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 […]

Aconno Bluetooth 4.0 & 5 IoT Development Board Features an nRF52832 or nRF52840 Module, an e-Paper Display, Sensors and More

Bluetooth 5 is the latest iteration of Bluetooth with up to four times the speed and twice the range of Bluetooth 4.0 LE, and so far apart from Puck.js and Nordic Semi nRF52840 devkit, I had not seen many Bluetooth 5 IoT modules or boards. Aconno, a German startup, has designed ACD-52832 Bluetooth 4.0 / Thread / ANT+ IoT development board based on their own nRF52832 module, and equipped with some goodies like a black & white e-Paper display, a joystick, sensors, I/Os, etc… They’ve also launched an updated module with Bluetooth 5 using nFR52840 SoC. I don’t have the full details about the new module, but the nRF52832 module and devkit is interesting to look at, especially features should be similar. Aconno ACD-52832 board specifications: Wireless Module – ACN52832 based on Nordic Semi nRF52832 ARM Cortex-M4 @ 64 MHz SoC with Bluetooth Smart, ANT+, Thread, NFC, and 2.4 GHz […]

MeLE V9 4K Android TV Box Comes with a 3.5″ SATA Slot, a Cooling Fan

We’ve seen several devices based on Realtek RTD1295 processor. They all come with a SATA interface, either via an external connector like Zidoo X9S, a 2.5″ SATA bay like Beelink SEA I, or a 3.5″ SATA bay as found in Eweat R9 Plus. However, all those devices are fanless, and at least one person expressed concerns when using a device with an internal hard drive without active cooling. MeLE V9 fills that gap, as the RTD1295 TV box features a 3.5″ SATA slot and an active fan for cooling both the device and the hard drive. MeLE V9 specifications: SoC – Realtek RTD1295 quad core Cortex A53 processor with ARM Mali-T820 MP3 GPU System Memory – 2GB DDR3 Storage – 16GB eMMC flash + 3.5″ SATA slot + SD/SDXC card slot Video I/O – HDMI 2.0a output up to 4K @ 60 Hz with 10-bit HDR support, AV port, and […]

Intel: My 10nm Process is Denser Than Yours

Process technology is important as the lower the process node, the more efficient the processor becomes, which leads to either longer battery life for the same tasks on battery powered devices, or allows for higher frequencies extracting more performance. Qualcomm and Samsung recently announced Snapdragon 835 SoC was manufactured using 10nm process technology, but Mark Bohr, an Intel Senior Fellow and director of process architecture and integration at Intel Corporation. wrote a blog post explaining that while in the past process node size and density were progressing in a “linear” fashion, this is not the case anymore, as marketing has changed, and some companies advance node names, even in cases where there’s minimal or no density increase. The chart above implies that some companies 10nm process is barely better than Intel’s 14 nm process, with their 10nm process capable of integrating about twice as much transistors per square millimeter compare […]
