MicroMod modular ecosystem offers M.2 microcontrollers cards and carrier boards

MicroMod is a modular interface ecosystem for quick embedded development and prototyping. MicroMod comes with two components, that is a microcontroller “processor board” and a carrier board. PC industry’s M.2 connector is the interface between these two components. The carrier boards are for the usage of various peripherals and the processor board act as the brain of the application system. MicroMod processor board has a dimension of 22×22 mm that can be easily fitted on the carrier boards. Although, the original M.2 standard was dedicated to swapping out peripherals where a user could swap one component with the other one. The MicroMod standard is for swapping out microcontrollers according to the functional and application requirements. MicroMod Processor Boards Artemis Processor Board comes with an Ambiq Apollo 3 Blue Arm Cortex-M4F with BLE 5.0 running up to 96MHz and a power rating of less than 5mW. It also supports the TensorFlow […]

Oplà IoT Kit is Arduino’s first open programmable IoT platform

Arduino is well-known for its maker boards and shields that are sometimes sold as part of kits to experiment with electronics. Arduino Oplà IoT kit is a little different as it looks more like an actual consumer product once assembled. Powered by an Arduino MKR WiFi 1010 board, it is designed to make getting started with IoT easy for beginners, while still allowing more advanced users to customize and hack their smart home applications. Arduino Oplà IoT Kit is comprised of several hardware components: MKR IoT carrier with a 1.2-inch OLED color display, onboard environmental sensors (temperature, humidity, pressure, light, and proximity), IMU sensor, Grove connectors, two 24V relays, and five capacitive touch buttons. Arduino MKR WiFi 1010 board powered by Microchip SAMD21 Cortex-M0+ MCU and equipped with a 2.4 GHz WiFi 4 and Bluetooth 4.2 module based on ESP32 chip. Sensors – PIR motion sensor and moisture sensor A […]

JPEGDEC is a Faster JPEG Arduino Library Designed for 32-bit MCUs

In order to ensure software compatibility, Arduino libraries are supposed to work on various types of hardware from 8-bit microcontrollers with a limited amount of memory to more powerful 32-bit chips like STM32 Arm Cortex-M MCU or ESP32 dual-core Tensilica WiSoC that can access a larger amount of RAM. This is all good, but in some cases, this may affect performance. Larry Bank noticed this when looking for a JPEG viewers for Arduino and only found ones which sacrificed speed to work on MCUs with very little RAM. So he started to work on JPEDDEC JPEG Arduino library optimized for speed and compatible with any MCU with at least 20K of RAM. Optimizations go beyond just loading more data into memory, as Larry explains in a blog post, the library also performs the removal of stuffed bytes, optimize the Huffman decode and DCT parts, and more. Some of the key […]
