Rasberry Pi 4 Plates
As much as Pi 3 was an evolution step, the 4 brings a much larger jump forward. It further improved the processor performance with, by now, a standard upgrade to the newest Broadcom and a clock step-up from 1.4GHz up 1.5. The new process supports the new OS as the Raspbian got a new face of a Buster (name based on a Pixar dog from Toy Story). Unlike in the last OS update, there are slight incremental visual changes - so from the desktop view you might be able to see the update. Other than that the system got a security update, and it remains (as always with RPis) backward compatible as it stores the image of old systems. On top of that, we got a memory on board, which makes life once again easier. Check the detailed guide to the differences among the Raspberry boards on our blog and revise the glorious three - Raspberry in different memory variants (1GB, 2GB and 4GB).
€34.00 - €65.00
This little board is great for any type of prototyping - enables troubleshooting and debugging of any board with voltage from 0 to 5.5V. The board interprets the commands and sends them further via a proper protocol (ranging from UART through I2C up to HDD44780 LCD). The Pirate lets analyze as well the data sent back from the device to the computer terminal effectively allowing to decipher potential errors. The bootloader installed on the board enables the quick and easy update of firmware and changing the functionality of the board.
This board features PIC24FJ64 and FT232RL USB-to-serial chip enabling swift communication over the mini-B USB port. On the other end of the board 2x5 pin header is placed with detailed descriptions of each pin.
Connectivity of the new Raspberry Pi 4
Raspberry goes with spirit of the time and makes sure to be up to date with all the current trends and technology. Same goes for its connectivity solutions - on the new board we are getting in addition to old USB 2s a pair of new USB-3s, which are able to process data transfers up 10 times faster than the old standard. Seems a lot, doesn´t it?
Memory upgraded from microSD cards to onboard
While the old solution with an interchangeable memory cards was giving some flexibility, it was rather a strain and having the memory onboard definitely makes life easier. The new boards come equipped with the highest quality 1GB, 2GB or 4GB of RAM depending on which board version you choose giving already much more space than the old 1GB. But if you still need or want to further extend via SD, there still is a port so rest assured there will be no problems with that.
Fast wireless connectivity and other upgrades in Raspberry 4
On top of the above, the board got an upgrade to the new standard of Bluetooth (5.0) with low energy mode and maintained the WiFi dualband standard b-g-n-ac. Other changes include new HDMI (2 micro instead of a 1 standard in the old board) enabling connecting of two HD screens. On the power supply end, we get a switch from micro-USB to USB-C, so you will probably need a new power supply and potentially a new box.
