Seeed Studio’ Latest entry in their Arduino based Seeeduino family Comes to a tiny 23.5mm x 17.5mm dimension. The XIAO Development Board packed with Microchip’s ATSAMD21 microcontroller. The XIAO Development Board can be easily integrated into any wearables project . The Seeeduino XIAO is also a breadboard-friendly development board that’s similar to Adafruit’s Trinket M0 and Attiny85 based digispark. The only difference is it packs a more advanced processor (ATSAMD21G18 vs. ATSAMD21E18), adds more GPIOs, and is significantly smaller in size.

The XIAO Development Board features a 32-bit Arm Cortex-M0+ CPU with a 256Kb of Flash memory and 32Kb of SRAM. The XIAO is offering 14 GPIO pins, 11 analog pins, 11 digital pins, 10 PWM pins, and a DAC pin. It also packed with I2C, UART, and SPI interfaces. Along with a USB Type-C port, Few LEDs, one reset button, power out pads (for battery power). It has an operating voltage of 3.3V.

The Seeeduino XIAO is a breadboard-friendly development board that’s similar to Adafruit’s Trinket M0. Only it packs a more advanced processor (ATSAMD21G18 vs. ATSAMD21E18), adds more GPIOs, and is significantly smaller in size.

The back of the Seeeduino XIAO features four power pads designed for hooking batteries for battery-powered operations. This makes the development board ideal for wearables and other portable projects that don’t require connected power. SeeedStudio also states that they have added an extra 32.768KHz to the MCU’s internal crystal oscillator. For Help on time fixing with added stability and accuracy. Wich is a better way of approach from SeedStudio

Programming the board made simple as well the board makes use of the Arduino IDE and its extensive library. SeeedStudio is currently offering the Seeeduino XIAO on its product page. Which retails for just $4.90,.Making it one of the cheapest SAMD21-based boards on market right now!

STMicroelectronics has announced the first LoRa SoC, Named STM32WLE5 well Designed for the long-range and low-power wide-area networking.

However, the STMicro’s STM32WLE5 is not only the first SoC(System on Chip) to integrate LoRa connectivity. Their first claim comes from the fact that it is the world’s first to place it on a die. Rather than simply integrating on the same main SoC hardware.

The STM32WL comes with an Arm Cortex-M4 processor running at 48MHz with DSP (digital signal processor ) and memory protection unit. It comes with up to 256kB of flash memory and up to 64kB of SRAM.

The radio system supports LoRa modulation alongside (G)FSK, (G)MSK, and BPSK, and works from 150MHz up to 960MHz. With one output running up to 22dBm and the other optimized for power consumption, running at up to 15dBm.

The Semtech SX1262 sub-gigahertz radio thus finds itself closer to the heart of the design. which could potentially spell good news for power draw.

While looking to the security side of the design. It includes AES 128- and 256-bit off acceleration. Fully hardware-level random number generator, a private key accelerator, and a 96-bit ID unique to each chip. Connectivity includes two SPIs, three I2Cs, one ultra-low-power UART, two USART, seven 16- and 32-bit timers. It also comes with One analog to digital (ADC) and digital to analog converters (DAC) at a 12-bit of resolution. The SoC also comes with an onboard temperature sensor and two ULP comparators. Also plus up to 43 general-purpose input/outputs (GPIOs).

 The open-source hardware platform Arduino.cc today launched the new low-code platform and modular hardware system for IoT development. The whole concept is here to support small and medium tech businesses the tools to develop IoT hardware products without having to invest in specialized technology resources.

The new hardware board named the Arduino Portenta H7, which features everything needs to get started with making an IoT hardware solution for small and medium businesses, including a wide range of features, crypto-authentication chip and communications modules for Wi-Fi, Bluetooth Low Energy, and also comes LTE which is arrow band IoT.

Powered by 32-bit Arm microcontrollers, Portenta combined with Cortex-M7, these low-power modules are meant for designing the industrial applications as well as edge processing solutions and robotics applications. It shall support a wide range of coding platform like Arm’s Mbed OS, support Arduino code, Python and JavaScript applications.

Built on Arm Pelion technology, the latest generation of Arduino solutions brings users the simplicity of integration and a scalable, secure, professionally supported service. 

Official comment from arduino.cc :

“By combining the power and flexibility of our production ready IoT hardware with our secure, scalable and easy to integrate cloud services, we are putting in the hands of our customers something really disruptive,” commented Arduino CEO Fabio Violante. “Among the millions of Arduino customers, we’ve even seen numerous businesses transform from traditional ‘one off’ selling to subscription-based service models, creating new IoT-based revenue streams with Arduino as the enabler. The availability of a huge community of developers with Arduino skills is also an important plus and gives them the confidence to invest in our technology”. 

The new H7 portenta module is now available for beta testers, with general availability dated for February 2020.
