TinySine Bluetooth, WiFi and USB Relays Come with an Optional Enclosure, Support Android and iOS Smartphones

It’s now fairly easy to find the hardware to create WiFi or Bluetooth controlled relays, but you usually have to design your own enclosure and Android app, and if you’d like something that’s ready to use out of the box TinySine wireless relays such as TSRB430 (Bluetooth) or TSRW430 (WiFi) might be an interesting option. There;s also a version with USB control. TSRB430 / TSRB430 / TSRU430 specifications: 4x Omron G8P 30A/250VAC | 20A/28VDC relay; SPST-NO (normally open) types. Connectivity – XBEE module either: Bluetooth Bee module based on CSR BC417143 Bluetooth 2.0 chipset Roving Networks WiFi Bee module with 802.11 b/g radio USB Bee module with a CP2102 USB to UART chip Power Supply – 12V/1A via 2.1mm jack with positive core polarity Dimensions – 122mm x 87mm x x 31mm (board) There are also versions with 2 and 8 relays. I kind of wish they had models taking 220V AC input instead […]

Raspberry Pi 3, ODROID-C2 and Pine A64+ Development Boards Comparison

Raspberry Pi 3 and hardkernel ODROID-C2 launched the same day, and together with Pine A64/A64+, are the only ultra low cost (<$40) 64-bit ARM development boards available or soon-to-be available, so I’ve decided to make a comparison of the three boards the same way I did with ~$10 boards with a Raspberry Pi Zero, C.H.I.P, and Orange Pi One comparison. I’ve used features of Pine A64+ instead of Pine A64 since features and price are closer to the other two boards. Text highlighted in green means a board is clearly better than the other two for a given features, while a red highlight means it’s the weakest of the three. Raspberry Pi 3 ODROID-C2 Pine A64 Plus Processor Broadcom BCM2837 quad core Cortex A53 processor @ 1.2 GHz(4x ~2760 DMIPS) Amlogic S905 quad core Cortex A53 processor @ 2.0 GHz(4x ~4600 DMIPS) Allwinner A64 quad core Cortex A53 processor @ […]

Review of K1 Plus Android TV Box with Combo DVB-S2/DVB-T2 Tuner

VideoStrong has launched K1 Plus TV box powered by Amlogic S905 processor last year, and I had the chance to review their model last November. But here I am reviewing K1 Plus again. Why? That’s because the company’s has several K1 Plus models: the “standard” version that’s just like any Android TV boxes, and the DVB version with DVB-S2, DVB-T2/C, or DVB-T2/C + DVB-S2 combo, and the latter is the one I’m reviewing today. K1 Plus DVB combo teardown revealed that the main board was exactly the same as K1 Plus “standard”, and that only a tuner card was added. So I’ll have a two part review with the first part checking if they fixed any of the bugs found on K1 Plus “Standard” with “November 2015” firmware in the new “January 27, 2016 DVB” firmware, and the second part will focus on testing DTV app with DVB-S2 and DVB-T2, […]

Raspberry Pi 3 Model B Board Features a 64-Bit ARM Processor, Adds WiFi and Bluetooth Connectivity

The Raspberry Pi foundation is working on yet another model of the popular Raspberry Pi boards, as the Raspberry Pi 3 model B board has showed up on the FCC website. The new board looks very similar to Raspberry Pi 2 model B, but adds on-board WiFi 802.11 b/g/n (2.4GHz only) and Bluetooth 4.0. Let’s play “spot the difference” with Raspberry Pi 2 at the top and Raspberry Pi 3 under. The processor looks the same as the BCM2836 quad core Cortex A7 SoC found on model 2 B, but one redditer claims it could be a 64-bit processor due to some MagPi ad. [Update: that’s the MagPi ad which confirms Raspberry Pi 3 will feature a 64-bit ARM processor @ 1.2 GHz. Thanks Gabe! ] We’ll find the WiFi/BT chip antenna on the top left corner, and two through holes on the right of the 40-pin connectors, likely the […]

Rockchip RKi6000 Low Power WiFi SoC Showcased with IoT Demo Board

Announced last year, Rockchip RKi6000 SoC promised WiFi connectivity at Bluetooth 4.0 LE power consumption levels, and the company has recently showcased the technology with a demo board controlling four lightbulbs. The chart above shows Rorkchip solution can transmit data at 802.11b speeds (11 Mbps) while still keeping power consumption low at around 10mW, similar to BT LE, and good enough to run on batteries. Peak Tx and Rx power has gone up a little since the first announcement, as the company now claims 66mW @ 11 Mbps instead of just 60mW. While there’s basically zero information about the chip on Rockchip website, you may have noticed a QR code on the product brochure in Charbax video linking to Rockchip IoT Club, which you can join as long as you work for a company with a specific project in mind.
