Hackaday Prize Entry: Smart USB Hub And IoT Power Meter

by Moritz Walter August 02, 2016

[Aleksejs Mirnijs] needed a tool to accurately measure the power consumption of his Raspberry Pi and Arduino projects, which is an important parameter for dimensioning adequate power supplies and battery packs. Since most SBC projects require a USB hub anyway, he designed a smart, WiFi-enabled 4-port USB hub that is also a power meter – his entry for this year’s Hackaday Prize.

[Aleksejs’s] design is based on the FE1.1s 4-port USB 2.0 hub controller, with two additional ports for charging. Each port features an LT6106 current sensor and a power MOSFET to individually switch devices on and off as required. …read more

New Chip Alert: RTL8710, A Cheaper ESP8266 Competitor

by Brian Benchoff July 28, 2016

Almost exactly two years ago, shocking news thundered across the electronics blogosphere. There was a new WiFi module on the block. It was called the ESP8266, a simple serial device capable of taking care of an 802.11 network and a WiFi stack, giving any project with a microcontroller access to the Internet. Earlier modules to connect microcontrollers were sufficient for the task, but nothing could beat the ESP8266 on price.

Now, there’s a new module that’s even cheaper and more powerful than the ESP8266, and just like all of our favorite parts from China, it inexplicably shows up on eBay …read more
