SparkFun’s latest development board, the ESP32 Qwiic Pro Mini, puts the Espressif ESP32-PICO-MINI-02 on a compact Arduino Pro Mini footprint. It also includes an onboard QWICC connector for easy interfacing with a wide range of sensors and peripherals. We have already covered other Sparkfun dev boards like DataLogger IoT, Datalogger IoT – 9DoF, and SparkFun Thing Plus Matter you can check those out if interested. Like any other ESP32 board, this also uses an ESP32 microcontroller which features a 32-bit dual-core processor, 520kB of SRAM, 2MB of PSRAM, 8MB of flash memory, and 16 kB of additional SRAM in its RTC. It supports Bluetooth 4.2 and BLE and has ADC and DAC, touch detection, PWM, TWAI, Ethernet MAC, UART, SPI, SDIO, I2C, and I2S interfaces. As reported in a Hackster article, the board also features a Qwiic Connector for solderless connections to sensor boards and add-ons, positioned at a 90-degree angle […]

Microflex MCUs – Tiny USB development boards based on ESP32-S3, ESP32-S2, ESP32-C3, ESP32-C6, or Raspberry Pi RP2040 (Crowdfunding)
SB Components is back with yet another crowdfunding campaign this time with the Microflex MCUs USB development boards all with the same tiny form factor and offered with a choice of five microcontrollers namely Raspberry Pi RP2040, ESP32-S3, ESP32-S2, ESP32-C3, or ESP32-C6. Microflex MCUs share the same layout with a USB-C port for power and programming, a built-in RGB LED, two buttons for Boot and Reset/User, and two rows of 10-pin with through and castellated holes to access the GPIOs and power signals such as 5V, 3.3V, and GND. But they differ in terms of the processor used, wireless features, and available I/Os as shown in the table below which sadly lacks any information about the flash and eventual PSRAM… The illustration below includes some more details for the Micro-C6 with the main components, ports, and a pinout diagram. Programming the firmware for the ESP32-series can be done through the […]
Arduino Portenta X8 achieves EU’s Cyber Resilience Act (CRA) compliance
Foundries.io, in collaboration with Arduino, has integrated its security software into the Portenta X8, making it the first system-on-module (SoM) to achieve CRA Compliance with the European Union’s Cyber Resilience Act (CRA). Last year, we covered the Portenta X8, Arduino’s first board with an Arm processor running Linux with expansion capabilities with add-ons such as the Portenta HAT Carrier Board, and you’ll find more details about the hardware in those posts. This new EU’s CRA specifies minimum security for all IoT devices in Europe from 2025. This includes: Establish standards for secure products with digital elements throughout the EU. Require manufacturers to focus on security at every stage of a product’s life. Increase user awareness of a product’s cybersecurity features. Demand that Original Equipment Manufacturers (OEMs) quickly address vulnerabilities in devices already in use. All these rules will be applicable for the full lifespan of the devices. Under the upcoming […]
NORVI ESP-HMI-5C ESP32-based HMI features a 5-inch resistive touchscreen display
NORVI ESP32-based human-machine interface (HMI) solution features a 5-inch LCD with a resistive touchscreen driven by an ESP32-S3 wireless module and support for the LVGL library. NORVI previously brought us some headless ENET industrial controllers including some with Ethernet beside the WiFi connectivity built into the ESP32 microcontroller, but the NORVI HMI device is the first product from the company with a proper display suitable for HMI applications. NORVI HMI (ESP-HMI-5C) specifications: Wireless module ESP32-S3-WROOM32-1-N16R8 MCU – ESP32-S3 dual-core LX7 microprocessor @ up to 240 MHz with Vector extension for machine learning, 512 KB SRAM Memory – 8MB octal SPI PSRAM Storage – 16MB flash Connectivity – WiFi 4 and Bluetooth 5 with LE/Mesh PCB antenna Storage – MicroSD card slot (SPI interface) Display – 5-inch LCD Display with Resistive Touch Audio – Built-in Buzzer Communication interfaces – Ethernet (W5500) and RS485 I/Os 4x digital inputs – Range 18V to 32V […]
LILYGO Mini E-Paper Core IoT controller gets ESP32-S3 wireless microcontroller
LILYGO Mini E-Paper Core has gotten an upgrade to the ESP32-S3 wireless microcontroller. The IoT controller was first introduced in 2021 with an ESP32-PICO-D4 system-in-package, a 1.02-inch E-Paper display, and a few GPIOs on the back, and the company kept the same design for the ESP32-S3 model called “Mini E-Paper Core S3”. The tiny ESP32-S3 IoT controller can still be used for integrated into your own project, and the company also provides several shields with nRF24L01 2.4GHz wireless or 433/868 MHz “LoRa” connectivity to transform the device into a longer range IoT device. Mini E-Paper Core S3 specifications Wireless SoC – Espressif Systems ESP32-S3FN4R2 CPU – Dual-core Tensilica LX7 @ up to 240 MHz with vector instructions for AI acceleration Memory – 512KB RAM, 2MB PSRAM Storage – 4MB flash Wireless – 2.4 GHz WiFi 4 and Bluetooth Storage – MicroSD card socket Display – 1.02-inch e-paper display with 128×80 […]
OpenMV CAM RT1062 camera for machine vision is programmable with MicroPython
Following the success of the OpenMV Cam H7 and the original OpenMV VGA Camera, OpenMV recently launched the OpenMV CAM RT1062 powered by NXP’s RT1060 processor. This new camera module integrates a range of features, including a high-speed USB-C (480Mbps) interface, an accelerometer, and a LiPo connector for portability. Similar to its predecessor, this camera module also features a removable camera system, and it is built around the OV5640 image sensor which is more powerful in terms of resolution and versatility. However, the previous Omnivision OV7725 sensor, used in the OpenMV Cam H7 has a far superior frame rate and low-light performance. OpenMV provides a Generic Python Interface Library for USB and WiFi Comms and an Arduino Interface Library for I2C, SPI, CAN, and UART Comms which can be used to interface your OpenMV Cam to other systems. To program the board, you can use MicroPython 3 with OpenMV IDE, […]
Tiny Raspberry Pi RP2040 module connects to USB-C + buttons board via FPC connector
Waveshare RP2040-Tiny is another tiny Raspberry Pi RP2040 module that joins others like Pimoroni Tiny 2040, DFRobot Beetle RP2020, or Solder Party RP2040 Stamp, but with a twist as the solderable module features an FPC connector in order to optionally connect a separate board with a USB-C port as well as Boot and Reset buttons. This design enables the convenience of having a USB-C port for power and programming, plus the Reset and Boot buttons during firmware development, and developers can only keep the tiny and ultrathin module when integrating it into a project or product. Alternatively, there may be designs that benefit from having the USB-C port located further away from the main module with all I/Os, and it can also facilitate troubleshooting when the product is already integrated into a product. Waveshare RP2040-Tiny specifications: MCU – Raspberry Pi RP2040 dual-core Cortex-M0+ microcontroller @ up to 133Mhz with 264kB […]
