Google Cloud IoT Core Enters Public Beta, Various Devkits Available

Back in May, I wrote about Allwinner R18 based Banana Pi BPI-M64 Board with Google Cloud IoT Core support, as Google unveils the new cloud service during Google I/O. However, at the time it was only available to selected partners, and Google has recently launched the public beta making their IoT device management platform available to all. I first learned about this through an ARM community blog post announcing availability of the ARM-based IoT Kit for Cloud IoT Core on Adafruit using Raspberry Pi 3 board, a breadboard, and various modules that can be managed through Google services. But that are plenty of other IoT kits or boards for Google Cloud IoT Core including: Allwinner R18 based Pine A64-LTS, Banana Pi BPI-R18 Marvell based MACCHIATObin, and ESPRESSOBin boards Mongoose OS IoT starter kit with ESP32 board( instead of Raspberry Pi 3) Grove IoT Commercial Developer Kit based on Intel NUC […]

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: […]

Need to Program Many ESP-WROOM-32 / ESP-32S Modules? This Board Should Help

We’ve just published an article about a 3D printed jig to program some ESP8266 light bulbs, but as I watched Andreas Spiess’s latest video about ESP32 boards, he showed a board specifically designed to flash firmware to ESP-WROOM-32 or/and ESP-32S modules, which could be useful if you have many to program. The acrylic base does not appear to be offered by all vendors, as some use some standoffs instead to lift the board up. You just need to insert your compatible ESP32 module in the board, flash the firmware it, take it out, and more to the next module. It can also be used as a development board since it exposes I/Os via three 14-pin headers, comes with a on/off button, reset and program buttons, as well as a micro USB port for power, programming and debugging I first found it on Banggood, where it is sold for $14.99 shipped, […]

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 […]

Getting Started with Espruino & JavaScript on ESP32 with ESPino32 Board

Venus Supply Co., Ltd, better known as ThaiEasyElec, is a company based in Thailand, selling embedded systems and development board, as well as providing development services based in Thailand. The company sent me their latest board called ESPino32 powered by Espressif ESP-WROOM-32 WiFi and Bluetooth module for evaluation. While the board is supported in Arduino-esp32, I’ve already tested Arduino with ESP32-Bit module & ESP32-T board, so after checking out the hardware, I’ll load it with something different: Espruino, a firmware allowing for JavaScript programming over the serial console, or a Web based IDE. ESPino32 Unboxing and Soldering The board shipped with four female headers, and I/O stickers. The board includes ESP-WROOM-32, exposes I/Os through four 10-pin headers, features CP2104 chip for serial to USB debugging via micro USB port, two buttons (reset and program), a user LED connected to IO16, and a jumper to select between regulated power supply (micro […]

Geekcreit ESP32 Development Board Goes for $4 Shipped (Promo)

While you may have thought Wemos Lolin32 board selling for $6.9 plus shipping was already a decent deal, you can now buy a breadboard friendly ESP32 development board for the normal price of ES8266 board thanks to a promotion on Banggood selling 1,000 pieces of “Geekcreit ESP32” board for $4.09 including shipping, and valid until September 10, or while stock lasts. It looks to be roughly the same design as the fake NodeMCU ESP-32s board I once spotted: Wireless Module – ESP-WROOM-32 with Espressif ESP32 dual core processor with 802.11 b/g/n WiFi and Bluetooth 4.0 LE Expansion – 2x 19 pin headers with GPIOs, Analog inputs (ADC), UART, I2C, VP/VN, etc…; breadboard compatible USB – 1x micro USB port for power and programming Misc – BOOT and EN buttons, red (power) and blue (GPIO2) LEDs Power Supply – 5V via USB or Vin pin Dimensions – 51.4 x 28.3 mm […]

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 […]

A First Look at ESP32 PICO Core Development Board Powered by ESP32-PICO-D4 SiP

Last week, I wrote about ESP32-PICO-D4 system-in-package (SiP) that contains ESP32 WiSoC, 4MP SPI flash, a crystal oscilloscator and some passive components in a single 7×7 mm package in order to allow smaller designs based on ESP32. The company noticed the post, and asked me whether I’d be interested in receiving “some development boards based on ESP32 PICO”, an offer hard to refuse :), and within a couple of days I received the package below. So I ended up with 10 identical development kits, the company probably thought it was no worth paying for DHL to only send one or two development boards… The boards may also be part of some contests… We’ll see 😉 So let’s take two, and have a closer look at “ESP32_PICO_Core_Board_V3″… It comes with two rows of 20 pins with access to all I/Os, and features three main chips: ESP32-PICO-D4 SiP, AMS1117 voltage regulator, and Silabs […]
