TECHBASE Moduino X Series Industrial IoT Modules / Endpoints are Based on ESP32 WiSoC

We’ve previously covered TECHBASE ModBerry industrial IoT gateways leveraging Raspberry Pi 3, FriendlyELEC NanoPi M1 Plus, or AAEON’s UP Linux boards. The company has now launched Moduino X series modules powered by Espressif ESP32 WiFi + Bluetooth SoC to be used as end points together with their ModBerry gateways. Two models have been developed so far, namely Moduino X1 and X2, with the following specifications: Wireless Module – ESP32-WROVER with ESP32 dual-core Tensilica LX6 processor @ 240 MHz, 4MB pSRAM (512KB as option), 4MB SPI flash; External Storage – X2 only: micro SD card slot Connectivity 802.11 b/g/n WiFi up to 16 Mbps + Bluetooth 4.2 LE with u.FL antenna connector X2 only: 10/100M Ethernet Options: LoRa (Semtech SX1272); Sigfox (TI CC1125); LTE Cat M1/NB1; Zigbee Serial – 2x RS-232/485 Display – Optional 0.96″ OLED display with 128×64 resolution Expansion I/Os 4x Digital I/O (0 ~ 3V) 2x Analog Input: […]

Wemos LOLIN32 Lite Board Powered by ESP32 Rev 1 Chip Sells for $4.90

Wemos introduced the first low cost ESP32 board with LOLIN32 board going for $6.90 plus shipping in April, but the company is now back with a new Lite version of the board switching ESP-WROOM-32 module with their own design around ESP32 Rev 1 chip (with various silicon bug fixes), and a lower $4.90 price tag to which you need to add ~$2 for shipping. Wemos LOLIN32 Lite is also smaller, so we’ll lose some of the pins (mostly extra power pins), but the I/Os look the same: SoC – Espressif ESP32-DOWD6Q Rev 1.0 dual core Tensilica Xtensa LX6 processor with WiFi and BLE Connectivity – 802.11 b/g/n WiFi + Bluetooth LE I/Os via 2x 13-pin headers with digital I/Os, analog inputs, UART, I2C, SPI, VP/VN, DAC… 3.3V I/O voltage Breadboard compatible USB – 1x micro USB port for power and programming/debugging Misc – Reset button Power – 5V via micro […]

Realtek RTL8195AM Ameba WiFi + NFC Module Sells for $9 Shipped

Last year, Realtek Ameba IoT SoCs and development kits launched with boards such as Ameba Arduino, and later, the family got some buzz thanks to $2 RTL8710AF modules like Pine64 Padi IoT stamp, which looked competitive priced against ESP8266 SoC, and featuring an ARM Cortex-M3 core. Back to 2017, ESP8266 appears to still be the preferred platform for makers, and the community around Reatek Ameba processor is relatively small, but maybe the solutions are being integrated into commercial products rather than hobbyists project. Today, as I browsed the web, I noticed that are also some Realtek RTL8195AM module with WiFi, and NFC starting with an “Realtek Ameba-RTL8195AM WiFi & NFC Module” I first found on DFrobot for $15 per unit, but after spending a bit more time searching, I ended finding what looks like the same model for $8.99 including shipping on IC Station. RTL8195AM module (MJIOT-AMB-02) specifications: SoC – […]

FOSDEM 2017 Open Source Meeting Schedule

FOSDEM (Free and Open Source Software Developers’ European Meeting) is a 2-day free event for software developers to meet, share ideas and collaborate that happens on the first week-end of February, meaning it will take place on February 4 & 5, 2017 this year. FOSDEM 2017 will features 608 speakers, 653 events, and 54 tracks, with 6 main tracks namely: Architectures, Building, Cloud, Documentation, Miscellaneous, and Security & Encryption. I won’t be there, but it’s always interesting to look at the schedule, and I made my own virtual schedule focusing especially on talks from “Embedded, mobile and automotive” and “Internet of Things” devrooms. Saturday 4, 2017 11:00 – 11:25 – Does your coffee machine speaks Bocce; Teach your IoT thing to speak Modbus and it will not stop talking, by Yaacov Zamir There are many IoT dashboards out on the web, most will require network connection to a server far […]

$55 OpenMV Cam M7 Open Source Computer Vision Board is Powered by an STM32F7 Cortex-M7 MCU

I wrote about Jevois-A33 computer vision camera based on Allwinner A33 quad core Cortex A7 processor last week, and today, I’ve come across OpenMV Cam M7 open source computer vision board based on a much less powerful STMicro STM32F7 ARM Cortex M7 micro-controller, but with the advantage of consuming less power, and exposing some extra I/Os. OpenMV Cam M7 board specifications & features: MCU – STMicro STM32F765VI ARM Cortex M7 @ up to 216 MHz with 512KB RAM, 2 MB flash.

Embedded Systems Conference 2016 Schedule – April 13-14

The Embedded Systems Conference 2016 will take place in Boston on April 13-14, and the organizers have now released the schedule, minus some keynotes, which features four main tracks: Embedded Hardware, Embedded Software, Connected Devices and the Internet of Things (IoT), and the ESC Engineering Theatre. As usual, I’ve gone through the list of talks and composed my own little virtual schedule which ended up with sessions focusing on power management, IoT, and security, as well some optimization and drivers development talks among others, such as patents, and the origin of Gerber files. Wednesday 13 8:00 – 9:00 – Power Management in Embedded Systems by Colin Walls, Embedded Software Technologist, Mentor Graphics The importance of power management in today’s embedded designs has been steadily growing as an increasing number of battery powered devices are developed. In this session, we will discuss design considerations that should be made when starting a […]
