Espressif is Working on a New Wi-Fi and Bluetooth LE Chip with Hardware SSL Support

Espressif came to fame thanks to its low cost ESP8266 WiFi chip which was originally designed for connected lightbulbs, but soon got used in a variety of  applications, and ESP8266 modules must now be the most popular solutions to add WiFi to IoT projects, as long as they are not battery powered. The company has recently announced they were working on a new chip, whose name as yet to be decided, that will support both Wi-Fi and Bluetooth Low Energy. Details are sparse, but we do know the chip will come with 500KB RAM, support hardware SSL and possibly ECDH, deliver 500 DMIPS of performance, and consume 5 uA in deep sleep mode. The company asked for beta testers via their twitter account around 2 weeks ago, so I guess it’s a bit too late to apply. John Lee, working for Espressif, also said the new part should become available […]

Review of CX-S806 TV Box Powered by Amlogic S812 Processor

I’ve already reviewed one Android media player based on Amlogic S812 processor with MINIX NEO X8-H Plus. Today, I’m going to have a look at another S812 TV box, namely CX-S806, with lower specs, and less support, but that sells for half price compared to the MINIX device. I’ve already published pictures of CX-S806 media player and board, so today I’ll focus on testing the performance and features of the device. First Boot, Settings and First Impressions The package include a simple IR remote control, so I inserted two AAA batteries to give it a try, and it seemed to work OK, but as usual I switched to use Mele F10 Deluxe air mouse for the rest of the review. Since I’ve connected Ethernet and HDMI cables, a USB hard drive, a USB webcam, and a USB hub with two RF dongles for the air mouse and wireless gamepad, and […]
