Raspberry Pi version A+
New version of the popular Raspberry Pi mini-computer model A+. The device can successfully be an alternative to desktop computers. Its main advantages are: easy to use operating system, low power consumption, small size, performance at Pentium II level and mounted sockets: 1 x USB, HDMI, audio/video jack, 40 pins GPIO and microSD slot for memory card andmicroUSB topower the chip.
What's new in A+?
- 40 GPIO pins instead of 26.
- The tile size has been reduced.
- The SD card slot has been replaced by a micro SD slot.
- There is a new step-down regulator for 3.3V and 1.8V.
- Sound quality has been improved.
- Composite socket (NTSC/PAL) has been integrated with a 4-field 3.5 mm jack.
- Four mounting holes have been added.
- The spacing of connectors has been changed, the existing enclosures will not fit.
- Protection against reverse polarity of supply voltage has been added.
What hasn't changed?
- Broadcom CoS BCM2835 700 MHz processor, graphics and RAM - 256 MB.
- HDMI 1.4 socket compliant with 1.3.
- MicroUSB power connector.
- Software - existing operating systems will be compatible.
- The first 26 GPIO pins are the same.
- Connector for dedicated camera.

Differences from the B+ version
- A+ has 1 USB port, while B+ has 4.
- A+ has no RJ5 Ethernet socket.
- The A+ board is smaller, its dimensions are 65 x 56 mm
- A+ draws less current: approx. 500 mA (up to 1.5 A at peak).
Image and sound
The Raspberry Pi hasa HDMI version 1.4 connector, through which both video and audio can be transmitted. In addition, the board is equipped with a 4-field 3.5 mm jack socket, to which you can connect headphones, speakers or output video via RCA Composite standard. In our offer you will find a suitableJack - RCA cable.
Operating system
The raspberry drive isa microSD memory card. The operating system can be uploaded using a computer with a reader. In our shop there arecards with NOOBs program installed, which at the first start allows you to choose from the systems: Raspbian, Pidora Openelec, RaspBMC, RISC OS, Aarch Linux.
Communication
Malina has basic communication interfaces that can be found in PC-class office computers. In addition to the previously mentioned audio and video interfaces, the user has at his disposal:
- USB connectors,under which you can connect e.g. a mouse, a keyboard, a WiFi card or a flash drive. If it turns out that there are too few sockets, you can increase their number usingan external USB HUB.
- GPIO- general purpose outputs/inputs that can be used to operate LEDs, buttons, motor controllers. Among them there are pins supporting I2C, SPI and UART interfaces. In the B+ version the number of GPIOs has been increased from 26 to 40.
Power supply
The system uses the microUSB connector as its power source. In practice, this means thata mobile phone charger witha minimum capacity of 1 A can be used to run Rasbperry Pi.
Accessories compatible with version A+
Most of the modules using GPIO connectors (with the exception of Audio circuits such as Wolfson) will continue to work properly with the new version of raspberry. Devices using USB (e.g. WIFi) and HDMI ports will be compatible. You can also successfully connect a dedicated camera to A+ version:standard, daytimeorNoir versionwithout UV filter.
Accessories that will not work with A+ version
Audio overlays that use additional connectors (derived as soldering pads) will not work with the new version. Attempting to connect the GPIO 26-pin cable will result in bending the Raspberry A+ connectors. The spacing of the sockets has also changed, so the existing housings are not compatible with the A+ model.
