nova-hardware's Issues

Improper spelling

when a PPP session exists and the user executes the code sudo hologram modem disconnect the user is presented with the following:
Checking for existing PPP sessions Found existing PPP session on pid: [the pid that is found]
The error shows up on the next line:

R410 BOM doesn't match schematic and PCB

Hello,

Regarding the Hologram Nova Gerbers:

The following components are listed on the schematic and on the PCB, I don't see these components on the BOM.

L1, C1, C3, C4, C8, C7, C5, D6, D7, D8, D9.

Can someone help me understand why these are missing? Are these components no longer needed.

Several of these capacitors are used for decoupling and may be optional. But L1 is required as 0 ohm resistor to receive 5V from USB.

Additionally, there are components on the BOM (R11, R51, C43) that are DNI (not populated) on the schematic. Are these components required?

If anyone knows this would be very helpful! Thank you.

Altium is windows only please export in eagle\kicad compatible format.

Could you export the hardware files in eagle and kicad compatible formats? Altium is only available for Windows

R410 PWR_ON

UBlox documentation describes a sequence for activating R410 via PWR_ON signal low. Nova schematic shows PWR_ON linked to pin 2, an undocumented reserved pin. Does anybody know if this is an undocumented way to achieve PWR on automatically when power is applied to the R410 device? Or is there something amiss with the schematic?

Can't use UART without cutting traces

I'm very grateful for the fact that you provided pads to hook up to the UART of the Sara-R404 but unfortunately it can't be used without cutting traces. The Vusb has to be cut to the R404 else it doesn't even turn the UART on. This means one has to feed the 3.8V rail directly (which is OK per-se) but that means one has to cut the trace at the output of the regulator and also disconnect the "3.8V discharge" circuit. It would be nice if you could provide a solder jumper or two on a future rev so this type of surgery can be done reasonably easily, at least as easily as soldering stuff to the UART pads.
