OKI 675001 Module Specification
Hardware Specification
The board is currently available in three standard configurations and fully custom platinum boards can be manufactured on request. There is no minimum quantity for a Platinum board but it is normally only cost effective for 25-50 units or more. For more information on a customised board, please contact sales.
The full feature list and the included items in the standard configurations are listed below:

Power Usage
The module may be powered either with a direct regulated 3.3V supply capable of provinding 0.5A or by a linearly regulated input with a range of 4.5V - 15V. Practical measurements taken from a gold specification module running uCLinux with active networking, serial and basic user CPLD code loaded gives a baseline current draw of 0.39A at 3.3V (1.29W).
Measurements using the linearly regulated input give the expected results of a 0.39A current usage at any point of the acceptable input voltage range, the excess power being dissipated as heat into the modules ground plane.
All figures are subject to a 1% measurement accuracy and are for guidance purposes only.
Software Specification
A comprehensive suite of software including uCLinux is provided along with our ABLE bootloader. These software offerings require SDRAM to run and hence are only available on configurations with SDRAM. The non SDRAM modules can still run user code as required from their SRAM. All specifications have NOR flash allowing programs and data to be stored in non volatile memory.
