAM Storage – 16MB SPI flash PCB antenna Storage – MicroSD card slot Display – […]

Maker Go RA4M1-R4 core board is a cheap Arduino UNO R4 Minima clone taking up to 50V DC input

The Maker Go RA4M1-R4 core board is another Arduino UNO R4 Minima clone but offered at a price point much lower than the original and the Waveshare R7FA4 Plus A (another clone) since it shows up for only $0.99 on AliExpress with free shipping. Note that the ultra-low price is because of a “Welcome deal” on AliExpress, and the regular price is $7.76, so not everyone may get it for $1. About $8 is still cheap compared to the $20 (18 Euros) asked for the official Arduino UNO R4 Minima board. Let’s look at the clone in more detail to find out if they’ve made any changes to the board. Maker Go RA4M1-R4 core board specifications: Microcontroller – Renesas RA4M1 Arm Cortex-M4F MCU @ 48 MHz with 32KB SRAM, 256KB flash USB – 1 x USB Type-C port for power and programming Expansions – Arduino UNO female + male headers […]
