Over at Itead they are selling an updated version of the Sonoff POW called the R2. This upgrade provides user-configurable overload protection, live current and voltage readings and 99% measurement accuracy.
And at Seeed Studio they have on pre-order the ReSpeaker Core v2.0. This upgrade looks more like an SBC as it now contains the RK3229 SoC with 1G RAM, 4G eMMC, SD slot, HDMI out, WiFi and 100MbE. Apart from that everything else is identical to it’s predecessor with 6 mic array, LEDs and Grove ports.
Way back in Weekly Roundup #38 we saw the Artik 530 starter kit. Well now Seeed Studio, in conjunction with Samsung, have available for pre-order the Eagleye 530. This is a Pi form factor SBC, what else, running the Artik 530 SoC with 1G RAM, 4G eMMC, WiFi, Bluetooth, GbE and ZigBee with everything else almost identical to the Pi. Except power is provided by DC jack, which is a good move. Or if you’re really desperate you can still use a micro USB port.
They also have their Cytron SmartDriveDuo, which is a DC motor driver that can handle up to 80A peak and 30A continuous on two channels. Has on-board MOSFETs that are switched at 18kHz to reduce noise and handles all the thermal and current overload protection for you. So all you have to do is control it via RC, PWM or UART.
Over at AdaFruit they have their AS7262 based 6 channel visible light sensor breakout which allows sensing red, orange, yellow, green, blue and violet colour intensities. Access is over UART using plain old AT commands.
SparkFun are also getting into Helium in a big way.
No, not that type of Helium but this type of Helium, which consists of a module called an Atom running a SAMR2 and SkyWorks FEM. It’s similar to LoRa in that it’s a long range, low power device.
