The Raspberry PI 2 B is now available — it has a quad core ARM Cortex-A7 CPU and 1GB of RAM. The price is still the same as the Raspberry PI B+ and it is compatible with the Raspberry PI B+.
For more information, see the post on the Raspberry PI website.
The new Raspberry PI Model A+ board has been launched this month. It is a smaller version of the Model A and shares some of the features of the model B+. The board size is 56mm wide by 66mm long and 14mm high.
This video from RasPi.TV has more details on the new board:
The RasPi.TV blog has more details and photos of the new Raspberry PI board.
The Raspberry PI laptop computer reported in Elektor News was created using a 3D printer for the case, model B+ Raspberry PI, laptop keyboard, track-pad, WiFi, battery and 13.3″ HD screen. The battery lasts 6 to 8 hours.
The name for this laptop is “PI-TOP”, you can read more about it on the Pi-Top website and also follow the project on Facebook for updates.
The Atmel SAM4N Xplained Pro evaluation board contains a ATSAM4N16C microcontroller. The board itself is rather basic with only one user programmable LED and one user programmable push-button switch (the second switch is a reset switch). Pins of the microcontroller are available on headers on the board.
An on-board Embedded Debugger is included on the board, so that no external tools are required to program or debug the ATSAM4N16C.
The video below shows the evaluation board being unpacked.
Some features of the ATSAM4N16C microcontroller are:
- ARM Cortex-M4 that can run up to 100MHz
- 3 USARTs and 4 UARTS
- Real Time Clock (RTC) with calendar and alarm features
- 10 bit ADC and DAC
- 1Mb Flash memory
- 80kb SRAM
- The usual SPI, TWI, timers, PWM, etc.
The ATSAM4N16C does not contain any USB ports, Ethernet or external bus.

The Raspberry PI Model B Plus is now available. The first thing to note about the B+ model is that you will need to load your operating system of choice to a micro SD card, so don’t forget to order one if you don’t already have one.
Raspberry PI B Plus
Some of the other major changes are:
- There are now 4 USB host ports on the board
- The I/O pin header now has 40 pins instead of 26 pins
- The new micro SD card socket now latches the card: push the card in to lock it in the socket, push the card again to unlock it
- The composite RCA socket has been removed
