ESPDUINO-32 & Wemos D1 R32 ESP32 Boards Support (Most) Arduino UNO Shields

The compact ESP32 NodeMCU like board are great for many project, but in case you plan to leverage your existing Arduino shield, it’s more convenient to have a compatible board. We’ve previously seen Noduino Quantum board sold for 99 RMB on Taobao, and $25.90 on AnalogLamb, but doit.am has designed a cheaper model called ESPDUINO-32 that supports shields compatible with Arduino UNO, and sold for $13.73 on DealExtreme. ESPDUINO-32 board specifications: Wireless Module – ESP-WROOM-32 based on Espressif ESP32 dual core Tensilica LX6 processor with 802.11 b/g/n WiFi and Bluetooth 4.2 LE Expansion – Arduino UNO headers with SPI, I2C, digital I/Os, 1x analog input up to 3.2V, 5V, GND USB – 1x USB device port Misc – Button Power Supply – 5 to 12V input via DC jack or Vin pin Dimensions – 66 x 53.3 x 13.5 mm The board can be programmed with the Arduino IDE selecting […]

Embedded Linux Conference & Open Source Summit Europe 2017 Schedule

The Embedded Linux Conference & IoT summit 2017 took place in the US earlier this year in February, but there will soon be a similar event with the Embedded Linux Conference *& Open Source Summit Europe 2017 to take up in Europe on October 23 – 25 in Prague, Czech Republic, and the Linux Foundation has just published the schedule. It’s always useful to find out what is being discussed during such events, even if you are not going to attend, so I went through the different sessions, and compose my own virtual schedule with some of the ones I find the most interesting. Monday, October 23 11:15 – 11:55 – An Introduction to SPI-NOR Subsystem – Vignesh Raghavendra, Texas Instruments India Modern day embedded systems have dedicated SPI controllers to support NOR flashes. They have many hardware level features to increase the ease and efficiency of accessing SPI NOR […]

Checking out Hologram’s Developer SIM Card for Worldwide IoT Projects

Hologram is a service that offers 2G/3G/4G cellular connectivity for the Internet of Things via a SIM card that works in over 170 countries, and with pricing starting at $0.40 per month. In order to promote their services, the company offers a free developer SIM card which I ordered when I first wrote about the service last month. I was pleased and surprised they would sent it to Asia for free, and I got the card in a bubble envelop. The back of the card includes a 18 to 22 digit SIM card number and bar code, that we’ll need to use for activation, and a link that redirects to https://hologram.io/docs/. I planned to try the card with Wio GPS tracker board which requires a nano SIM card, and there are convenient cutouts to convert the SIM card to micro SIM or nano SIM card formats. Before using the card […]
