UniHiker review – A Linux-based STEM education platform with IoT and AI support, Micro:bit edge connector

UniHiker Review

DFRobot’s UniHiker is a STEM educational platform that was originally launched in China, but now UniHiker is now available worldwide through the DFRobot shop. The company has sent us a UniHiker sample for review, so let’s unpack the kit and learn how to use the UniHiker platform. The main component of the kit is the Linux-powered UniHiker board which features a 2.8-inch resistive touchscreen display and a BBC Micro:bit edge connector, so we can use expansion boards for the Micro:bit board. Let’s start unboxing it together. UniHiker unboxing DFRobot sent us the UniHiker platform by DHL. The package is a familiar-looking DFRobot box in orange color and comes with a plastic box to safely store the UniHiker board and accessories after use. The plastic box contains another plastic box with the board, some 3-pin and 4-pin cables for Gravity ports, and a USB Type-C cable. The UniHiker is like a […]

The Bee Data Logger ESP32-S3 board comes with RTC, microSD slot, and two Qwiic connectors for sensors

ESP32 Data Logger

A few months ago, SparkFun released the “Datalogger IoT – 9DoF” no-code platform based on ESP32 with some built-in sensors, a microSD card, and two Qwiic connectors to add sensors in order to perform data logging with minimal to no coding. Smart Bee Designs looks to have shrunk the design, removing the built-in sensors in the processor, with the Bee data logger ESP32-S3 board that offers most of the same features plus a built-in DS3231 RTC and back battery for timekeeping, and the ability to leverage the vector extension in the ESP32-S3 for machine learning applications. Bee data logger specifications: Wireless module – Espressif Systems ESP32-S3-MINI-1 module CPU – ESP32-S3 dual-core Xtensa LX7 microcontroller with vector extensions with 512KB SRAM, 384KB ROM, WiFi 4 and Bluetooth 5.0 connectivity Storage – 8MB of QSPI flash PCB antenna Storage – MicroSD card slot up to 16GB capacity USB – 1x USB Type-C port […]

Diabolic Drive is a penetration testing USB key with 64GB storage, ESP8266 and ATmega32U4 microcontrollers

Diabolic Drive

Diabolic Drive may look like a 64GB USB flash drive and show as such when you insert it into your computer, but it’s actually a wireless keystroke injection tool with a Microchip ATmega32U4 8-bit AVR microcontroller and an Espressif Systems ESP8266 WiFi SoC. Egypt-based UNIT 72784 says their cyber security tool enables Red Teaming – the practice of rigorously identifying an attack path to breach a device’s security – as it behaves like a flash drive while being able to deploy keyboard strokes wirelessly through the ESP8266 WiFi MCU. Diabolic Drive specifications: MCUs Microchip ATmega32U4 microcontroller @ 16 MHz (5V) acting as a Serial Bridge Espressif Systems ESP8266EX microcontroller @ 160 MHZ (3.3V) with WiFi 4 support ATmega32U4 and ESP8266 are connected via Serial and I2C protocols thanks to an LDO regulator.

An ESP32-S3 board for vending machines with RS485, microSD card slot, optional cellular mPCIe module

LILYGO T Vending

LILYGO T-Vending is an ESP32-S3 WiFi and Bluetooth IoT board designed for vending machines with an RS485 terminal block, a microSD card slot, and support for an optional cellular mPCIe module. As I understand the board is connected to the vending machine through the RS485 terminal block to control vend motors (potentially via an additional board to control multiple motors) and a 10-pin connector for power (12V/24V), signals to/from a coin mechanism and other parts. The board also adds a Grove connector and an unpopulated 12-pin GPIO header for expansion. T-Vending 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 Wireless 2.4 GHz 802.11n WiFi 4 and Bluetooth 5.0 LE connectivity (ESP32-S3) Optional T-PCIe 4G LTE […]

WeAct launches $6 ESP32-C6 development board, ESP-IDF 5.1 framework released

WeAct ESP32-C6 development board

As expected, Espressif has just released the ESP-IDF 5.1 framework with ESP32-C6 and ESP32-H2 support, so more ESP32-C6 boards should become available, and after Olimex ESP32-C6-EVB launched earlier this week, we’ve noticed WeAct had introduced a low-cost ESP32-C6 development board that sells for just $6.43 plus shipping a few weeks ago. WeAct ESP32-C6 board The WeAct board offers 2.4 GHz WiFi 6, Bluetooth LE 5.0., and Zigbee/Thread connectivity through the ESP32-C6-WROOM-1 module, two USB-C ports, two 16-pin headers for GPIOs, and if it looks familiar, it’s because it closely follows the design of the official ESP32-C6-DevKitC-1 development kit, albeit with some small modifications. WeAct ESP32-C6 board specifications: Wireless module  – ESP32-C6-WROOM-1 with ESP32-C6 single-core 32-bit RISC-V clocked up to 160 MHz, with 320KB ROM, 512KB SRAM, low-power RISC-V core @ up to 20 MHz Wireless – 2.4 GHz WiFi 6, Bluetooth 5.0 LE, 802.15.4 radio for Zigbee 3.0 and Thread.
