Gadgeteer Pin Assignment confirmation


#1

@ GHI,

Can you please confirm the following assignments that I need to build a G120 base board :

ENC28
PIN GADGETEER / PIN G120 / FUNCTION ENC28
3V3 / 3V3 / -
5V / 5V / -
P3 / P0.5 / INT
P4 / P1.14 / RESET
P5 / P1.16 / WOL
P6 / P1.17 / CS
P7 / MOSI2 / SI
P8 / MISO2 / SO
P9 / SCK2 / SCK
GND / GND / -

µSDCARD
PIN GADGETEER / PIN G120 / FUNCTION MMC
3V3 / 3V3 / -
5V / 5V / -
P3 / P0.15 / PRESENCE
P4 / P1.6 / D0
P5 / P1.7 / D1
P6 / P1.3 / CMD
P7 / P1.11 / D2
P8 / P1.12 / D3
P9 / P1.2 / CLK
GND / GND / -

USB Client
PIN GADGETEER / PIN G120 / FUNCTION SD
3V3 / 3V3 / -
5V / 5V / -
P3 / * / STAT
P4 / USB D- / D-
P5 / USB D+ / D+
P6 / * / VBUS
P7 / * / JACKDET
P8 / - / -
P9 / - / -
GND / GND / -

In paticular :
Am I OK with the choice for Sdcard ‘PRESENCE’ ?
Do I really need the marked ‘*’ Pins to be plugged if I do not power the board via USB nor the JACK, also the ‘STAT’ that I can not see on the G120 documentation…
For RTC, do you confirm the need for a 32768KHZ Crystal, and do I need another external component to add with ?

Thanks for your feedback !

And a veery last but important question : Can I solder the G120 on the board by refusion ? I ask this almost for the BGA this is already soldered like this, and I hope will support the refusion on the base board…

Can someone Have a look please on this post…It will only take you few minutes :slight_smile:

Maybe He has an autorefresh request that alerts him when its shortname is used so…

GUS GUS GUS GUS GUS

:wink:

I assume refusion is Louis engrish for reflow :wink: (your english is 99x better than my french)
I have reflowed a G120 without killing it :slight_smile:


#8

Yes ! Refusion would be too much in temperature I guess ! :wink:


#9

@ Justin - In the meantime, any remark on my assignemt ?


#10

@ LouisCpro - Standby caller - looking now…


#11

Looks ok to me.
Only difference on my SD is i use P0.4 but that shouldn’t matter as long as it#s a P0 or P2


#12

Wonderful Justin ! Thanks for your feedback !

@ LouisCpro -

I grabbed a soldering iron and a breadboard and i can confirm the SD card is working with the suggested mapping, i did not used the P3 / P0.15 / PRESENCE
The CAN DW on CAN1 and CAN2 is also working with the mapping above.

and then i see that this was answered 5 day’s ago by Justin, i have to learn to put these things on my watch list…
