New Espressif ESP32 Single and Dual Core Processors in 5x5mm Package, Optional Embedded Flash Coming Soon

Espressif ESP32 was launched last year as a dual core Tensila processor with WiFi and Bluetooth connectivity, relying on external flash for storage, and packaged into a QFN48 6x6mm package. Espressif recently updated ESP32 datasheet, and the guys at ESP32net noticed three new versions of the processor with a QFN48 5x5mm package, one version including 2 MBytes embedded flash, and another version with a single core. The three new versions of ESP32 all come with the same WiFi 802.11b/g/n ad Bluetooth 4.0 LE connectivity and a QFN 5×5: ESP32-D0WD dual core processor without embedded flash ESP32-D2WD dual core processor with 16 Mbit embedded flash ESP32-S0WD single core processor without embedded flash ESP32-D0WD different with ESP32-D0WDQ6 is only the smaller package, while ESP32-D2WD brings 2MB embedded flash too possibly lowering the price of current solution with external flash, and ESP32-S0WD might be closer to ESP8266 price thanks to its single core, […]

Is NodeMCU ESP-32S Board Now Selling for $8.50 Shipped?

ESP32 SoC with WiFi and Bluetooth launched last September for around $3, followed soon after by ESP32 modules for $7, and a few weeks later, easier to use ESP32 development boards were introduced, but sold for around $20 likely due a mismatch between supply and demand. That’s not overly expensive, but in a world of $4 ESP8266 boards and $10 Raspberry Pi Zero W with Linux, WiFi and Bluetooth, it may feel that way. But today, I noticed DealExtreme sold GeekWorm ESP32 board with ESP-WROOM-32 module for just $11.64 shipped. That’s good progress, but surely Aliexpress must now have cheaper options, and sure enough, I could find NodeMCU ESP-32S board (now confirmed NOT to be an official NodeMCU devkit) sold for $6.95 + shipping, which brought the price up to about $8.50. NodeMCU ESP-32S specifications: Wireless Module – ESP-WROOM-32 with Espressig ESP32 dual core processor with 802.11 b/g/n WiFi and […]

Texas Instruments CC3200 WiFi SensorTag is Now Available for $40

Texas Instruments launched SensorTag in 2013, and at the time there was just a Bluetooth 4.0 LE version with 6 different sensors. I bought one for $25 at the time, and tried it with a Raspberry Pi board and a BLE USB dongle. Since then, the company has launched a new multi standard model (CC2650STK) supporting Buetooth low energy, 6LoWPAN, and ZigBee, and has just started to take orders for CC3200 WiFi SensorTag for $39.99, which seems expensive in a world of $2 ESP8266 modules. But let’s see what the kit has to offer: Wireless MCU – Texas Instruments CC3200 SimpleLink ARM Cortex-M4 MCU @ up to 80 MHz, with up to 256KB RAM, Hardware Crypto Engine, DMA engine Storage – 1 MB serial flash memory Connectivity – 802.11 b/g/n WiFi with on-board inverted-F antenna with RF connector for conducted testing Sensors – Gyroscope, accelerometer, compass, light sensor (OPT3001), humidity […]
