Martin Schramm c8f621e3d2 ngff-cardem: prelim floppy power connector 
Generic RA 2,5mm 1x4 header w/ similar plastics
 2021-06-12 02:09:45 +02:00
Martin Schramm 03e99eefcf ngff-cardem: ERC+DRC done 
missing is a single ERC issue related to the floppy conn which
has to change its position and to a 90° type.

Martin Schramm a00ac53f69 ngff-cardem: length matching for USB3 2021-06-11 17:54:00 +02:00
Martin Schramm 92b29af7ee ngff-cardem: Simtrace LEDs' logic unified (solves #5472) 
SAM3 sinks LED current. SIMTRACE_LED_GREEN (PA18) is exposed to
front, and SIMTRACE_LED_RED (PA17) remains a chipLED on PCBA.
 2021-06-11 12:12:46 +02:00
Martin Schramm 27f711117d ngff-cardem: currebt state w/ zero airwires

... like in the QuadModem for the first slot, the secont one like
in the Simtrace

adresses: SYS#5472

Martin Schramm 4d4a4e69d8 ngff-cardem: bring /FLAG of IC1 to a GPIO (solves SYS#5477) 
GPIO is PA8 (former QMOD's 'SIMPRES2').

Note, that the OCP of the FPF2109 is 200mA; there is no 100mA version
in this series and w/ 1V8 lowest Vin.

PU and PD for default "modem gives SIM pwr".

PU to V_MODEM, and a TUN inverter to GPIO (PA26), so get "default on,
but with ability for software to override should it ever be needed".

Martin Schramm 485f8fad22 ngff-cardem: commiting current state 
* 100 x 90 mm area
* no SIM-Vcc switching yet
* 47/measures used for principal dimensions and some details
 2021-05-16 23:01:20 +02:00
Martin Schramm ed8d98e78d ngff-cardem: remove SIM switch trio and connect straight to pivot 
This way the close-pivot OE is the only which needs a pull-down.
Seven FET switches remain for other uses, four of them in a now
usused seperate OE group.
