Adapter Enables Offline Speech Board to Work with Raspberry Pi
Audeme has released a $6.50 "Raspberry Pi MOVI Adapter" board and API to enable a Raspberry Pi pairing with its MOVI Arduino Shield for offline speech recognition and synthesis. We're used to seeing Arduino compatible, MCU-driven HATs and other add-ons for the Raspberry Pi, but in 2015 Audeme flipped that combo on its head with a Linux-driven voice shield for the Arduino called the MOVI Arduino Shield Speech Recognizer and Speech Synthesizer. At the recent Maker Faire Bay Area 2019, the company released a $6.50 adapter board that lets the MOVI Arduino Shield work with a Raspberry Pi.
The $75 MOVI (My Own Voice Interface) Arduino Shield offers "Internet-free" speech recognition and synthesis for up to 150 customizable English sentences. MOVI offers voice control for applications like turning devices on and off, entering alarm codes, and carrying on programmed conversations. The device is speaker independent, so there's no voice training involved, and it uses no cloud services, thereby enabling offline applications free from privacy or reliability concerns.

Small Form Factor SBC Serves UpKaby Lake Processors
American Portwell Technology has launched the WUX-7x00U, a small form factor (SFF) embedded board featuringIntel Core i5 7300U and i3 7100U processors, formerly codenamed Kaby Lake. The Intel processors integrate the Intel HD 620 graphics engine with 24 execution units, enabling enhanced 3D graphics performance and higher speed for 4K encode and decode operations. Portwell says the embedded board is well suited for applications such as medical equipment, IoT gateway, industrial automation, warehouse automation, digital signage and more.
Portwell's WUX-7x00U embedded board, designed with a compact footprint (101.6 mm x 101.6 mm; 4˝x 4˝), features up to 32 GB DDR4 SDRAM and multiple storage interfaces like 1x SATA III port and 1x M.2 Key M for SSD. For functionality extension, it provides 3x USB 3.0 ports and 1x USB 3.0 Type-C port.

Enclustra FPGA Modules Power Electric Racing Car
Formula Student is the largest engineering competition in the world. The Zurich/Switzerland based AMZ student team managed to put itself top of the world rankings, also thanks to the innovative, FPGA module-based approach for the electric drivetrain. Four self-developed inverters control one motor each. A self-developed direct torque control (DTC) modulator is running on a Xilinx Zynq 7015 FPGA-System-on-Chip based Mercury ZX5 SoC module from FPGA expert Enclustra.
VHDL implementation makes it possible to estimate the current state of the motor and calculate the new switching positions every 10 ns---capabilities not possible with a microcontroller- or DSP based system. The module-based approach reduced development time and risk significantly. The Mercury ZX5 SoC module provided exactly all needed functionality on one single small PCB. The module even can power circuits on the base board, minimizing the need for power converters.

Open-Spec Omega2 LTE SBC Features Cat 4 and GNSS
Last December, Onion updated its MIPS-based, WiFi-enabled Omega2 board with a similarly OpenWrt-driven Omega2 Pro SBC that increased RAM to 512 MB and flash to 8 GB and added real-world USB host and micro-USB ports. Now, the company has returned to Crowd Supply with a similarly open source, OpenWrt Linux driven Omega2 LTE model with 4G LTE and GNSS location connectivity. Pricing ranges from $99 for the board alone to $199 for a fully loaded "Ultimate Collection" kit, all with early August shipments.
The Omega2 LTE is not based on the Omega2 Pro, but rather the earlier, surface-mount Omega2S+ compute module version of the Omega2 announced back in 2017. Designed for the OEM market, the 42.9 mm x 26.4 mm x 9.9 mm Omega2S+ module is equipped with the same MIPS-based, 580 MHz MediaTek MT7688 SoC with 2.4 GHz 802.11b/g/n radio found on the Omega2 and Omega2 Pro. However, it has a smaller allotment of 128 MB RAM and 32 MB flash.

Mini-PCIe Modules Offer Cat-M1 and Iridium Modems for IoT
Gateworks announced a pair of mini-PCIe modems that have been tested---and offer tech support---only on the company's Linux-based SBCs. Most recently, these include the Cavium Octeon-based Newport GW6100 and GW6200. The GW16126 with Cat-M1 and BLE 5.0 and the GW16130 satellite modem will likely work with other mini-PCIe equipped computers. The GW16126 requires a Linux host computer, while it appears the GW16130 may also work with other operating systems.
The GW16126 (shown) supports Bluetooth 5.0 LE (BLE), as well as Verizon's new low-power wide-area (LPWA) Cat-M1 service, which we saw recently on Advantech's ICR-3211Brouter. Cat-M1 offers 375 Kbps, half duplex up/down speeds for IoT or machine-to-machine (M2M) communications. It's touted for its low power consumption and exceptional in-building range.
