Raspberry Pi 4, 3B+, 3 or 2 Model B only!
WTware for Raspberry Pi works only on Raspberry Pi 34/b], Raspberry Pi 3B+, Raspberry Pi 3 Model B and Raspberry Pi 2 Model B. Manufacturer: https://www.raspberrypi.org/products/ra ... 3-model-b/
Broadcom BCM2836 processor, 4 kernels ARM Cortex-A7, 1GB RAM, 4 USB ports, 100 Mbit ethernet.
Pay attention at the marked bold features when buying. Old Raspberry Pi versions were with another processor, 1 kernel and less than 1GB RAM. WTware won't work on old versions. Buy Raspberry Pi 2 Model B. Sometimes "Model B" is not specified, but number 3 or 2 must be. Raspberry Pi 1 Model B - another, old board, it won't work. Must be 3 or 2.
We bought our device on Aliexpress for $40 from this seller: http://www.aliexpress.com/item/2015-New ... 17842.html Delivery was less than month, board was ok.
My monitor USB hub power is enough for Raspberry Pi 2, no need in additional power supply.
You need microSD card. Even for network boot, microSD is still needed: there's no flash with BIOS on board, and code that will load boot images by network will be stored on microSD. My board detected old 64 MB microSD (MB, not GB), but failed to detect new 32 GB card.
Rate compared with other machines, wtware striped test, all measured were made for 1920х1080х16 bit:
RK3066 в CX-818 - 35.59 sec.
Raspberry Pi 2 - 29.8 sec.
RK3188 в K-R42 - 23.82 sec.
RK3288 в R89 - 12.72 sec.
Intel J1800 on D1800M, video=i915(f) - 9.0 sec.
Data volume is the same, fewer seconds mean faster drawing.
By default Raspberry Pi 2 sets 1920х1080 resolution.
Raspberry Pi 2 is tested by HDMI-DVI cable with old cheap 18.5" Philips 191V monitor and in it's standart resolution 1366х768. If Raspberry Pi 2 works with such device in such resolution, then it should work with most other digital (HDMI and DVI) monitors in other resolutions.
Monitor resolution for Pi is specified not in WTware configuration files, but in config.txt file on boot SD card. Detailed manual for this file is available on manufacturer site http://www.raspberrypi.org/documentatio ... fig-txt.md For 1366х768 resolution by HDMI-DVI cable I specified in this file two lines:
