May is the month of our System On Modules
Today our next SOM with RK3188 successfully was tested and OK.
This one is little beast comparing to A20 it have 4x Cortex-A9 vs 2x Cortex-A7 and runs on 1.6GHz vs. 1GHz so RK3188 makes total 16000 DMPIS vs. 3800 DMIPS for A20 (4.2 times faster) and vs. 965 DMIPS for RaspberryPi (16.6 times faster).
On the SOM there is:
RK3188 running at 1.6Ghz
1GB DDR3 memory
Power Managment Unit IC
optional 4GB NAND Flash
micro SD-card to boot Llinux or Android
two buttons
three status LEDs
debug UART console
5 GPIO connectors 2×20 pins 0.05″ step
RK3188-SOM and RK3188-SOM-4GB will be available for sale in June. The price of RK3188-SOM will be EUR 40 / 1000 pcs, the price of RK3188-SOM-4GB will be EUR 45 / 1000 pcs
RK3188-SOM-EVB is also available with Eagle CAD files, so any one can tailor board to his needs:
The RK3188-SOM-EVB reference design have:
RK3188-SOM-4GB module
4x USB Hosts
1x USB OTG
HDMI output
100MB Ethernet
RTC with backup battery
LCD connector compatible with A13-LCDxx A10-LCDxx, A20-LCDxx displays we have
2x UEXT connectors
2x 40 pin GPIO connectors
RK3188-SOM-EVB will be available for sale in June too and the price is EUR 85.00
Android and Debian Linux will be provided.
