... the square pin is typically pin(1) so the alignment of the lower module would be with the module to the inside of the pine board... I can see the Rx and Tx pins labels on the end of the lower module; so its accessing uart2 ( ttyS2 ) on the PI bus... what are the other pin names on that board ? Also, clearly this board was not designed for use with any PI ( let alone the PI(1) ) and was designed for use on the Pine board. Supposedly they have been tested/ what is your question about this module ?
If you want to know can you plug it onto the PIb ( PI(1) ) by aligning pin(1), then yes. The module probably won't work, but it won't break anything on the PI. The PI's uart is on the same pins, but its called ttyS0, or serial0, ttyAMA0, ... as for the other pins ( depending on which ones are being used ) it may are may not work plugged into the PIb. You might want to take a meter (with continuity checker, and the lower module only) and trace where each of the upper module pins goes one-by-one.
Another way to say this is, if you trace the lower module to any of the pins higher than pin 26, the board is not going to be at all compatible with the PIb (twenty-six pin layout).
But, just because you trace all of the pins to the lower 26 pins (1 - 26) does not mean it will work !
Sure this is what i was going to do but if I had the schematic I can avoid the continuity task... But as there is no documentation on this module, I'm going to do the job.
Thx anyway for your time.
