BML project for using a $2 FTDI FT260Q for adding 14 bits of GPIO to any PC via USB with no device drivers required.
Ever miss the simple days of using a PC’s LPT1 parallel port to bit-bang GPIO over 8 output pins and 4 input pins of the DB-25 connector? I sure do. My first design project as a BSEE graduate in 1993 was to design a LPT1 controlled test fixture for the Motorola MDT-9100-T data terminal (shown below). Those were the days. By multiplexing 12 parallel port pins into 74HC dip CMOS latches and transceivers my test jig tested all the IO signals of the MDT-9100s 386sx motherboard. All of the diagnostic software could be written in C on my Windows 3.1 desktop thanx to this versatile interface. Those were the glorious simple days of computing. Sigh…. Then USB came along and killed the wonderfully easy parallel port interface.
Renesas Electronics Corporation, a significant supplier of advanced semiconductor solutions, announced its latest industrial Ethernet module solution, the I-RJ45. It combines a single- or dual-port RJ45 connector and simplifies integration for industrial Ethernet by supporting various industrial network applications including sensors and transmitters, gateways, operator terminals and remote I/O.
This new device is an intelligent RJ45 module that comes with specialized embedded software that supports multiple industrial Ethernet protocol stacks. The software package and sample codes provide system manufacturers with a complete set of tools and frameworks to build their application. This helps to prototype systems, reducing the time needed for industrial network protocol integration. The modules are 50 x 17.5 x 12mm (single) and 50 x 35 x 12mm (dual).
With a general Application Programmable Interface (API), the application can easily be connected to the protocol software. It offers a seamless integration path to other Renesas ASSP solutions. The single-port version of the RJ45 module is based on the RX64M microcontroller (MCU) Group and the dual-port module solution includes the R-IN32M3 industrial Ethernet communication chip.
Renesas also offers a solution kit version of the module that consists of a single or dual-port industrial Ethernet module attached to an adapter board for development. This adapter board enhances the module to connect with Arduino and Pmod interfaces, which enables it to connect to other Renesas MCU development boards including Renesas Synergy™ and RX. The Ethernet module solution kit also includes a quick start-up guide, a USB cable and a CD with software and documentation.
Samples of the I-RJ45 industrial Ethernet module solution are now available worldwide. The mass production is scheduled to begin in Q3, 2018. The industrial Ethernet module solution kit may be available in April 2018 and projected price of €299.00 per kit.

The OSD3358-SM-RED from Octavo Systems is a reference, evaluation, and development board for the OSD335x-SM series of System-in-Package (SiP) devices. It is powered by a 1 GHz processor, ADC, and 1 GB of DDR2 RAM into an enclosure of the size of a coin.
The SiP needs a PCB, along with components like an Ethernet jack, power supply, IO pins, and USB sockets to communicate with the other complimentary electronic parts. These boards include several power options, including a micro-USB connector, barrel jack, and solder points for battery usage. Ethernet and USB connectors are included, along with expansion connectors setup so that BeagleBone Black Capes can be connected directly. Finally, a 9-axis IMU, barometer, and temperature sensor are included. Data from sensors can be collected directly without the help of extra hardware or software.
This board is longer and slightly wider than a Raspberry Pi, at an exact dimension of 108 x 54 mm. It’s also thicker at 32 mm due to the decision to mount the Ethernet jack on top of the two USB ports. A micro-SD card slot is included, though WiFi capability is not provided. For internet connectivity, the user needs to rely on wired or dongle connection.
It comes pre-loaded with a Debian Linux distribution, complete with drivers for the onboard sensors already available. It can also boot off of the SD card to load other Operating Systems. This board can be used in one of three ways: as a standalone device, a USB client, or using a UART port as a Linux terminal. In the standalone case, the user simply connects the micro-USB connector to an appropriate power source, then to a monitor via a micro-HDMI to HDMI adapter. Once booted up, the screen goes to a minimal Linux install, allowing the user to access a web browser, terminal, and other necessary tools that a developer can build upon.
At a cost of $199, this board wouldn’t be an appropriate substitute for a Raspberry Pi or BeagleBone in standalone situations, but it will certainly be useful for a professional upgrade to OSD335x-SM SiPs.
MYIR Tech has launched an $85 module, Xilinx Zynq-7010 or -7007S that runs on MYC-C7Z010/007S CPU Module. MYC-C7Z010/007S CPU Module is a part of their newly launched sandwich-style, $209 MYD-Y7Z010/007S Development Board. There’s an open source Linux 3.15.0 based BSP for the module, and the MYD-Y7Z010/007S carrier board ships with schematics. Both the module and development board can withstand -40 to 85°C temperature range.
MYC-C7Z010/007S CPU Module
Xilinx’s Zynq-7010 has dual-coreArm Cortex-A9 block as the Zynq-7015 or Zynq-7020, which is available along with the Z010 on the earlier MYC-C7Z010/20 module. However, the Zynq-7010 SoC has more FPGA logic cells (28K). On the other hand, the Zynq-7007S is limited to a single Cortex-A9 core and a 23K logic cell FPGA. The Zynq-7010 ranges from 667MHz to 866MHz while the 7007S can operate from 667MHz to 766MHz.
The MYC-C7Z010/007S has 75 x 50mm dimension. It ships with 512MB DDR3 SDRAM, 4GB eMMC, and 16MB quad SPI flash. There’s a Gigabit Ethernet PHY and external watchdog. A 1.27mm 180-pin stamp-hole (Castellated-Hole) expansion interface is also there for ARM and FPGA interfaces that are useful to improve shock resistance. Supported I/O incorporates single USB and SDIO interfaces plus a pair of serial, I2C, CAN, SPI, and 16-channel ADC.
MYD-Y7Z010/007S dev board
The 153 x 80mm MYD-Y7Z010/007S Development Board expands the MYC-C7Z010/007S CPU module with 3x GbE ports, a USB 2.0 OTG port and a DB9 combo port with isolated RS232, RS485, and CAN signals. There’s also a microSD slot for memory expansion and a debug serial port.
An optional, $29 MYD-Y7Z010/007S I/O Cape plugs into the GPIO interface offering an HDMI port, a user button, and LCD, camera, and dual Pmod connectors. The LCD interface supports optional MYIR 7- or 4-inch capacitive and resistive LCD modules. The HDMI port only supports 720p resolution for now. The MYD-Y7Z010/007S board is further equipped with a reset key and boot switch. There’s also a 12V/2A DC input.
The MYC-C7Z010/007S module with the Zynq-7010 is available now for $85. The MYD-Y7Z010/007S Development Board is available with the Zynq-7010 based module for $209. More information is available at MYIR’s MYC-C7Z010/007S and MYD-Y7Z010/007S product pages.
A 10.8A, 4 port USB charger with a wattmeter and adaptive intelligent charging.
It works by taking any DC input between 7V to 17V, from an AC/DC adapter or car adapter. It can be used anywhere with wall outlets, car power ports, lead-acid batteries, DC-output solar panels, and lithium-ion battery packs (2S, 3S, and 4S).
It then drops the voltage down to 5V and intelligently adapts to match the maximum current the device being charged would accept. We believe it is the most powerful 4-port USB charger at 10.8A. No device is throttled when every port is in use.

Comma.ai is a self-driving car startup founded by George Hotz, the American hacker known for unlocking the iPhone and the PlayStation 3. Comma AI who originally wanted to build self-driving car kit, canceled their initial project due to safety concerns from NHTSA but later open-source their project and has now launched a Panda, an On-Board Diagnostics (OBD) II adapter that is expected to expose a car sensor data with the hopes of turning that information for self or assisted driving application.
Panda is a small size OBD II dongle and will plug into the port of most new cars made since 1996 with preference giving to vehicles of 2010 and above. Panda supports 3 CAN (Controller Area Network), 2 LIN (Local Interconnect Network) and 1 GMLAN (General Motor Local Area Network) for access to almost all of the sensors in most of the cars on the road. It also includes WiFi and USB port to help interface with a computer and smartphone.
With a dimension of 34 mm x 50 mm x 27 mm, Panda can read a host of data. Panda will be able to measure the car speed, location (if available), fault codes, braking force, engine speed, gas level, and many more. To help parse all that information Comma AI also launched Cabana a CAN analysis tool.
Panda can be paired with Openpilot, the company’s open-source autonomous driving software and this pairing could be used to take control of a compatible vehicle’s gas, brakes, lights, and steering.
