Pitaya Go is an IoT development board with multi-protocol wireless connectivity

One of the challenges in starting a new IoT project is the question of what connectivity to use. Depending on the nature of a project, there are several wired and wireless connectivity options that can be used to power a project and ensure it’s a success. We have WiFi, Bluetooth, Zigbee, Zwave, LoRa, ZigFox, Thread, NB-IoT, 3G/4G, and others. You can use from anyone, but which one to use is another thing because most development board only support 1 or 2 of those. Well, with the introduction of the Pitaya Go, you don’t have to worry so much about that decision. The Pitaya Go is an IoT development platform with multiprotocol wireless connectivity built-in. The Pitaya Go is based on the Nordic’s high-end multiprotocol SoC nRF52840 and the Microchip’s extremely low power Wi-Fi network controller ATWINC1500B. The nRF52840 SoC is the most advanced member of the nRF52 Series SoC family, and it […]

Gateworks Ventana GW5910 SBC Targets WiFi, BLE & Sub-1GHz IoT Gateways

Freescale/NXP i.MX6 based Gateworks Ventana single board computers have been around at least since 2013 and were initially targeting networking processing applications for the industry. They could be used into all sort of gateways with cellular or WiFi connectivity for instance, thanks to the presence of mini PCIe sockets. But the latest Gateworks Ventana GW5910 SBC does not exclusively relies on mini PCIe cards for wireless connectivity, as it includes an onboard Laird Sterling 802.11b/g/n WiFi & Bluetooth module, as well as optional TI CC1352P dual-band Wireless MCU supporting Sub-1GHz and 2.4GHz RF, and an optional on-board u-blox GPS module, which should lower the total cost compared to solutions with mini PCIe cards. Ventana GW5910 specifications: SoC – NXP i.MX6 Dual Core Arm Cortex-A9 SoC Processor @ 800MHz System Memory – 512MB DDR3-800 SDRAM Storage – 256MB Flash System Memory, microSD card slot, mSATA socket Connectivity Gigabit Ethernet Port Onboard […]

$10 Nordic Semi nRF52840 USB Dongle Supports Bluetooth 5, Thread, ZigBee, 802.15.4, ANT and 2.4GHz Proprietary

Several weeks ago, as I noticed the lack of Bluetooth 5 USB dongles, I found MakerSpot CC2640 Bluetooth 5 USB stick based on Texas Instrument CC2640R2F Arm Cortex-M3 WiSoC. It’s not exactly a consumer products, and instead it’s more like a development kit, but it can still be inserted into the USB port of your computer or development board. Today, I found out Nordic Semi also made their own Bluetooth 5 – or is it Bluetooth 5.0 now, I’m really confused at this point – USB dongle for evaluation & development based on nRF52840 WiSoC. It’s not only for Bluetooth 5 though, as the multi-protocol SoC also supports Bluetooth Low Energy, Bluetooth Mesh, Thread, Zigbee, 802.15.4, ANT(+), and 2.4 GHz proprietary solutions. nRF52840 USB dongle (PCA10059) key features: Wireless Connectivity – Bluetooth 5, Bluetooth Low Energy, Thread, Zigbee, 802.15.4, ANT/ANT+, and 2.4GHz USB – USB 2.0 ports Expansion – 15x […]
