ESP32 CoinCell is a Tiny, Coin Cell Powered ESP32 Pico D4 Board

ESP32 CoinCell

ESP32 boards can easily be powered by batteries, either through an external USB battery shield, or direct connection to an ESP32 board fitted with battery charger circuitry. But Miek Rankin has done something a bit different, as he designed ESP32 Coincell board based on an ESP32 Pico D4 SiP (System-in-Package) powered by a rechargeable LIR2450 coin cell battery with 100mAh capacity. ESP32 CoinCell board specifications: SiP – Espressif Systems ESP32 Pico D4 Wifi/Bluetooth processor Connectivity 802.11 b/g/n WiFi up to 150 Mbps Bluetooth 4.1 LE On-board antenna Display – 0.69″ OLED display with 96×16 resolution USB – 1x micro USB port for charging and debugging (via CP2102N USB to TTL chip) Sensor – LIS3DHTR accelerometer Battery / Power Supply SE5218ALG-LF 500mA LDO power supply SL4054ST25P LiPo battery charger Socket for  for LIR2450 (3.7V/100Mah battery) Consumption – 0.45mA in sleep mode Dimensions – Small If you don’t connect the battery, the board can still be powered through the USB port. No battery …

Arduino IoT Cloud Public Beta Launched

Arduino IoT Cloud Thing Widget

It’s long been possible to get data from sensors connected to official or compatible Arduino board, upload it to some cloud services, and watch the results is a neat web interface. But until now, you had to rely on third party services such as ThingSpeak, Adafruit.io, or Thinger.io to name a few. Arduino has now announced their own Arduino IoT Cloud services is entering public beta. You’d normally need to modify the sketch by hand to connect an Arduino board to the cloud, but Arduino IoT Cloud can automatically generate a sketch when setting up a new project, and help you get started quickly in less than five minutes. The Arduino IoT Cloud supports HTTP REST API, MQTT, Command-Line Tools, Javascript, and Websockets, and devices are secured using X.509 certificate-based authentication. To get started, you’ll need an Arduino MKR board, and create an account or login to Arduino IoT Cloud. Two boards can be selected from the interface: MKR1000 or …

OpenISA VEGAboard Combines RISC-V and ARM Cortex-M Cores

VEGAboard

OpenISA has launched an Arduino compatible RISC-V development called VEGAboard that features RV32M1 wireless microcontroller with a RISC-V RI5CY core, a RISC-V ZERO-RISCY core as well as Arm Cortex-M4F and Cortex-M0 cores, and a radio operating in the 2.36 GHz to 2.48 GHz range. An external NXP Kinetis K26 Arm Cortex-M4 MCU is added to the board for OpenSDA (Open-Standard Serial and Debug Adapter) debugging over a single USB cable. The board was offered for free, I’m just not sure when, but they are already out of stock. Hopefully, they’ll start selling the board soon enough. VEGAboard (RM32M1-VEGA) board key features and specifications: Ultra-low-power RV32M1 Wireless MCU supporting BLE, Generic FSK, and IEEE Std 802.15.4 (Thread) platforms IEEE Std. 802.15.4-2006 compliant transceiver supporting 250 kbps O-QPSK data in 5.0 MHz channels, and full spread-spectrum encoding and decoding Fully compliant Bluetooth v4.2 Low Energy (BLE) Reference design area with small-footprint, low-cost RF node: Single-ended input/output port Low count of external components …

XinaBox’s xChips Enable Modular Electronics for Makers & STEM Education

Xinabox xCHIPS ESP8266 UV Index Monitor

So today, I decided to have a look a 96Boards website to see if there was anything new from the community, and I came accross “X in a Box B901“, an “☒CHIP is designed to interface with the 96 Boards, such as the Dragonboard 410c. This provides an interface to support the ☒CHIP ecosystem, adding support for many additional sensors etc…” I had no idea what it was all about, so obviously I had to investigate. Xinabox (X in a Box) is an ecosystem of modular electronics boards used for developing, making products and learning. There are now over 70 modular xChip” with cores/CPUs, sensors, power, communication, output, and storage. They are interconnected together without wires, soldering, breadboards, and adapters are provided for Raspberry Pi, 96Boards, and other development boards. xChips can be sorted into 8 categories: Cores – MCU/CPI cores based on Microchip ATMega328P, SAMD21, ESP8266, or ESP32 with or without a LoRa radio Bridges – Used to connect …
