nrf905 driver for OpenWRT

[Mustafa AYDIN]

Hi, How can I use nrf905 with an Openwrt based module? Are there any driver for operation systems? These modules have many gpios. Openwrt based modules are simply Wifi modules using openwrt distribution of Linux. I want to integrate them on a single pcb. I'm open to any idea or advice.

For prototyping you could connect the GPIOs on the module you have with the interface on the nRF905. It needs a few GPIOs, but it's basically SPI pluss a few additional to handle interrupts. www.nordicsemi.com/.../Product_Specification_nRF905_v1.5.pdf

Perhaps this guide will be of use. wiki.openwrt.org/.../port.gpio

It is also important to remember that the nRF905 can't handle input voltage higher than 3.6 V.
