Ivy5661 Bluetooth 5 + 802.11ac WiFi IoT Board Up for Pre-order for $35

There are many WiFi and/or Bluetooth board designed for the Internet of Things thanks to ESP8266 / ESP32, and other solutions, but usually they all work in the 2.4 GHz frequency band which can be an issue in crowded environments. Last October, we covered ucRobotics Ivy5661 96Boards compliant IoT board that offers a dual core Arm Cortex-M4F MCU with 802.11ac WiFi 5 and Bluetooth 5 connectivity. It was still under development at the time, but today, I’ve noticed it was listed on Seeed Studio for $35 with shipping scheduled for the end of February. ucRobotics Ivy5661 board specifications: SoC – UniSoC UWP5661 dual core Arm Cortex-M4 microcontroller @ 416 MHz manufactured with 28nm process Storage – 32Mbit NOR flash Connectivity (built in SoC) Dual band 802.11ac 2×2 MIMO WiFi 5 up to 866MHz; supports repeater mode, RTT indoor positioning Bluetooth 5 with support for high power mode, BT mesh, and […]

OpenISA VEGAboard Combines RISC-V and ARM Cortex-M Cores

OpenISA has launched an Arduino compatible RISC-V development called VEGAboard that features RV32M1 wireless microcontroller with a RISC-V RI5CY core, a RISC-V ZERO-RISCY core as well as Arm Cortex-M4F and Cortex-M0 cores, and a radio operating in the 2.36 GHz to 2.48 GHz range. An external NXP Kinetis K26 Arm Cortex-M4 MCU is added to the board for OpenSDA (Open-Standard Serial and Debug Adapter) debugging over a single USB cable. The board was offered for free, I’m just not sure when, but they are already out of stock. Hopefully, they’ll start selling the board soon enough. VEGAboard (RM32M1-VEGA) board key features and specifications: Ultra-low-power RV32M1 Wireless MCU supporting BLE, Generic FSK, and IEEE Std 802.15.4 (Thread) platforms IEEE Std. 802.15.4-2006 compliant transceiver supporting 250 kbps O-QPSK data in 5.0 MHz channels, and full spread-spectrum encoding and decoding Fully compliant Bluetooth v4.2 Low Energy (BLE) Reference design area with small-footprint, low-cost […]

Raspberry Pi Compute Module 3+ Launched with Broadcom BCM2837B0 Processor, Up to 32GB Flash

Raspberry Pi 3 Compute Modules CM3 and CM3L launched about two years ago based on Broadcom BCM2837 quad core processor found in Raspberry Pi 3 board. Last year, the Raspberry Pi Foundation introduced Raspberry Pi 3B+ board with a slightly faster Broadcom BCM2837B0 processor, Gigabit Ethernet, and WiFi 802.11ac. So it would have made sense for the foundation to provide an upgrade to their CM3 compute modules with Broadcom BCM2837B0 processor, and that’s exactly what they’ve done with the launch of Raspberry Pi Compute Module 3+ for $25 and up. There are four variants of Raspberry Pi Compute Module 3+ with different storage options and sharing the following specifications: SoC – Broadcom BCM2837B0 quad core Cortex A53 processor @ 1.2 GHz with Videocore IV GPU System Memory – 1GB LPDDR2 SDRAM Storage CM3+/Lite – SD card signals through SO-DIMM connector CM3+/8GB – 8GB eMMC flash CM3+/16 GB – 16GB eMMC […]

Toybrick RK3399Pro Board is equipped with Rockchip RK3399Pro AI processor

We’ve heard about Rockchip RK3399Pro processor that adds an NPU (Neural-network Processing Unit) to Rockchip RK3399 hexa-core processor for about a year now. We’ve seen the official Rockchip RK3399Pro EVB in action last November, but this type of board is not usually for sale to the general public. The first RK3399Pro board that you could technically spend money on was Khadas Edge-1S via a crowdfunding campaign, but it’s still unclear when it will ship. Another option that I just discover is Toybrick RK3399Pro (TB-RK3399Pro) single board computer by VAMRS. Toybrick RK3399Pro board preliminary specifications: SoC – Rochchip RK3399Pro hexa-core big.LITTLE processor with 2x Cortex A72 cores up to 1.8/2.0 GHz, 4x Cortex A53 cores @ 1.4 GHz, and an Arm Mali-T860 MP4 GPU with OpenGL ES 1.1 to 3.2, OpenVG1.1, OpenCL 1.2 and DX 11 support, and NPU delivering up to 3 TOPS System Memory – 3 or 6 GB […]

Cost-Optimized Rock960 Model C Board Sells for $69 and Up

96Boards compliant Rock960 board launched last year for $99 with Rockchip RK3399 processor, 2 to 4GB RAM, 16 to 32GB eMMC flash for $99 and up. However, now you can buy a Rockchip RK3399 SBC for as low as $45 plus shipping thanks to FriendlyElec NanoPi NEO4 board that comes with 1GB RAM and no built-in storage, relying instead on a micro SD card slot or eMMC socket. So VAMRS decided to design a cheaper version of their board with Rock960 model C that still benefits from being part of the 96boards ecosystem, is equipped with 1, 2 or 4GB LPDDR4 RAM, and the OS can boot from a micro SD card or an optional eMMC flash module. The 1GB version of the board is now sold for $69 on Seeed Studio with shipping scheduled for the 1st of February 2019. Rock960 model C preliminary specifications: SoC – Rochchip RK3399 […]

Orange Pi 3 Allwinner H6 SBC Comes with GbE, USB 3.0, mPCIe

When Shenzhen Xunlong Software launched their first Allwinner H6 development board, Orange Pi One Plus, many were disappointed as the board did not make use of some of the key features of H6 processor like USB 3.0 or PCIe, and RAM was limited to 1GB. A couple of weeks later, the company introduced Orange Pi Lite2 board with 802.11ac WiFi, a USB 3.0 port, HDMI 2.0a output, but no Gigabit Ethernet, nor PCIe interface, and again only 1 GB LPDDR3 memory. The good news is we now get a full-featured Allwinner H6 SBC thanks to Orange Pi 3 equipped with up to 2GB RAM, an optional 8GB eMMC flash, Gigabit Ethernet, 802.11ac WiFi 5, four USB 3.0 ports, HDMI 2.0a, a mPCIe slot, and more. There are four variants of the Orange Pi 3 board with either 1 or 2 GB RAM, with or without eMMC flash that share the […]

Orange Pi RK3399 Board Gets 4GB RAM for $100

Orange Pi RK3399 development board launched last year, further crowding the RK3399 space. The board did not target the lower end of the market with a $109 price tag, but still came with only 2GB of RAM. Shenzhen Xunlong has now introduced a 4GB RAM version of the board for $99.96, with the 2GB version now selling for $89.38. Both boards can be purchased on Aliexpress. Apart from the RAM capacity, Orange Pi RK3399 “4G” specifications have not changed: SoC – Rockchip K3399 hexa-core big.LITTLE processor with two ARM Cortex A72 cores up to 2.0 GHz, four Cortex A53 cores, and an ARM Mali-T860 MP4 GPU with support for OpenGL 1.1 to 3.1 support, OpenVG1.1, OpenCL, and DX 11 System Memory – 4 GB DDR3 Storage – 16 GB eMMC flash, micro SD card, mPCIe (for mSATA/LTE), and SATA interface Video Output/Input & Display Interfaces 1x HDMI 2.0 up to […]
