Microchip’s ENC28J60 is a 28-pin, 10BASE-T stand alone Ethernet Controller with on board MAC & PHY, 8 Kbytes of Buffer RAM and an SPI serial interface.
It takes just few components to get the ENC28J60 up and running and connected to a host microprocessor or microcontroller which support the standard SPI interface. Below I have designed a small ENC28J60 module. The ENC28J60 has a operating voltageof 3.3V, but the board is designed to run with 5V supply voltage, i.e. inculdes a 3.3 voltage regulator for the power supply and a 74ACT125 used as level shifter for the control lines. So it can be directly connected to any 5V microcontroller system. Optionally, an I2C EEPROM can be assembled on the board which can be used e.g. to store websites if the board is used in an embedded webserver environment.

The solution is an embedded module. Swedish company Embedded Artists will help you in tit by their top-class modules with NXP processors.
Embedded modules are still more used in many products, where so far a classic microcontroller was sufficient. As requirements for functionality of devices are increasing, including audio/video output, network- and USB connectivity, as well as a possibility to be programmed by a user, to change firmware, etc, the development is more and more demanding. For small and middle-sized companies it can easily happen, that in respect to a supposed sale, the expenses will never return. In the most cases, it´s better and at the end of the day even cheaper to rely on some of so called embedded modules. An embedded module (depending on a type) usually provides all necessary for controlling of our device and it is usually easily programmable thanks to a standard OS implemented (Linux, Android, Windows,…).
Embedded Artists products are based on top-class NXP processors LPC with Cortex M0, Cortex M3 and Cortex M4 cores, but also on older ARM7. As Embedded Artists have a closed cooperation with NXP (they are an NXP certified partner), they have an excellent knowledge of these perspective chips. Among
Embedded Artists can be found:
- development kits
- OEM boards suitable for direct usage in products
- “quick-start” boards
- education boards
- display boards
- various accessories for development support
From a final product and production point of view, the most interesting are the OEM modules. Embedded Artists provides a wide support to their products and for example notes for usage of OEM modules in praxis can be found in the OEM Integration guide. An example of a price calculation – decision “own development or an embedded module” is illustrated in the attached picture. Many Embedded Artists products are in our stock ready for immediate shipment. We´re able to deliver you any other Embedded Artists product with a short leadtime.

Embedded Lab’s new development board for PIC12F series microcontrollers:
The 12F series of PIC microcontrollers are handy little 8-pin devices designed for small embedded applications that do not require too many I/O resources, and where small size is advantageous. These applications include a wide range of everyday products such as hair dryers, electric toothbrushes, rice cookers, vacuum cleaners, coffee makers, and blenders. Despite their small size, the PIC12F series microcontrollers offer many advanced features including wide operating voltage, internal programmable oscillator, 4 channels of 10-bit ADC, on-board EEPROM memory, on-chip voltage reference, multiple communication peripherals (UART, SPI, and I2C), PWM, and more. Today we are introducing a new development board (rapidPIC-08 V1.0) for easy and rapid prototyping of standalone applications using PIC12F microcontrollers.

Cortado connects your physical things to the digital world. Itʼs an Arduino that youʼll never plug in, and it works on all your favorite platforms including mobile (Mac, Windows, iOS, Android). It connects via Bluetooth Low Energy, an efficient protocol meant for supporting low-power sensors. If there ever was a building block for the Internet of Things, this is it.
It’s so easy to interact with Cortado, we think it will inspire an entirely new interaction flow. To illustrate this, the pre-ordered units will be turned on before they ship. If you download our app, you will get a BLE notification on your iPhone when your Cortado is nearby. Youʼll even be able to program it while it’s still in the box!
For the next month we will be holding a pre-order campaign featuring our new product. This campaign includes a special pre-order discounted price for all backers. It will launch at $18 and will increase every day as the month goes on reaching a maximum of $24, which is discounted 20% from the retail price ($30).

Boosting a miniature size of 49 x 75 mm and a weight of 40 g, the board was aimed for simple implementations targeting the Cyclone IV up to 22,320 LEs. The device utilizes small spacers as legs and even an acrylic cover on top of the board to provide better protection making this Development kit (Devkit) the option to choose for robust applications while giving of a sleek feel to users as they get to look through the device’s glass-like cover. The DE0-Nano definitely is one device to consider in making portable design projects where portable power is essential.
Running at around $80, users already get to enjoy a lot of other on board features. The DE0-Nano is equipped with a 3-axis digital accelerometer designed for better sensing applications. Other on board features follow in the form of 2 separate extension headers plus a third header that supports an ADC converter with 8-channels and 16 I/O Pins, 8 user LEDs, Push buttons and DIP switches. DE0-Nano also provides a three-power scheme option for designers through a USB mini-AB port, 2-pin external power header and two DC 5V pins.
Upon connection to the host PC, the FPGA Devkit automatically powers up and the LEDs start fading in and out. Once host PC has loaded up the DE0-Nano Control Panel, the LEDs stop fading indicating a full user access of the device. The DE0-Nano Control Panel is a GUI that allows users to automatically verify hardware components of the board. Users get to play around the LEDs and a GUI representation is also provided for the Push buttons and DIP switches. The control panel also allows users to work around with the memory and verify accelerometer coordinates and even provides an ADC tab that allows users to monitor the voltage levels in the different channels. The DE0-Nano Control Panel has a user-friendly interface that provides a fast response GUI that readily illustrates all changes made in the actual board. In general, the device is a great development board. It already has everything on board without having to pay for a lot of extras. Despite the DE0-Nano being an entry-level device, the well thought out and compact design definitely makes it a very complete and functional development board.

Brian posted an article describing how he designed and built his business card:
A business card should represent a person’s expertise. My expertise is in creating unique circuit boards, so to celebrate this I wanted to create a USB thumb drive circuit that contains my resume and contact information. This was also a great way to experience coding for USB applications using the Cortex M series of microcontrollers. As a side note, I have done other projects with Cortex M including a simple serial relay and a USB keyboard emulator, but this is the first one that is exciting enough to write about.
